DogDoctorOfficial Hello GrowDiaries family! 👋🌱
Welcome to another new journey, and this time we're following Blueberry Muffin by Zamnesia – Pheno B.
Before we begin, I'd like to mention a small change in the way I'll be documenting this run. Due to the current photo limitations on GrowDiaries, I've decided to separate each phenotype into its own dedicated diary. Instead of documenting multiple plants within a single journal, each phenotype will now have its own space from seed to harvest.
This approach allows me to continue documenting every stage as thoroughly as possible while selecting the best photos from each week. The goal remains exactly the same as always: to create a complete educational record of the grow, sharing not only the successes, but also the challenges, observations, and lessons learned along the way.
For those following my previous diaries, you'll already know that this cultivation style is a little different from what many growers choose. Over the years it has become part of my own growing philosophy, and throughout this journey I'll do my best to explain not only what I'm doing, but also why I'm doing it.
So let's begin at the very beginning: germination.
For this run, all genetics are provided by Zamnesia Seeds, while the substrate and nutrient line come from Plagron. Blueberry Muffin has built quite a reputation among growers for its beautiful structure, vibrant colors, and unmistakable aroma profile, making it a cultivar I've been looking forward to documenting from seed to harvest.
To start the seeds, I used the Cannakan germination system. For those unfamiliar with it, it is a simple but practical germination container that allows multiple seeds or cultivars to be organized separately while maintaining a stable environment. Each compartment can be individually labeled, making it easy to keep track of genetics throughout the germination process.
The seeds were placed in plain water inside the Cannakan and left to hydrate. Within roughly 24 hours, healthy taproots had already emerged and the seeds were ready for the next stage.
This run also marks my first experience using coco starter plugs. The plugs were thoroughly hydrated, lightly squeezed to remove excess water, and the germinated seeds were carefully placed inside. They then spent approximately 24 hours inside a propagation dome where humidity remained high enough to support early development.
The response was immediate. Before the first full day had passed, the seedlings were already emerging, opening, and searching for light. At that point I decided to transplant them directly into small containers filled with Plagron Lightmix.
At this stage, the only thing they receive is water.
Seeds already contain everything required to support their initial development, so I prefer not to introduce nutrients during germination. The objective is simply to provide moisture, oxygen, warmth, and a stable environment while allowing the seedling to establish itself naturally.
Environmental conditions were kept intentionally simple. Temperatures remained around 26–27°C, while humidity stayed between 65–70% thanks to the Spider Farmer humidifier. While many growers prefer keeping seedlings inside a dome for extended periods, I personally like introducing them to the ambient environment early. A method that may differ from more traditional approaches, but one that has become part of my own cultivation style over time.
Airflow was kept extremely gentle during these first days. Seedlings need fresh air, but excessive airflow can quickly become counterproductive. At this stage, less is often more.
For bottom heat, a propagation mat was used and maintained around 40°C. The reason for this is simple: heat sources generally need to operate slightly above the target root-zone temperature in order to compensate for environmental losses and maintain consistent warmth where it's actually needed.
Lighting during germination was intentionally soft. The goal is not explosive growth but healthy establishment. Once these young plants are fully settled, they will be moved under the Future of Grow Black Series 600W full-spectrum LED, which will carry them through the rest of the cycle.
Like all plants in this project, this phenotype will be grown under a 12/12 light schedule from seed to harvest. It's a method I've documented for years and one I'll continue exploring throughout this diary. Every observation, success, challenge, and lesson learned will be documented as honestly as possible.
For now, everything is looking healthy, the seedlings have emerged successfully, and the journey of Blueberry Muffin Pheno B is officially underway.
Thank you to Zamnesia for the genetics and to Plagron for the substrate and nutrition supporting this run.
As always, thank you to everyone following along. I hope you'll enjoy the journey as much as I do documenting it.
Grower's Love! 🌱💚

DogDoctorOfficial Blueberry Muffin by Zamnesia | Pheno B 🍇🌱
Vegetative Week 1 | Finding Her Rhythm
Hello GrowDiaries family! 👋🌱
Welcome back to the journey of Blueberry Muffin Pheno B.
Last week we followed this seed through germination and into its first days above the soil. This week marks the beginning of vegetative growth as she settles into her final container and starts building the foundation that will support the entire cycle ahead.
As with all plants in this project, Pheno B is being grown under a 12/12 light schedule from seed. It is a somewhat unconventional approach, but one that allows us to document how different genetics and phenotypes respond when grown under flowering photoperiods from the very beginning of life.
While her sister has shown slightly faster development during these first days, Pheno B is taking things at her own pace—and that’s perfectly fine.
Every plant has its own rhythm.
⸻
Moving Into The Final Container
This week we transplanted Pheno B into her final home.
Rather than gradually increasing pot sizes throughout the grow, we prefer to place these plants directly into their finishing containers from the beginning.
The reasoning is simple.
Since this project is being run under 12/12 from seed, we want root development to begin immediately without interruptions from additional transplants later in the cycle.
The objective is to allow the roots to fully colonize the container while minimizing stress and maximizing consistency.
At this stage, healthy roots are far more important than rapid growth above the soil.
⸻
Building Foundations With Lightmix
For this run we are using Plagron Lightmix as the base substrate.
Lightmix offers a gentle starting environment while still providing enough nutrition to support young plants during their first days of life.
The goal during this stage is not explosive growth.
The goal is balance.
A healthy root zone, stable moisture levels, and a comfortable environment create the conditions needed for strong development later on.
⸻
Water First, Nutrition Second
The first irrigation after transplant consisted of plain water only.
Young seedlings still rely heavily on the energy reserves stored inside the seed itself, and Lightmix already contains enough nutrition to support those early stages.
After several days of establishment, we introduced a very gentle feeding schedule consisting of:
🌱 Terra Grow
🌱 Pure Zym
🌱 Power Roots
🌱 Sugar Royal
All products were used at light dosages with the objective of supporting root development and encouraging healthy growth without overwhelming a young seedling.
At this stage patience is still one of the most valuable inputs a grower can provide.
⸻
Light Intensity & Daily Light Integral
One aspect that often surprises growers when following these diaries is the light intensity being used this early.
Pheno B is already receiving approximately 350 PPFD.
Under a traditional vegetative schedule of 18 or more hours, this could be considered relatively strong for a seedling.
However, because these plants receive only 12 hours of light each day, the total amount of light accumulated throughout the day—the Daily Light Integral (DLI)—remains significantly lower.
By introducing moderate PPFD levels early, we help the plants adapt to stronger light while maintaining an appropriate daily light load.
The objective is adaptation rather than acceleration.
⸻
Environmental Conditions
Environmental conditions remained stable throughout the week:
🌡️ Day temperature: 27°C
🌙 Night temperature: approximately 25°C
💧 Relative humidity: 55%
🌱 Substrate temperature: 21°C
💧 Solution temperature: 21°C
🌿 CO₂: approximately 600 ppm
Consistency remains one of the most important factors during seedling establishment, and so far the environment has remained exactly where we want it.
⸻
Early Observations
Pheno B is already showing subtle differences compared to her sister.
Growth has been slightly slower and the overall structure remains a little more compact at this stage.
Leaf development is progressing well, but she appears to be taking a more measured approach to growth compared to Pheno A.
This is exactly why both phenotypes are being documented separately.
The differences may seem small now, but often these early observations become some of the most interesting comparisons later in the cycle.
For now, she appears healthy, stable, and comfortable in her new environment.
And that’s exactly what we want to see.
⸻
Looking Ahead
The root system is expanding.
The feeding program has begun.
The environment remains stable.
And now we wait.
Over the next week we expect to see increased vegetative growth, larger leaves, stronger branching development, and perhaps even more clues about the unique personality of this phenotype.
The race is not won during the first week.
Right now we’re simply laying the foundations.
And Pheno B is doing exactly that.
⸻
Thank You
A huge thank you to Zamnesia for providing the Blueberry Muffin genetics for this project.
Thank you to Plagron for the nutrition and substrate supporting this run.
And thank you to Future of Grow, and everyone following along and sharing this journey with us.
As always, thank you for stopping by.
The adventure has only just begun.
Grower’s Love everyone. 🌱💚🍇

DogDoctorOfficial Week 2 - Blueberry Muffin (Pheno B) ?🌱
Hello everyone, and welcome back to another update from the 8×8 Adventure!
For anyone joining the journey for the first time, this run follows multiple Zamnesia cultivars and phenotypes grown side-by-side under a 12/12-from-seed schedule. Each phenotype receives its own dedicated diary so we can document individual development, compare expressions, and observe how different plants reveal their genetics from seed to harvest.
By documenting Pheno A and Pheno B separately, we can follow each plant’s individual story rather than averaging them together. Sometimes the differences are subtle, and sometimes they are impossible to ignore.
This project is also being conducted under a 12/12-from-seed schedule. Rather than using a traditional vegetative period, the plants receive 12 hours of light and 12 hours of darkness from the very beginning. The objective isn’t to grow the largest plants possible, but to efficiently explore genetics, phenotype expression, structure, vigor, and flowering characteristics while maintaining a manageable garden.
Week 2 Overview
The second week has brought fantastic progress throughout the entire room. The seedlings are now firmly establishing themselves and beginning the transition into young vegetative plants.
PPFD has been increased to approximately 370 µmol/m²/s, providing more energy as the plants become capable of handling stronger light levels. Environmental conditions have remained stable throughout the week, with daytime temperatures around 27°C, nighttime temperatures around 25°C, and relative humidity maintained near 55% with the help of a humidifier.
Watering remains intentionally conservative at this stage. Each plant received approximately 250 ml on Day 8 and another 250 ml on Day 11. Nutrient levels have also been increased gradually throughout the week as the plants continue responding positively.
We finished the week at approximately:
• EC: 0.9 mS/cm
• pH: 6.0
Current feeding schedule:
• Terra Grow – 1.8 ml/L
• Pure Zym – 1 ml/L
• Power Roots – 1 ml/L
• Sugar Royal – 1 ml/L
The increase in nutrition has been introduced slowly and carefully, allowing the plants to adapt while monitoring their response. So far, the garden has reacted extremely well, showing healthy color, strong development, and excellent vigor.
Blueberry Muffin Pheno B
If there is one plant that has captured my curiosity so far, it is definitely this one.
From the beginning, Pheno B has been determined to do things her own way.
While many of her sisters have followed a more traditional development pattern, this phenotype continues producing unusual leaf shapes and quirky growth traits that immediately catch the eye. Several leaves display irregular morphology, and some of the foliage even carries what can only be described as a camouflage-like appearance, with multiple shades of green appearing across the same leaf surface.
It’s unusual.
It’s a little strange.
And honestly, it’s pretty fascinating.
What makes this phenotype particularly interesting is that despite all of these unusual characteristics, she simply refuses to slow down.
New leaves continue to emerge.
New nodes continue to form.
Growth continues moving forward.
The newest growth remains healthy, vibrant, and full of energy.
This isn’t a plant struggling to survive. This is a plant expressing itself differently while continuing to grow with confidence.
At this stage there is absolutely no reason to give up on her. Quite the opposite.
Phenotype hunting is often about discovering the unexpected, and plants like this are part of what makes growing from seed so rewarding. Sometimes unusual seedlings grow out of their quirks completely. Sometimes they keep those unique characteristics throughout their entire life cycle. And occasionally those odd traits become part of what makes a phenotype truly memorable.
For now, we’re simply observing, learning, and enjoying the journey.
Development Notes
During Week 2, Pheno B continued stacking nodes and expanding her canopy despite her unconventional appearance.
Five-finger leaves have begun appearing, growth remains steady, and the overall color is healthy throughout the plant. The root system continues developing beneath the surface while the plant gradually builds structure above it.
Every day brings something slightly different with this phenotype, and that’s exactly what makes her one of the most interesting plants in the room right now.
Mr. Baggy Report
Mr. Baggy remains on-site and fully committed to supervisory duties throughout the 8×8 Adventure.
His responsibilities currently include quality control inspections, environmental monitoring, motivational support, and posing for photographs whenever required.
Performance reviews remain ongoing.
Looking Ahead
The coming week should tell us much more about where this phenotype is heading.
Key observations will include:
• Continued leaf development
• Whether newer growth begins normalizing
• Additional branching development
• Stem strengthening
• Overall vigor and growth rate
• Further phenotype-specific traits
Week 3 is often where young plants begin revealing more of their genetic personality, and this Blueberry Muffin is already giving us plenty of reasons to stay curious.
Final Thoughts
Week 2 leaves me feeling very optimistic about this unusual little plant.
Yes, the leaf morphology remains different.
Yes, she continues showing some wonderfully strange characteristics.
But she is healthy.
She is growing.
And she is making this phenotype hunt far more interesting.
Sometimes the plants that stand out the most early on end up becoming the ones you remember long after harvest.
We’ll have to wait and see what story she decides to tell.
A huge thank you to everyone following along, commenting, sharing advice, and supporting the project.
Special thanks to Zamnesia, Plagron, Future of Grow, and everyone helping make this journey possible.
Most importantly, thank you to the entire growing community for continuing to share knowledge, encouragement, and passion for the plant.
Thank you for stopping by, and I’ll see you all next week for another update from the 8×8 Adventure.
Growers Love

The Beautiful Oddball
Welcome back to another week of the 8×8 Adventure, where twelve cultivars are being documented individually under a 12/12-from-seed schedule. Every phenotype receives its own dedicated diary, allowing us to follow each plant’s journey independently and observe how unique expressions emerge even between sisters sharing the same genetics.
This week brought one of the largest environmental adjustments of the entire project so far.
The lighting intensity was increased significantly, moving from approximately 370 µmol/m²/s PPFD to 700 µmol/m²/s PPFD at canopy level. Alongside the increase in light, nutrient strength and water consumption also rose to support the accelerating growth rate.
The response throughout the room has been overwhelmingly positive.
Growth has accelerated, internodes remain compact, and the plants appear eager for more.
⸻
Week 3 Environment
🌡️ Temperature: 27.4°C
💧 Relative Humidity: 55%
💡 PPFD: ~700 µmol/m²/s

Blueberry Muffin Pheno B
While her sister has spent the last week showing near textbook development, Pheno B continues to be the plant that makes me stop, smile, and ask questions.
Not because she is perfect.
Because she isn’t.
And that is exactly why I like her.
From the beginning this phenotype has carried a slightly unusual appearance. Certain leaves developed differently, growth patterns occasionally looked a little unconventional, and she never quite followed the same path as her sister.
Yet despite all those quirks, she continues moving forward.
Week after week.
Healthy.
Steady.
Determined.
Looking at her now, it is clear that she is gradually growing out of many of those early abnormalities. New growth is arriving cleaner, stronger, and more structured than before. The center of the plant is becoming increasingly organized, with fresh leaves stacking tightly around the apical growth tip.
She remains slightly smaller than Pheno A, but she is far from struggling.
In fact, she appears to be finding her rhythm.
The canopy has expanded noticeably during the week, internodal spacing remains compact, and the plant is beginning to develop a stronger framework that should support future growth.
One of the most interesting observations is how the newer leaves continue to improve with every passing node. The plant seems to be correcting itself naturally, producing increasingly normal foliage as it matures.
It’s almost as if she needed a little extra time to figure out who she wanted to become.
And honestly, those are often the plants that end up teaching us the most.
While Pheno A currently wins the beauty contest, Pheno B wins the curiosity contest.
Every time I look at her, I want to see what she does next.
⸻
Measuring Light: Why We Use a Quantum Sensor
One of the biggest changes this week involved increasing PPFD levels throughout the room, so this feels like a good opportunity to talk about one of the most useful tools available to modern growers.
The Dr. Meter Quantum Sensor
To monitor light levels, I use the Dr. Meter Quantum Sensor, a tool designed specifically to measure Photosynthetic Photon Flux Density (PPFD).
Rather than measuring brightness the way our eyes perceive it, a quantum sensor measures the photons that plants can actually use for photosynthesis.
This is an important distinction.
Plants don’t care how bright a light looks to us.
They care about how many usable photons are reaching the leaf surface.
A quantum sensor allows growers to measure exactly that.
Instead of guessing whether a plant is receiving too little or too much light, we can collect real data and make informed decisions.
Why PPFD Matters
PPFD tells us how many photosynthetically active photons reach a square meter every second.
Measured in:
µmol/m²/s
This information helps answer important questions:
* Is the plant receiving enough light to maximize growth?
* Is the light intensity limiting development?
* Are we approaching levels that could cause stress?
* Can nutrient levels be increased safely alongside higher light intensity?
This week, measurements showed the plants were capable of handling significantly more light than they were receiving previously.
That gave us confidence to increase intensity from approximately 370 PPFD to 700 PPFD, while simultaneously increasing nutrient strength.
The plants responded immediately with stronger growth and improved vigor.
This is one of the biggest advantages of using a quantum sensor.
Instead of guessing.
We measure.
Then we adjust.
And finally we observe how the plant responds.
⸻
Looking Ahead
The coming week should reveal even more about Pheno B’s personality.
Key areas of interest include:
* Continued normalization of new growth
* Branch development
* Structural differences compared to Pheno A
* Response to increased PPFD
* Overall vigor and growth rate
She may not be the largest plant in the room.
She may not be the prettiest.
But she is quickly becoming one of the most interesting.
And sometimes the plants that don’t follow the script end up writing the best chapters.
⸻
Thank You
A huge thank you to everyone following this adventure and supporting these diaries.
Thank you to the entire GrowDiaries community for creating a space where growers can learn, experiment, and share knowledge together.
Thank you to Plagron for providing the nutrition and cultivation support behind this project.
Thank you to Zamnesia for the genetics, equipment, and opportunity to document these cultivars from seed to harvest.
And thank you to every grower, reader, supporter, and fellow plant enthusiast who takes a moment to stop by, leave a comment, ask a question, or simply follow along.
The journey continues.
🌱💚?
Growers Love and see you next week, little oddball. I can’t wait to see what you do next.

DogDoctorOfficial Blueberry Muffin – Pheno B | Week 4
Finding Her Own Rhythm
Welcome back to another chapter of the 8×8 Adventure, where twelve cultivars are being documented individually from seed to harvest under a strict 12/12-from-seed schedule. Every phenotype follows its own diary, allowing each plant to develop independently and reveal the subtle differences that make every seed a unique expression of its genetics.
Week 4 has been another exciting chapter across the entire room.
The explosive growth that began last week has continued, and every day the garden feels a little more alive. Canopies are becoming denser, branches are reaching outward with confidence, and the room is slowly transforming into the miniature forest I imagined when this project first began.
One thing that couldn’t go unnoticed this week was the environmental reading.
33.3°C and 63% humidity.
Apparently the grow room has developed a strange obsession with the number three. 😄
Although temperatures climbed higher than I’d normally like, the relatively high humidity helped soften the impact, and the plants rewarded the stable environment by continuing to grow with impressive vigor. Sometimes nature reminds us that consistency is just as important as chasing perfect numbers.
⸻
Week 4 Environment
🌡️ Temperature: 33.3°C
💧 Relative Humidity: 63%
💡 PPFD: 700–800 µmol/m²/s
🌱 Medium: Plagron Lightmix
? Growing Method: 12/12 From Seed
As the room continues to develop, another interesting difference is appearing naturally.
The lighting itself hasn’t been increased significantly this week. Instead, some phenotypes are simply growing faster and moving closer to the fixtures. Those taller plants are now receiving around 800 PPFD, while the shorter individuals remain closer to 700 PPFD.
It’s another reminder that no two phenotypes read the same instruction manual.
Even under identical conditions, every plant follows its own pace.
⸻
Feeding Strategy
The feeding program has also continued evolving alongside the plants.
During the first weeks the nutrient solution stayed around pH 5.8, maximizing nutrient availability while young root systems became established inside the containers.
Now those root systems have expanded considerably, allowing a slight shift in strategy.
Throughout this week the solution gradually moved toward pH 6.1, while nutrient strength steadily increased, finishing around EC 1.8.
The recipe itself hasn’t changed dramatically.
No major adjustments.
No sudden jumps.
Simply a gentle increase in concentration to match the plants’ increasing appetite. Sometimes the smallest adjustments create the biggest improvements, and this week’s growth has been a great example of that philosophy.
Allowing the pH to drift slightly higher also gives the roots access to a broader spectrum of nutrients available within the substrate, helping support the increasing demands of this new stage of growth.
As always, the goal remains the same:
Listen to the plants, not the feeding chart.
⸻
Blueberry Muffin – Pheno B
This young lady has been quietly writing one of my favourite stories inside the tent.
Unlike her sister, who seemed determined to impress from almost the very beginning, Pheno B decided to keep everyone guessing.
Her first weeks were… let’s call them creative.
The leaf structure wasn’t quite what I expected, growth was a little unusual, and every new set of leaves felt like another clue in a mystery I hadn’t solved yet.
Fast forward to Week 4…
The mystery is starting to make sense.
She’s finding her own rhythm.
Looking at her now, it’s hard not to appreciate just how much progress she’s made over the course of a single week. The unusual appearance that once caught my attention is fading into the background as healthy, vigorous new growth begins taking over the canopy.
She’s still not trying to imitate her sister—and honestly, I hope she never does.
Every phenotype deserves to express itself.
The structure is becoming noticeably fuller, with side branches beginning to establish themselves beneath the canopy while the main stem continues building upward with confidence. Internodal spacing remains compact, creating a nicely stacked framework that should provide plenty of future flowering sites.
One detail I particularly enjoy is the contrast between the older and newer growth.
Fresh leaves emerge in a bright lime-green colour full of energy before gradually darkening as they mature, giving the plant a vibrant appearance that changes almost daily.
Looking deeper into the canopy, more secondary shoots are beginning to appear than I expected only a week ago. She seems to be quietly building herself from the inside out, strengthening her framework before making any dramatic moves upward.
There’s something very satisfying about watching a plant overcome an uncertain beginning.
She may not possess the textbook symmetry of Pheno A, but she’s developing a character entirely her own.
And sometimes, those are the phenotypes that end up becoming unforgettable.
⸻
Looking Ahead
Week 5 should be another exciting milestone.
With nutrient demand increasing, root development well established, and the first signs of flowering beginning to appear throughout the room, I’m expecting another noticeable leap in development.
Over the coming week I’ll be watching closely for:
• Stretch progression as flowering begins.
• Continued branch development.
• Response to the higher EC.
• Structural differences compared to her sister phenotype.
• How her unique architecture evolves as the canopy continues to fill.
The slow start now feels like a distant memory.
This week wasn’t about catching up anymore.
It was about proving that she has every intention of writing her own story.
⸻
Thank You
A huge thank you to everyone following this 8×8 Adventure and taking the time to visit these weekly updates.
Thank you to the entire GrowDiaries community for providing a place where growers from around the world can learn, share experiences, and inspire one another every single day.

DogDoctorOfficial ? Blueberry Muffin – Pheno B
Week 5 | Letting the Plant Choose Her Own Pace
One of the reasons I love growing multiple phenotypes from the same seed pack is that they constantly remind me of one important lesson…
Genetics always have the final word.
Even when plants share the same parents, the same environment, the same nutrition and exactly the same lighting schedule, each one develops its own personality.
Blueberry Muffin Pheno B is proving exactly that.
While her sister is already comfortably stepping into flowering, this lady is taking her time, continuing to build structure before fully committing to bloom.
And honestly…
I’m perfectly happy to let her decide.
⸻
🌱 The 12/12 From Seed Journey
For anyone joining this diary for the first time, welcome!
This entire project is being grown using the 12/12 from seed method, meaning the lighting schedule has remained at 12 hours of light and 12 hours of darkness from the very beginning of the grow.
Unlike traditional cultivation, where growers decide exactly when flowering begins by changing the light cycle, this method leaves much of that decision to the plant itself.
Each phenotype transitions when its genetics decide the moment is right.
That’s exactly what we’re seeing here.
Although the first pre-flower signs are beginning to appear, I still consider this another week of vegetative growth.
She simply hasn’t committed enough to flowering for me to officially change the diary yet.
It’s a perfect example of how two sisters can follow completely different timelines while growing side by side.
⸻
🌿 Building Structure Before Flowers
Rather than rushing her into bloom, this week focused on preparing the strongest possible foundation.
Pheno B naturally grows with an extremely compact structure, producing very short internodal spacing and dense foliage.
That beautiful compactness comes with one small challenge…
Light struggles to reach the interior of the canopy.
To help with that, I spent the week using gentle Low Stress Training together with regular leaf tucking to expose developing shoots hidden beneath the large fan leaves.
Toward the end of the week I also performed a very light defoliation.
Nothing aggressive.
Just removing a few carefully selected leaves to improve airflow and allow more light to reach the inner branches.
Sometimes less really is more.
By the end of the week the results were already becoming visible, with several lower shoots responding by stretching upward and beginning to develop into future flowering branches.
Exactly the response I was hoping for.
⸻
💧 Hand Feeding Continues
Unlike her sister, Pheno B remains completely hand-watered.
For now I want full control over how she receives her nutrients while continuing to observe how this phenotype develops naturally.
Hand watering also allows me to monitor her appetite closely and make adjustments whenever necessary based on her individual needs rather than following the same routine as the AutoPot system.
As always, every plant earns its own management strategy.
⸻
🍽️ Feeding
This week’s feeding consisted of the complete Plagron program, including:
• Terra Grow – 1.8 ml/L
• Terra Bloom – 1.8 ml/L
• Pure Zym – 1 ml/L
• Sugar Royal – 1 ml/L
• Power Roots – 1 ml/L
• Power Buds – 1 ml/L
The introduction of Terra Bloom and Power Buds marks another exciting milestone as the plant slowly begins preparing for reproductive growth.
Although she’s still spending most of her energy building structure, it’s the perfect moment to begin supporting what’s coming next.
Solution parameters remained stable with an EC around 1.78 mS/cm and a pH of approximately 6.02, providing a balanced nutrient profile while keeping the root zone healthy.
⸻
🌡️ Environment
The room continues running under intentionally warm conditions.
Day temperatures averaged around 31.1°C, nighttime temperatures remained close to 25°C, relative humidity stayed around 72%, and atmospheric CO₂ measured approximately 693 ppm.
Those humidity levels are still intentional.
At this stage I’m encouraging vigorous vegetative expansion and allowing the plants to establish as much healthy biomass as possible before gradually reducing humidity later in flowering.
It’s all part of preparing for healthier flowers in the weeks ahead.
⸻
📸 This Week Behind the Lens
This week’s photographs beautifully capture the personality of Pheno B.
She’s noticeably shorter than her sister, yet incredibly dense.
The studio side profiles reveal a stocky plant packed with tightly spaced growth sites, while the bird’s-eye photographs highlight just how compact her canopy has become.
Several close-up images also document the early effects of leaf tucking and the gentle defoliation, showing new shoots beginning to emerge from areas that were previously hidden beneath large fan leaves.
Watching those branches respond over only a few days is one of those quiet victories that makes plant training so rewarding.
⸻
🔍 Looking Ahead
Next week should answer one of the biggest questions of this grow.
Will Pheno B finally commit fully to flowering?
Or will she continue investing another week into structure before stretching?
Either outcome is perfectly welcome.
If she continues vegetative growth, I’ll maintain gentle training and keep opening the canopy to encourage even more secondary branching.
If flowering officially begins, the focus will shift toward supporting the stretch while maintaining an open, evenly lit canopy.
Whatever she decides…
I’ll simply help her become the best version of herself.

DogDoctorOfficial Blueberry Muffin – Pheno B
Week 6 | Nature Keeps Her Own Calendar
Growing multiple phenotypes from the same seed pack is one of the greatest reminders that every plant writes her own story.
Even when everything is identical—the same room, the same lighting schedule, the same nutrients, the same environment—each phenotype responds according to its own genetic blueprint.
Blueberry Muffin Pheno B continues to prove that point beautifully.
While her sister has already settled comfortably into flowering, this lady is still taking her time. She's showing the earliest signs that bloom is approaching, but she hasn't fully committed just yet.
And that's perfectly okay.
Sometimes the best thing a grower can do is stop trying to rush nature and simply pay attention to what the plant is saying.
🌱 The 12/12 From Seed Adventure
If you're joining this diary for the first time, welcome!
This entire 8×8 Adventure is being grown using the 12/12 from seed method. From the moment these seeds germinated, they've received twelve hours of light and twelve hours of darkness every single day.
Unlike a traditional photoperiod grow, where the grower decides exactly when flowering begins by changing the light cycle, this approach allows each plant to determine its own timing.
That's why these two Blueberry Muffin sisters look so different despite growing side by side.
Pheno A embraced flowering weeks ago.
Pheno B is still finishing the work she wants to do before making that transition.
She's reminding us that genetics don't own a calendar.
They simply follow their own rhythm.
🌿 A Compact Bush With Big Potential
One thing that immediately stands out this week is just how compact this phenotype has become.
She's noticeably shorter than her sister, yet every internode is packed tightly together, producing a dense, healthy canopy filled with future flowering sites.
The gentle Low Stress Training continues to work exactly as intended.
Rather than forcing dramatic changes, it has gradually opened the plant while encouraging side branches to grow upward and compete for the canopy.
Leaf tucking has remained part of the daily routine, helping expose developing shoots without removing unnecessary foliage.
With such tight growth, every little adjustment makes a noticeable difference.
The result is a beautifully balanced little bush that feels full of potential.
💧 Individual Care for an Individual Plant
One advantage of growing each phenotype as its own diary is being able to treat every plant according to its own needs.
Unlike several of the other girls in this room, Pheno B is still being hand-watered.
She continues receiving her own feeding schedule, allowing me to make adjustments specifically for this phenotype while observing how she develops before eventually joining the rest of the flowering program.
Not every plant wants the same meal at the same time.
Listening to that difference is part of becoming a better grower.
🍽️ Feeding
While many of the flowering plants have already moved to a bloom-focused nutrition schedule, Pheno B continues following a transitional feeding program that supports both vegetative growth and the approaching flowering stretch.
This week's feeding consisted of:
• Terra Grow – 1.8 ml/L
• Terra Bloom – 1.8 ml/L
• Pure Zym – 1 ml/L
• Sugar Royal – 1 ml/L
• Power Roots – 1 ml/L
• Power Buds – 1 ml/L
The nutrient solution remained stable with an EC of approximately 1.78 mS/cm and a pH adjusted to 6.02, providing everything she needs while allowing her to continue developing at her own pace.
For now, there's no reason to rush any changes.
Healthy plants tell you when they're ready.
🌡️ Environment
Environmental conditions remained very consistent throughout the week.
Daytime temperatures averaged around 29°C, with nighttime temperatures close to 25°C. Relative humidity settled around 60%, while atmospheric CO₂ measured approximately 693 ppm.
These stable conditions continue providing an ideal environment for steady growth, allowing Pheno B to focus her energy on building structure before fully committing to flower.
Consistency is often one of the most overlooked nutrients in any grow room.
📸 This Week Behind the Lens
This week's photographs perfectly capture the personality of this phenotype.
The side profiles reveal an incredibly stocky plant with thick stems and remarkably tight internodal spacing, while the close-up images begin showing the earliest hints of floral development hiding between vibrant green leaves.
She's not stretching dramatically.
Instead, she's quietly building a strong, compact framework that could eventually support some beautifully dense flowers.
Sometimes the plants that make us wait the longest surprise us the most at harvest.
🔍 Looking Ahead
I have a feeling this could be Pheno B's final week of vegetative growth.
The first signs are there.
She's beginning to hint that flowering is finally approaching, even if she's still taking things more slowly than the rest of the room.
Over the coming week I'll continue with gentle leaf tucking, maintain the current feeding program, and simply let her dictate the pace.
If she officially enters flower, the diary will naturally follow her into that next chapter.
If she chooses to wait another few days...
That's perfectly fine too.
After all, one of the biggest lessons this project continues to teach is that plants don't grow according to our expectations.
They grow according to their genetics.
