If it is in your window, does she receive artificial light during the night time from you being in the room?

if so that plant still thinks it is summer. In the southern hemisphere your daylight periods are now to short to flower properly so you need to transplant her to a 20 liter bucket. buy a timer, get a bunch of CFL's or even better a HPS and put her in a closet and set the timer to 12/12, then in about 2 months you should have some nice buds.
