Whats up Kd. Got up to full strenght with the pure blend bloom, worked well no real side effects could be seen only good growth. Used that along with cal mag+ and as far as I know got pretty good results. Kd, not sure if this helps with your water but I let myne sit out overnight w/ or without nutes just heard it helped. Ph is something I was concerned about but not as much so as say in a hydro setup, I mean it seems once plants begin to " Go " theres not much that stops them. Those babys are gonna really fatten up for you from the looks. How many weeks in flow ar they? Started checkin on those trich's.
