UGH! OK... Today (monday) is the third day since they've been in the systems and the 18hr light cycle has started! Two of the girls look GREAT! But two of the others aren't looking so hot! They seem to have gotten a little yellower and one of them is even starting to brown ever so slightly along the edges of a few leaves. I just added more nutes to the mix and got a spray bottle to mist the leaves and such. If anybody has any other suggestions please let me know! Thanks guys!
