Did she start flowering?

There does seem to be some pre-flower/pistils showing. Pre-flowers is not flowering...........flowering will start about 2 weeks after the first pre-flowers appear. Do not switch to "bloom" nutrients yet, continue with "grow" nutrients until there are small "budlets" starting to form,. This will keep your plant healthy and prevent it from running out of nitrogen half way through flowering. By the way.........never grow at 24/0, all cannabis plants NEED "sleep" for a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will never grow to its fullest potential. 18/6 is optimal............anything more is a waste of electricity.

i cant see it very well. but it does look as if she may have some pistils there but i dont actually see it. it does look similiar to what i know bud sites look like from that
