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
