ok, i read somewhere yesterday on this forum that iron chelate cannot be mixed with KPO4. is this true? if so, it may explain alot of my problems as i mixed my KNO3, KPO4, and CSM+B together in one solution. i'm dosing 150% EI but the plants don't look as good as i would expect and i'm having trouble with gsa, gda, and hair algae. please advise.
