So I vegged my girls under CFLs for four weeks and stuck them under a 600W HPS. Right off the bat the large fan leaves showed signs of bleaching. I raised the light to about 4 feet away and temps are mid to upper 70s but it still seems to be going on with the larger fan leaves. Should I even worry about it? The newer leaves seem fine but it's starting to effect most all the larger fan leaves. Will it cause my plants to grow smaller/slower? What should I do?
