not quite sure what's going on with them now.. I haven't changed lights or anything.. The true leaves are starting to fold back up(towards the stem) on some of them.. They were all spread wide before, and are now folding back.. The stem is finally starting to pull about 3/8 of an inch away from the first leaves(cotyledons). Am i not providing them with enough light, or what? I dont want them to die

When i say 'fold up' i do mean UP, not down as if they were being overwatered..
