What's up guys, got a little riddle hear going on and wondering what it could be. My initial thought is Phosphorous Deficiency. Growing out of Fox Farm soil, added dry amendments topping with an occasional liquid kelp feed. Soils pH is now at 6.3 (just measured her) I also moved the fan away from these guys and pointed it 5 inches above these ladies, it was at about an inch or two above them. (wind burn?) I water half a gallon every third day to the 7 gallon pots. (sometimes every 2nd day) Any ideas as to what's causing the burn from the inside to outside?
