🌱 Week 3 | Purple Haze Photo | Folder 7A | Building the Foundation, One Leaf at a Time
Welcome back to another chapter of Project Blue, where every Purple Haze phenotype receives its own dedicated GrowDiaries report. Although these plants all come from the same genetic line and are growing under identical conditions, each individual expresses its own personality, structure, and growth rhythm.
That is exactly why these diaries exist.
Some growers only document a room. I wanted to document every plant.
Each report is completely self-contained, allowing anyone who discovers this diary to understand the entire project without needing to read the previous folders.
Like every plant in Project Blue, Purple Haze 7A is being cultivated using my favourite 12/12 From Seed technique. From the moment she broke through the soil, she has lived under a 12-hour flowering photoperiod, encouraging compact growth, tight internodal spacing, and allowing each phenotype to reveal its natural characteristics while remaining perfectly manageable inside the grow room.
Even though we’re only entering Week 3, this little lady has already shown remarkable progress. Looking back at the first photographs of the week compared with the final ones, the transformation is easy to appreciate. She began the week looking modest and compact, but by the end she had developed into a beautifully structured young plant with noticeably stronger branching and a much fuller canopy.
Sometimes the biggest progress isn’t measured in height—it’s measured in structure.

🌡️ Week 3 Growing Environment
Consistency remains one of the most important ingredients in every successful grow.
Throughout the week the environment remained stable:
• 🌡️ Day Temperature: 27°C
• 🌙 Night Temperature: 25°C
• 💧 Relative Humidity: 55%
• 🌱 Root Zone Temperature: 21°C
• 🚰 Nutrient Solution Temperature: 20°C
• ⚖️ pH: 6.0
• ⚡ EC: 1.3
• 🌬️ CO₂: approximately 666 ppm
• 💡 Photoperiod: 12 Hours ON / 12 Hours OFF
• ☀️ Average PPFD: 600–700
Stable environmental conditions allow the plants to dedicate their energy to growth instead of constantly adapting to fluctuating temperatures or humidity levels. Healthy roots, consistent transpiration, and balanced metabolism all begin with a stable room.

🌿 Feeding Schedule
Purple Haze 7A continues receiving the complete Plagron Terra vegetative program:
• Terra Grow — 1.8 ml/L
• Power Roots — 1 ml/L
• Pure Zym — 1 ml/L
• Sugar Royal — 1 ml/L
At this stage I still prefer a conservative feeding strategy. Rather than pushing maximum growth, my objective is to build a healthy root system, strengthen the stems, and encourage vigorous but controlled vegetative development before flowering accelerates naturally.
A healthy plant never needs to be rushed.

🍃 Leaf Tucking Before Leaf Cutting
One of the biggest changes throughout this week wasn’t caused by nutrients or lighting—it came from simple canopy management.
Rather than removing fan leaves, I continued practicing leaf tucking, gently repositioning the larger leaves beneath developing branches whenever possible.
This simple technique allows light to reach lower growth sites without sacrificing the plant’s solar panels.
Those fan leaves are producing valuable energy every hour the lights are on, so if they can be moved instead of removed, the plant keeps all of that photosynthetic power while the lower branches receive the light they need to grow.
It’s a small adjustment that often produces surprisingly big results over time.
⸻
🌱 Gentle Low Stress Training
As the week progressed, Purple Haze 7A also became an excellent candidate for some very gentle Low Stress Training (LST).
Rather than forcing the plant into shape, the objective is simply to guide her natural growth.
By carefully opening the canopy and encouraging the developing side branches to receive equal exposure to the light, we’re already beginning to create a much more balanced structure for flowering.
The difference between the beginning and end of the week is remarkable.
Instead of one dominant growing tip, multiple future flowering sites are now waking up and preparing to compete for the canopy.
Every day she becomes a little more symmetrical.
Every day the structure becomes stronger.
And every day she looks a little more prepared for what’s coming next.

🌿 A Compact Plant With Big Potential
Purple Haze 7A may still be one of the smaller plants in the room, but she has something I always appreciate—balance.
Her internodal spacing remains tight.
The stem is thickening nicely.
The foliage displays a rich, healthy green colour.
New growth is vibrant and full of energy, while the secondary branches continue to develop steadily beneath the canopy.
She’s not trying to become the biggest plant.
She’s quietly becoming one of the best-built.
Very often, those are the plants that surprise you the most once flowering begins.

🔭 Looking Ahead
With another successful week behind her, Purple Haze 7A is entering the next stage with an increasingly well-organized structure and excellent overall health.
The combination of stable environmental conditions, gentle LST, strategic leaf tucking, and balanced nutrition is beginning to pay dividends. Every adjustment this week has been made with one goal in mind: creating an even canopy that will maximize light distribution once flowering starts to accelerate.
She’s still a compact young lady—but she’s no longer a tiny seedling.
She’s becoming a very promising phenotype.
Growers Love ad I can’t wait to see what she has planned for the weeks ahead.
