I only grow DWC/ Hydro, with the help of these great guys it was figured out of lights being too close and running the agressive veg nut mix. Foil was for a extra layer of light blocking. In hydro no light can enter the res where the water sits or it grows bacteria and alge. per the setup its a 5x5 tent indoors, 1000 watt led and dwc. after raising the light a few inchs and flushing out the tubs and resetting with a medium nut mix they went back to their normal selves
