I noticed these rust colored spots on one of my plants while it was in veg. i figured it was mold or something so I culled that one out. Now all her sisters are in flowering and im noticing the same rust colored spots on some of thier fan leaves. some of the really bad ones are starting to dry out and krinkle up.
Im thinking its either a magnesium/calcuim deficiency, or some kind of mold. probably the latter because it seems to spread through physical contact.

anyway, heres what im running

400 watt hps, vented, in a 3x3x7 grow tent
78 degrees F, 50% RH
ocean forest soil w/ 35% perlite
botanicare pro grow/bloom, cal-mag, sweet.
foxfarm big bloom

anyway, heres a couple pics. hope you can help!:hippy:
