Does anyone have any insight? If some of you are looking for my system stats, they are the same as they have always been. E&F with 4" net pots, 1" rockwool cube surrounded by hydroton. Currently feeding tap water at 350 PPM plus 200 PPM of PBP Grow. Water temp around 68°, air temps around 78°. CFL's for lighting. Fans galore and plenty of exhaust and intake. Someone's gotta be able to tell me something!
