This is a grow in Sunshiine #4, 5 and 7 gallon pots, 5'x7'x8' area, 2200w vented shaders in an otherwise sealed room. AN Sensi 2 + program as per AN nute calculator for veg, flipped to 12/12 and began AN connoisseur 2+ program Light Feeding on AN nute calc. Temps don't exceed 78F in veg (no CO2) and run about 84-86F in bloom with CO2 matching PPM in food. Humidity @ 50%, RO water always Ph'd between 6.2 and 6.4. The weekly reg is 1 feed, then 1 water with Sensi CalMg (and GE Seaweed Extract every other week), and one water with straight PH'd RO water. Each watering is just until runoff....hand watered.
Zero issues through veg. Growing Querkle, Sweet Pink GF, and Cotton Candy. About 10 days into 12/12 I noticed a few spots, and now on day 12 its getting worse. It only seems to be affecting the large fan leaves, and it hit the Querkle more than the others.....the pic is the MOST affected leaf. Plants are otherwise looking AMAZING.
TIA! Aloha
