The tops of my plants started turning white. I thaught it was just the strain (Nothern Lights)???? Like the buds had no pigment but a ton of tricomes. Is that from too much light? My last grow I had 4 lights over 12 plants in and areoflo2 system. I upped to 22 plants on this grow amd I'm using 9 UFO style LEDs in a 6X8 room. Too much?
