First of all, You don't put multiple plants in the same growing pot, because roots get intertwined, and damage each other, but since its too late now, your gonna have to hope for the best. Use some veging nutes, 10-15-10, or even 5-10-5, and make sure your lighting system is on 18/6, or better yet, 24/0. And you say you think they're female? you will never know the sex of the plant until it is put into a flowering lighting system(12/12). Also if one of those plants is male your kinda screwed, you'll probably have to cut the stem and leave rotting roots in the pot. Oncer your plants are bigger, switch the lighting system to 12/12 and watch them BUD!, make sure to research how to tell the males from females, because if one of those plants is male you need to get rid of it right away! or you will have seeds everywhere.
