I think you've done a commendable job RastaBud. Your plants are definitely Indica dominant as evidenced by their fat chunky leaves. You may wanna transplant your girls into the next larger size pot before you put 'em into flower because they're still gonna get another 20-30% larger as they fill out and ripen and that means the roots will continue to grow a bit more as well. Once you switch the light cycle to 12/12 you'll know in a week to 10 days if they're boys or girls, the boys always show sex first so if you don't see lil' balls forming around the nodes by the 7th. day, they're probably both girls. Good luck to ya and keep studying up, you're doin' well. :thumbsup:
