Grow Diary Blueberry

This week marked the first week of late flower for both Blueberry plants. By this point, bud weight had increased significantly, and I had to add structural support to every branch of Blueberry #1 - similar to what I did for Blueberry #2 back in Week 9.

Feeding continued a few times per week, but at a much lower strength than in mid-flower. I aimed to maintain EC levels in a healthy range, keeping nutrient concentrations between 800–1,000 ppm to support ripening without overloading the medium.

Mid-week, I performed a detailed trichome inspection to assess maturity. I took 2–3 macro images of each branch set, calculated the trichome distribution for each node, and used a weighted average to get a clear picture of overall progression for both plants. The results showed that both Blueberry plants were maturing at a similar rate, with an average trichome profile of 30% clear, 65% cloudy, and 5% amber. Individually,

By this stage, I had tapered UV-A exposure from its peak of 2 hours per day in mid-flower down to 60 minutes daily. I held steady at that duration throughout Week 11. Light intensity remained high across the canopy to keep pushing the sativa-leaning Stardawg, which continued to trail the Blueberry plants by a couple of weeks in terms of maturity.
