First time growing... So far shes been growing steady, but I'm worried some leaves seems to be curling/darkening. Three days ago: Yesterday: Today: I have two worries: One is that the bottom of the stem is weak... I think it didn't get rooted in the AG pod correctly and is now not dry enough to get stable (thats why I have the straw setup..) The other is the leaves... nutrient burn? I've been monitoring PH and keeping it between 5.5-6 and adding nutrients slowly after flushing the res a week ago. Also added a bit of Epsom salt and have been circulating air daily with my window open.. Any advice/critique appreciated... I'm just waiting on the rest of the seeds to get here
