Hi all. Can you see from my four/five week old seedlings any problems with them? In the 2nd pic there are a few new leaves that are brown and withered. Is it crying out for nutes? So far I have been feeding them only water when the top two inches are dry with tap water that has been left for one to two days. I put them outside about three days ago. Should I bring them in of a night? All help/advice will be greatly received...
