• She's just recovering from overwatering and nute def. ... She's been growing but now i see a purpleish outline on the leaves. I have a 2 week old seedling as well with the same purpling around the leaves. Can it be light burn? They're under a 600 watt mh View attachment 2145475View attachment 2145476View attachment 2145477View attachment 2145478View attachment 2145479View attachment 2145482View attachment 2145483View attachment 2145484View attachment 2145485View attachment 2145486View attachment 2145487View attachment 2145488View attachment 2145489View attachment 2145490
