With the exception of the one with the curl, they all look great. You probably should be raising you light daily or every other day. Your node spacing looks pretty good, so if they grow an inch, raise the light an inch. How's the pH on the one with the curled leaves? It might be off in that pot or it was just over fed a bit. I would leave the one that you broke the branch off of. As long as there is no other damage it should continue to grow.
