Plenty of people do it, but there is an increased chance of hermies or males, since the plant is put into a stressed state.
I got neg repped the last time I said this, but I don't care. It is the truth. Some people just get defensive when you point out problems with methods that they use.
My advice, if you have the extra room and time, is to grow the plants to maturity, pick a good healthy female, and turn her into a mother plant to take clones from. All the clones will be guaranteed females, and you can safely flower them straight away. Plus, you never need to buy/acquire seeds ever again.
