There looking pretty good so far, but like Dutch said, get them in soil asap. Once you get them in soil try not to drown them to much when their seedling. If you want to try a good natural fert try fish emulsion. It smells like s**t, but it works great without the salt buildups you get with chemical ferts. Make sure you have good fan on them. Not only does the fan circulate the air it also helps the stems and branches get stronger.
Good luck with you`re grow Chili
