The leaves do kinda look fat. I think thats due to heat or maybe just plain genetics. Either way it's nothing to worry about. Instead of pruning the leaves try tucking them in or tieing them somewhere. That way you induce less stress than if you were to prune them. Otherwise you seem to know exactly what you're doing and it looks as if it'll pay off in a few weeks. Very nice plants. You should be proud. Goodluck and welcome to the forums.
