Hi,, this is my second grow using H.G in coco and seem to be having the same problem with firstly cupping of the leafs or 'taco leaf' and the stems seem to go a purple color, as they get a lil bigger it seems to rectify itself but am still concerned they're stunting,,, every deficiency I read up on seem almost identical with they're symptoms..its hard to know what's what... Id appreciate any input
