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.
A special thank you to Plagron for providing the nutrients and cultivation support that keep this project moving forward.
Thank you to Zamnesia for the incredible genetics, equipment, and the opportunity to document each phenotype from seed to harvest.

What an adventure guys, we got to the end without even realizing it, as a famous Italian politician would say "they didn't see me coming", the F1 Hybrids can play this trick, they get to the end without you even realizing it.
They are damned, indeed blessedly faster, it is the flower that forms more quickly, it goes from hairs, to small buds, to mature buds in a truly record time. One plant finished in 59 days and the other in 65, and we are not talking about little grass produced, we are talking about at least 100 grams but also something more.
I tell you guys, try these F1s from Zamnesia, they are a rocket, as I was saying above of course you have to grow in ideal conditions or you have to try to get close to them, don't think of keeping the humidity at full blast during flowering and having good results. Don't think of overwatering and overfeeding and having good results. The plant must be observed, kept balanced and it is not easy at all. If you keep this balance, look at the color of the leaves and pay attention to the basic parameters, you will really harvest a lot of weed. Then if you want to grow as it comes, be careful, these plants are IDEAL FOR BEGINNERS. There is no better way to get easy, good and fast results than growing an F1 of Zamnesia.
The resin is 10 and praise, my gloves were full of charas from gloves in both harvests and smoked it is divine.
They were both harvested with the pistils more or less at 70% - 75% and the trichomes mixed: some amber, mostly cloudy and some transparent. Read the explanation of Zamnesia on instagram the best I have ever read if you want clarifications on the moment of harvest. My advice is NOT to let the plant go too far, maturity is fine but then the THC decays and even the Sativas become with physical effects. Therefore more mature on indicas and even a little less on sativas.
I can't wait to vape it.
Plagron's gruel gave us a lot of strength and vigor now we are simply in flsuh with Canna's product // Strain Description // If you were looking for a reliable, versatile and accessible strain, here it is. Blue Cheese F1 Automatic by Zamnesia Seeds uses F1 genetics to produce uniform, rewarding and easy-to-grow plants. This strain stays small, so you will have no problem finding a place to grow it. After just 10 weeks from seed, you can enjoy tasty buds with relaxing effects.

😘.Hello My Friends.. 😘
📰 ... March 4, 2021... 📰
🌿 Day N°31 🌿
We are in the middle of the 5th week of growth for my three Feminized Amnesiac from Spliff Seeds..🚬
The plants are beautiful, after two weeks under my lamp @TSW2000 from Marshydro, they look so cute.🍀
📰 March 2nd
I transplanted my plants into 3.4 liter pots with All-Mix soil from Biobizz.
I topped two Amnesiac and the third one is with LST. I could have done it sooner, but last week I was on vacation in the mountains.. 🏔️
I have a bit of experience with Topping, but the LST I never test. I hope I did everything well as it should and that the plant will react well.. 😷
💉 Nutrients 💉
I incorporated 16 grams of Easy-Boost granules from Royal Queen Seeds into 3.4 litres of Biobizz All-Mix soil.
🔦 Light 🔦
I increased the power of my #MarshydroTsw2000 from 25% to 40%.
🐛 PEST 🐜
The treatment by the leaves of TEC FORT last week (1ml/l) worked very well, on 14 plants I saw only one thrips. On the blue stripes there is nothing..💀
That's all for now my friends.
Take care of yourself and your loved ones.. 😷
I wish you only happiness with your plants.. 🌻
... 🕊️ PEACE & LOVE 🕊️ ...

Miss Kalini is doing super great, she's packing up a whole lot of thick, dense well reeking buds.
She became this nice bush that uses up half of the space in the tent.
I haven't given her nutrients for a couple off days and don't think I will get her back on them.

Hello my friends 😇
Purple Lemonade had been flush today !! She looks beautiful that purpul-dark buds are amazing. In next 3 or 4 days I will cut her 😇
Cinderella and Bruce Banner drinking less from a avg. 1.7l/day to 1.25l/day, so end of flowering for this two will be in around 2 weeks.
Cinderella looks really good, she should give a good harvest.
Update:
Day 67
Happy time !! Harvest time !! Finally Purple Lemonade get to the final point.
At this moment there is 0% of lemon scents, BUT !! There is a beautiful smell of berries, chocolate and leather in the air. I can't wait to try it
All the best, You Lovely Girls Growers 😇 💪 🙏

Connect TrolMaster components into the Tent-X system. Program DSP2E, Temperature DST2E, Humidity DSH2E, as well as the AMP3 sensor with PH and EC probes, are all in place.
After calibrating the probes, AMP3 module works perfectly! It has a quick response in measurements, is accurate, and I am very happy about the possibility of online monitoring of liquid values.
After day off use i can tell that all readings are very consistent, compared with Milwaukee, totally without all over the place measurements. Perfectly steady and on spot receding!
The Program device runs flawlessly all day, and I hope it has solved all the problems I had with DH48-S timers.
The humidity control operates without errors throughout the day, and it’s nice to see in the app when the module is active.
Raise light as much as i can..50-55cm from canopy. Set off misting time from 30min to 35min @ day time , and from 35min to 45min @ night time

Olá senhores da weed!!! Sorry atraso atualização mais essa quarentena tá atrapalhando um pouco, mudanças na configuração por conta do aumento da temperatura então decidi troca de dwc para coco, e assim evitar os problemas de podridão no Dwc a solução aumenta a temperatura e aumenta o risco de fungos nas raízes então hj com 48 dias elas estão bem grandes e tudo certo obrigado a todos que acompanha e comenta no meu post

End of week 6; Day 42
So far so good, Frost is setting in on the strawberry Gorilla. The cookies is stretching beyond belief and is about 55in tall from the floor up.
The strawberry has stayed shorter and bushier than the cookies. Smell is also coming pretty strong.
Happy Growing y'all

Day 48 - 11/11/19 started this week early by accident.
Plant smells like tropical cheese and i cant see the stalk anymore except from the leaves, very bushy and seems to be in a mid stage of flowering. buds are getting bigger by the looks of it. very sticky also!
Ive been removing about 2 leaves per day from this one, started with a couple touching the soil and removed a few higher ones today to expose the buds to more light and fresh air. when looking at this plant side on the main cola looks huge and growing more every day. im assuming this is about 2 weeks away from harvest so il probs flush next week. roll on harvest time! other than that the humidity has went up to 50-55 the odd time when watering all the plants. it doesnt stay high long with the heat from the lights so it should be fine.
Day 51 - 14/11/19
Still removing the odd couple of leaves every day to let the fresh air get near the main cola, i still cant see it very well but it looks like what a 6-7g bud looks like when its dried aha.
the smell can be described as if someone took a cheese strain and added something powerful and herbal/tropical to it.
cant wait to order my jewelers loupe in a few days to see where im really at :) and i added a video to show the plant looking all frosty. a few weeks to go now!

Into week 7 and all is good. All are in flower and swelling out very nicely. Ethos OG Kush is frosty and smells like a citrus grove. Barney's Purple is an absolute beast. Her stretch was impressive for an autoflower and she is almost 48in high. Her flowers are swelling nice and she has become much more fragrant in the last week. Fastbuds Zkittlez is frosty and swelling nice. She is also very fragrant, smelling like sweet candy. Seedsman Pink Kush CBD is doing well, beautiful dark purple flowers and leaves. Lights are still 18/6. No nutes. Monitoring trichomes daily looking for changes in color and clarity in preparation for harvest.
