I have 15 plastic solo cups with three seedlings per cup of heirloom tomatoes. I have been so incredibly cautious about them! Reading everything on these forums that I could, planting them correctly, etc...I woke up this morning and the leaves of about half of them are pointing toward the ground. They're in a rainbow shape instead of being horizontal to the ground.

As some general info, I have them about two inches from the florescent shop lights, and I watered them for the first time yesterday by bottom watering them with a tea mix to prevent damping off. They're almost a week old. The only thing I can think of is that my soil might be cool. Any advice would be great!!
