How often do you mist with rain water? I think we may have found your problem on both counts. Did you know that water, rainwater ESPECIALLY, can leach nutrients out of the leaves? That would explain the pale new growth, and water beading up and burning under the light would explain the rest.

Help, It's getting worse I moved these 2 plants from a grow cabinet I had in a garage to the flower room in the basement. and I noticed a couple days ago a few spots on a couple leaves. I thought it was bugs so I have been spraying with neem oil.This morning it spread to more leaves and now it is taking over the plant. It is 83 degrees and 55% humidity. In soil, using GH 3part +calmag,liquid karma,hygrozyme. watering with this every 2 days. Rating: 5
