You kind of ansewered your own question,Drooping is mostly caused by either under or over watering,

At about 80f they should perk back up in about 3 days from overwatering,or a few hours after watering if they were underwatered.
kully Reviewed by kully on . trouble after transplanting... Hey, so I just transplanted one of my seedlings that is about 10 days old into a larger container today. This was my first time transplanting anything, and I thought I did everything correctly. But, tonight I have noticed some drooping of all the leaves. The only thing I can think of as to what is going on is maybe I over watered a bit. I don't have any pictures right now. It's not drooping a ton, but it's definitely noticeable. If it is infact just some over watering, how long do Rating: 5
