a small problem with a few leaves, wondering if anypne can give me a clue as to what might be causing it. I'm in a 2/1 coco/perlite mix and feeding them the H3ad formula and I add calmag every 2 weeks while in veg. 6 gallon pots. It does get a little cold at night, 57 - 60 lights on 70ish. Site wouldn't let me repost pics I already posted in my journal so here is a link to the post with better pics. http://forum.grasscity.com/indoor-grow-journals/1007101-neverending-garden-10.html#post16797465
