I wouldn't worry about that much curl. I have many that are worse than that. Why do you have plants under the lights at this time of year. Don't you have a sunny place outside?

Why is this happening to the plant though? too much water or did it go to transplant shock?

I'm just experimenting trying to see what vegetables I can grow inside from seed to maturity :) and at the same time learning about gardening. Unfortunately I don't have place outside that I could do this so this is the next best thing.
