I would not worry. For me it looks like some kind genetic mishap and when growing along it normalizes. But just make sure and for peace of mind let dry good and after that water only with like a coffee cup once in three days and go from there. Also you can put some fan blowing towards those pots if you are afraid of molds. They look good to me.... maybe root zone is getting little small and that can cause those wrinkle problems hehe . Happy growing hope this helps.. P.S add inch of clay pebbles bottom of your pot before putting any soil in. it helps to get good run off and helps to avoid those moisture related problems.
