Blueberry Muffin – Pheno B
Week 7 | Finally Joining the Flower Party
Welcome back to another week of the 8×8 Adventure! 💚🌱
If this is your first visit to the diary, welcome!
This project follows twelve different cultivars growing together under exactly the same environment, lighting, irrigation and nutrition. Every plant receives the same care, allowing genetics to become the true variable. It has been incredible watching each cultivar—and even different phenotypes of the same strain—express their own unique personality.
Blueberry Muffin Pheno B continues her journey under a strict 12/12 light schedule from seed beneath the Future of Grow Black Series LED. After taking her time compared to the rest of the room, this week she finally decided it was time to move forward.
Sometimes patience is rewarded.
And this week, she certainly rewarded it.

🌸 Flower Development
This is the week I'm officially considering her first week of flowering.
Although we're already seven weeks from seed, this phenotype followed her own schedule from the very beginning. While the rest of the room has been well into flower for some time, she spent longer building her structure before making the transition.
The exciting part is just how quickly she has responded once flowering began.
Fresh white pistils are now appearing everywhere, the tops are becoming much more defined, and every day she seems a little more committed to producing flowers.
She may have arrived late...
...but she's certainly not wasting any time now.

🌿 From Slow Starter to Fast Mover
One of the biggest changes this week is her overall appearance.
The lighter colour from previous weeks has completely disappeared, and she now carries a rich, healthy green from top to bottom. The foliage looks vibrant, balanced and full of energy, with no signs of nutritional deficiencies.
Seeing that transformation is incredibly satisfying.
It confirms that sometimes all a plant really needs is time.
For several weeks she was easily one of the slowest plants in the room, but once she decided to flower, her pace changed dramatically.
It's almost as though she's trying to catch up with her sisters.

🌱 Structure & Personality
Pheno B continues showing a very different personality compared to her sister.
Both plants are actually quite similar in height, but that's where the similarities begin to fade.
While Pheno A developed a more open structure, Pheno B has become much bushier and denser, producing a compact canopy with very tight internodal spacing.
The Low Stress Training carried out during vegetative growth has created a beautiful, even framework, allowing multiple flowering sites to receive excellent light exposure despite her naturally dense growth habit.
She's not trying to become the tallest plant in the room.
She's becoming one of the fullest.
It will be fascinating to see how this compact structure influences bud development over the coming weeks.

🌡️ Environment
Environmental conditions remained stable throughout the week, providing ideal conditions for this important transition into flowering.
🌡️ Day temperature: 29°C
🌙 Night temperature: 25°C
💧 Relative humidity: 60%
🥥 Root zone temperature: 21°C
💦 Nutrient solution temperature: 24°C
⚗️ pH: 5.8
⚡ EC: 1.95 mS/cm
💨 CO₂: 693 ppm
💡 Light schedule: 12/12
Keeping these conditions stable allows each phenotype to express its own genetic potential without unnecessary environmental stress.

🌱 Feeding
As flowering begins, her feeding programme has now moved forward alongside the rest of the room.
This week's nutrient solution consisted of:
Plagron Terra Bloom – 2 ml/L
Plagron Sugar Royal – 1 ml/L
Plagron Pure Zym – 1 ml/L
Plagron Power Buds – 1 ml/L
pH adjusted to 5.8
The richer green foliage and healthy new growth suggest she's very comfortable with the current feeding schedule, and I'll continue monitoring her closely as flower production accelerates.

📸 Behind the Lens
This week's photographs capture a plant that finally seems confident about the direction she's taking.
The close-up shots show clusters of bright white pistils emerging from every growing tip, while the wider photographs reveal just how compact and symmetrical her structure has become.
One thing that immediately stands out is the colour.
Compared to previous weeks, the foliage is noticeably healthier, richer and more vibrant.
She may have been quiet for the first part of this adventure...
...but she's beginning to steal a little attention now.
────────────────────────────
🔍 Looking Ahead
Now that flowering has officially begun, I'm excited to see how this phenotype develops over the next few weeks.
Will she remain compact and produce dense, chunky flowers?
Or will she surprise us with a stronger flowering stretch before settling into bud production?
That's one of the reasons I love documenting different phenotypes.
Even sisters can tell completely different stories.
Whatever happens next, she'll decide the pace—and I'll simply continue giving her everything she needs to become the best version of herself.

💚 Thank You
Thank you so much to everyone following this 8×8 Adventure.
Every week these diaries remind me that growing isn't just about harvesting beautiful flowers. It's about observing, learning and appreciating the incredible diversity that exists within genetics.
A huge thank you to GrowDiaries for providing a place where growers from around the world can document every lesson and share their experiences with such an amazing community.
Thank you to Zamnesia for these wonderful Blueberry Muffin genetics. Watching two sister phenotypes develop into such different plants has been one of the highlights of this project.
Thank you to Plagron for providing the nutrition that supports every stage of this grow and helps these plants express their full potential.
And thank you to Future of Grow LED for delivering the consistent lighting that powers this entire 8×8 Adventure from seed to harvest.
Finally, thank you to everyone reading, commenting and following along.
Your support makes documenting this journey even more rewarding, and I hope these diaries continue helping and inspiring growers everywhere.
Growers Love, and I'll see you all next week as Blueberry Muffin Pheno B continues writing her own unique story. 💚🌱
