Week 3 into flower on my fast eddy auto I noticed mag deficiency on lower leaves. Did some reading and learned that since I use RO water I need to start using cal-mag. I didnt initially run cal-mag because the micro has cal/mag/iron already. I guess its not enough? The micro is 2-0-0 and same with the cal-mag...im worried that now along with the other 2 parts (1-0-4, 1-3-4) I will be running too much N for flower. But if I cut out one of the 3part nutrients it wont be ph perfect anymore? I could use ph up or down but how does that affect the ph buffers already present in ph perfect? Many questions lol, Advice?
