Hey guys I was just wondering what the leaf curl on my tomatoes mean. I know they try to curl up when its to cold for them, but they still curl up a bit even on sunny days. The leaves are not dry from being under watered. I have them in a DIY earth box set up. My guess is the roots are drowning in the reservoir? Or did I mix to much "hot" soil into the normal top soil?

this is when i got them from a local nursery may 12th


This is them on June 1st
