I had these spots on my last crop (soil) and figured it was a ph problem. I was adding ph down and getting it below 6.0. Now i'm having the problem with hydro. PPM 600 and ph 5.9. Any ideas? I was thinking maybe I didn't mix the micro before the bloom and locking some nutes out. So I flushed for 5 hours and re-mixed the nutes. I was using B.C. nutes before, now I switched back to GH. I'm hoping when I go in there tomorrow i'll see a change. Any other ideas?
