Mixed up my skywalker and LA confidential

I mixed up my seedlings cuz i forgot to label them cuz i was in a rush when i planted them. Will i have to wait til i flower them now to see which is which? Skywalker og kush by reserva privada is mostly indica. LA confidential is 100% indica can i tell by the leaves or wait to see the flowers?

How did the harvest turn out? I am interested in trying both of those strains.
