If the leaves are drooping its cause she's thirsty ! If you stuck your finger in the soil up to your first knuckle and it was dry you should be watering it this will take away your droop and give them that nice perk we all know and love . A classic sign of over watering is the droop but it is also accompanied with some yellowing ! I would try and raise the humidity a bit as well because young seedling absorb alot through their leaves :) All in all your in good shape , just remember don't over water them when they are young less is more :) I hope you've found this info useful -Happy Growing!
