Blueberry Muffin – Pheno A
Week 7 | Every Plant Has Its Own Pace
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 conditions. Every plant shares the same environment, lighting, irrigation system, nutrient solution and care. The only real variable is genetics, making this a fascinating opportunity to observe how each cultivar expresses itself when everything else remains constant.
Blueberry Muffin Pheno A continues her journey under a strict 12/12 light schedule from seed, growing in a 15-litre AutoPot system beneath the Future of Grow Black Series LED, while being documented from germination through to harvest.
One of the biggest lessons this project continues to teach is that no two plants read the same script.
Some sprint ahead.
Others take their time.
Blueberry Muffin has clearly chosen the second option.

🌸 Flower Development
Flowering continues exactly as expected, although she remains one of the slower ladies in the room.
The initial stretch is beginning to settle, while clusters of bright white pistils continue appearing across every flowering site. Buds are slowly beginning to define themselves, and although they aren't stacking aggressively yet, there is no doubt she has fully committed her energy to reproduction.
At this stage I prefer to let the plants work without unnecessary interruptions.
During the first two or three weeks of flowering they're busy redirecting energy from vegetative growth into flower production. Unless a plant truly needs intervention, I find it's often better to simply observe, let nature do its work and avoid creating unnecessary stress.
Sometimes the best thing a grower can do...
...is nothing at all.

🌿 Slowly Finding Her Colour Again
Last week I mentioned that Blueberry Muffin was asking for a little more nutrition than some of her neighbours.
That continues to be the case.
She still isn't displaying the rich green colour I'd ultimately like to see, but the good news is that she's slowly responding. By the end of the week the foliage had noticeably improved, confirming that the adjustments are moving in the right direction.
One of the challenges of running a room like this is that every plant shares the same reservoir.
If this were a single-plant grow, I could tailor the nutrient solution specifically to her needs. But in a room containing twelve different genetics, the feeding programme has to serve the collective rather than the individual.
Fortunately, the entire room reached the point where nutrient demand naturally increased this week, so the reservoir was adjusted accordingly. The increase wasn't made specifically for Blueberry Muffin, but it should help her continue recovering alongside the rest of the garden.
Sometimes growing isn't about creating the perfect recipe for one plant.
It's about finding the best balance for all of them.

🌱 Structure & Personality
Although she remains relatively compact compared to some of the other cultivars, Blueberry Muffin continues developing a very attractive structure.
Her branches remain nicely spaced, the internodal distance is consistent, and light continues penetrating well throughout the canopy thanks to the gentle leaf management carried out during the vegetative stage.
She's certainly not trying to be the biggest plant in the room.
Instead, she's quietly building a neat framework that should support healthy flower development over the coming weeks.
Not every champion announces themselves early.
Some simply take a little longer to show what they're capable of.

🌡️ Environment
The flowering room continues running under stable conditions, allowing the plants to focus their energy on flower production.
🌡️ Day temperature: 29°C
🌙 Night temperature: 25°C
💧 Relative humidity: 60%
🥥 Root zone temperature: 21°C
💦 Nutrient solution temperature: 20.2°C
⚗️ pH: 5.8
⚡ EC: 1.95 mS/cm
💨 CO₂: 693 ppm
💡 Light schedule: 12/12
Consistency remains one of the greatest allies during early flowering, and maintaining a stable environment helps every cultivar express its genetic potential as evenly as possible.

🌱 Feeding
The AutoPot system continues delivering fresh nutrient solution whenever required, allowing the root zone to remain consistently supplied throughout flowering.
This week's reservoir consists 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 increase to 2 ml/L of Terra Bloom reflects the overall nutritional demand of the room as flowering progresses. Blueberry Muffin appears to be benefiting from this adjustment, and I'll continue watching her closely over the coming weeks to see if her foliage continues returning to a deeper green.

📸 Behind the Lens
This week's photographs tell a story of patience.
The flowers continue to develop steadily, fresh pistils cover every developing bud site, and the plant's elegant structure is becoming increasingly apparent.
Perhaps the most interesting detail captured through the lens is the gradual improvement in leaf colour. It's subtle, but visible enough to suggest that she's beginning to settle into her new feeding regime.
Photography often reveals progress that our eyes overlook during daily inspections.
Looking back at previous weeks reminds me just how much can change in only a few days.
────────────────────────────
🔍 Looking Ahead
Over the next week I'll simply continue monitoring her progress without making unnecessary adjustments.
I'm hoping to see the foliage continue regaining a richer green while the flowers begin putting more energy into stacking and bulking up.
Blueberry Muffin may be taking her time...
...but that's perfectly fine.
Every plant has its own rhythm, and one of the greatest lessons any grower can learn is knowing when to guide—and when to simply let the plant write its own story.

💚 Thank You
As always, thank you so much to everyone following this journey.
Whether you've been here since germination or have only recently discovered the diary, I truly appreciate every visit, every comment, every question and every shared experience. Watching these twelve cultivars grow side by side has become an incredible learning opportunity, and it's even more rewarding because it's shared with such an amazing community.
A huge thank you to GrowDiaries for providing a platform where growers from around the world can document their experiences and continue learning together.
To Zamnesia, thank you for the fantastic Blueberry Muffin genetics and for allowing us to explore how this cultivar expresses itself under a unique 12/12-from-seed approach.
To Plagron, thank you for providing the nutrients and growing media that support these plants through every stage of their journey.
And to Future of Grow LED, thank you for delivering the light that powers this entire project and helps every phenotype reveal its own unique character.
Finally, thank you for being part of this adventure.
Every photograph, every observation and every lesson becomes more meaningful because it's shared with this incredible community.
Growers Love, and I'll see you all next week as Blueberry Muffin continues finding her own pace through flower. 💚🌱
