Was out of town all week and came back to find the CBD Star in my space bucket not looking good. It looks like a phosphorus deficiency but not entirely sure. Yellow leaves with brown/black spots and dark red/purple stems. I flushed it with 2 gallons 6.5 pH water, re-fertilized, put it out in the sun and defoliated. I defoliated pretty heavily since many of the fan leaves were yellowed and blocking light from the lower bud sites. The center was also getting pretty dense so I carefully removed some of the leaves to help with airflow. Despite the stress, It seems to have bounced back reasonably well. There’s probably irreparable damage given the level of yellowing but the buds continue to grow and thicken. Cheese has absolutely exploded and looks great. It probably doubled in height last week with many bud sites on the 5 main stalks. Excited to see how it turns out.
