temps gotta be low 80's or 80. no high humidity though. area is a 12ft square space, closet. no door, but a tarp with mylar covering's the doorway in a small air conditioned bes room, tarp always partially left open about 20 inches or so. area also has 2 fans blowing in it 24/7

ohh btw im using 2 lights a 400 and a 250 metal halide, was giving plants light 24/0, switched to 18/6 today with a new digital timer, shortly after they went off the first time, i did a foliar feeding. plants are at day 41 from sprouting. also im using growbig, some sea kelp, and superthrive.

I ask because I have the same problem. Now, I too hava a 600 Watt MH vegging, mine are 32 days from seed and its only affecting the bottom first set of fan leaves. Its normal, lights dont penetrate all the way through, I just cut em off yesterday.

I grow hydro though, but yeah, mine looked exacly luke urs. I wouldnt worry about it.

the pic in my avatar was a seedling at 45days old. I cut off the bottom leaves that was turning like urs. its just natural, they dispose em after they have no more use of em... normally the bottom fan leaves serves as an energy base for the baby shoot. as so does all fan leaves, but the bottom one is the oldest.
