I have an indica dominant about 7 weeks in DWC bucket, 4x4 tent, 600 wat MH. Temp 77 humidity 40 - 60% maintained with in room AC, 4" carbon filter fan pulling through light hood. Using ph perfect micro, grow, bloom, and B52. Topped, supercropped, micro cropped, now dim and LST bending. Plant has looked incredible imho. For the last week I've noticed brown tips and tiny white spots that go through the leaves. Was the biggest leaves first, I cut them all off, now it's to the newer leaves. I've looked with scope, no bugs.
