Hi all! I'm growing from seed for the first time under lights this year. I have a small shoplight in a closet, and have aluminum flaps on the sides. I'm growing peppers and eggplants. Most of my plants look really good, but one eggplant (diamond variety) has been developing with a bit of yellowing and holes in one large leaf. With the peppers (jalapeno), I just have one plant that is a little under formed and the sprout leaves seem to be turning under a bit. It's also stunted compared to the other seedlings that were planted same day (I have one pic below that shows is next to another, healthier looking start)

Anyway - pictures are attached. Would love any insight you could offer. The seeds were germinated in peat pellets and then put in to miracle grow potting mix. Not totally organic, but I'm not using any chemical fertilizers or sprays. Was planning on putting some fish emulsion, heavily diluted, on all of my starts this weekend anyway but please jump in if you feel like this isn't a good idea.
