The leaves in the bottom right of the pic I know are definitely okay. It's the ones in the upper left I'm worried about. I'm sure I'm just being paranoid. I really want these to grow out and thrive.
All 3 of the seedlings (the other 2 are sun gold cherry and golden san marzano) are in separate 20-gallon pots, outside next to a very sunny wall.
Thanks again for your help!
