Grow Diary Blueberry

This week marked the fourth week of mid-flower in my run. Light intensity hovered between 830–890 PPFD (36–38 DLI). I continued to push mid-flower nutrients at 1,200–1,400 ppm. As the plants will begin transitioning into late flower soon, I started dialing back UV-A exposure by a few minutes each day and gradually inching down light intensity.

A mid-week trichome assessment showed approximately 45% clear, 50% cloudy, and 5% amber heads.

After Stardawg #1 formed male flowers in early mid-flower, I began checking all plants every other day at minimum to ensure none of the others were exhibiting hermaphroditic traits.

In Week 9, I observed Blueberry #2 producing five to six male flowers on its lowest branches - possibly triggered by earlier nutrient imbalances, though the exact cause is uncertain. I swiftly removed all male flowers.

Also in Week 9, Blueberry #2 began leaning heavily under the weight of her buds. To correct her posture, I installed an AC Infinity trellis net above the canopy, wove the main colas of all plants through the grid, and gently tied each node of BB#2 back to the central stem with garden wire. This support stabilized her without stressing new growth.
