Hey fellow blades, small issue going on here. On a couple of my 8 day old babies I've noticed that some are having a problem where each blade of some leaf sets are folding upwards longways down the seam of each blade. Any ideas? I think I've herd epsom salt cures the problem but im not 100% sure and am also curious what it is exactly causing this. On the infected leafs I also see a few very small spots that are lighter then the rest of the blade. Aside from the folding they are looking great! RAPID growth; about an inch each day. Big noticeable difference every time I check them when I first wake up. Doesn't seem too hot in there, humidity seems in check. Obviously haven't offered nutes yet. What could it be? Thanks for any and all help! P.S. would have pics but I've only got my iphone...
