These are about a month old, started off looking great and now I've got lots of curled purple leaves and some edema. Having a hard time determining the cause since it seems like too much light, underwatering, overwatering, cold, and lack of nutrients can all cause this and I know it isn't all of those. I did move my lights higher up, and watered them with some diluted fertilizer. Some of them curled more after the fertilizer. It seems to be mostly the older leaves; new growth looks better. Any other suggestions? Will they be ok? Should I start over (I have time to)?
Some varieties also seem to be doing better than others. The ones I saved from a farmers market tomato last year are doing the best, the rest were purchased from MIgardener.

Having the same problem with some of my heirloom varieties, namely pink Brandywine and Mortgage Lifter. Curled and shrivelled lower leaves, but new growth seems alright.
I’ve been cutting the lower leaves off when they get bad. I hope they’ll make it this season.
When I’m faced with a situation like this, with time to start over as you say, I always opt to start some new ones. I do that right away.
Then, after that is done, I try to find a diagnosis of what went wrong so that I don’t repeat a mistake with the new batch. FWIW, I think it’s good policy to be very careful with fertilizing small seedlings of this age. Just a bit of something water soluble, much more diluted than the bottle or package recommendations.
