I dont know wheter it works or not but give this a try u might get a hermaphrodite.
Yeah chop them balls off lol
I been told that in the middle of letting ur plant sleep to give it an hour of light then back to sleep in total darkness. Keep repeating the process and i've been told the plant can change sex or turn into a hermaphrodite. Give it ago cant do any harm as the plant is pretty much useless unless u make hash or want the pollen for seeds.
