THX man, also, I'm at the stage to up my nute levels, I'm following all the directions on the bottles properly, my math is right, but is it normal for my res water to change to the color of my nutes? I can't find anything about this on the net. Before i was putting low nute levels for the cuttings and the nutes always diluted and the water stayed clear, now with the higher amounts my water is the color of microgrow? Any help would be awesome
