what is your setup. looks like light might be to close

600w MH, 6" blower through cool tube, temps no higher than 82 ever, temp of water is okayish, pH'd. Using general hydroponics floragro and micro. Any help?!

how often do you water, and how close is yourlight. i no when my room gets above 80 deg. my leaves start looking like that.

their both in DWC buckets, 5 galls. We have an LUI clone also in the same box and it looks extremely healthy, no burnt leaves at it (its in soil though). Their still young, prob a week old and they were clones with little roots, the roots are finally getting big and a significant amount is hanging out the bottom of the mesh pots now.

anyone????????

I would also say the light but check faq at the top of the site and check the plant problems

Looks like magnesium (Mg) deficiency to me, but I could be mistaken.
