Cotton Seedling Problems

I seem to be having an issue with the cotton seedlings. Not quite sure what the problem is but they do not seem to be responding well to the environment. Actually, I am expecting to lose at least two of the three in the next week or two. Quite possibly it's a heating issue as I am trying to grow them in a basement in the northeast during winter. The plan currently is to plant a couple in the flood table and a couple more in the current planter and monitor these a bit closer.
