? 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.
