I'm new to this myself, but am still fairly confident that you cannot change a male plant into a female plant. We'd all be doing it, otherwise. Any pics? There are some instructions in the FAQ on how to determine the plants sex, which may or may not be of any help. Good luck with those plants!

I am almost positive that @ 3ft tall they have been showing pre-flowers.
