i'm growing indoor and until recently used a bunch of CFLs. two weeks ago i made the switch to a 400watt HPS. there's only two plants now, 1 female that's about 5 weeks into 12/12 and one that's only a week past seedling. Around last week i noticed that the inside of the leaves emanating from the growth tip on top have these bright yellow areas. I moved the light a little farther up, figuring it was being burned by the light. I heard if it's too close it can bleach the leaves . .? can anyoen offer some insight? I also noticed the leaves on the new plant are taking on a more yellowish hue. there are more pics in my grow journal. all help is welcome! thanks y'all
