ok...i've done this before i know what they are supposed to look like and that htey are just babies its just i never seen the leaves not fan out a bit more. These are a little curled up and a lille twisted thats all. But they seem to be growing healthy. I just took them out of the humidity dome too. They are just getting 100% sunlight.
That can happen if you are watering them too much. Sometimes under extreme overwatering conditions, even the stem will curl up.
Cut back on the H2O for a little bit.
Good luck!
