Cream&Cheese CBD/Kosher Kush -RSO-ES300

Beginning of the week Feb10 D50 Light at 240w Flipped to 12/12 about 4 days ago. Actual problem (I think) is P toxicity. Leading to zinc and iron def. Measured my runoff and its 7.3 ish. Far too high. I water regularly at 6.0 and let a runoff that I dump. With the flo cycle started, I expect the plants absorb more P, reduce PH and fix the deficiencies... That's the plan. Plants seems to get better, slowly but surely. Watered at low ph all week and reduced the runoff at 6.8-7
