Seedling leaves just look funky sometimes.. dont worry too much about it.. she looks fine
Just dont over water, as that would be the only thing causing leaves to be droopy for you right now, outside of just odd leaves.... water THOROUGHLY, and then you dont have to water again until your medium is dry a good 2in down.
For me personally, I'll stick my finger as deep in the soil as I can to test for moisture. If you water every time the top layer dries out, without allowing the entirety of the medium to dry out, your root system will be shallow and weak, and you run the risk of rot.
Allowing your soil to dry between waterings allows oxygen into the root system, and forces roots to spread in search of more water
