Those pistills in the photo are just pre-flowers. Some females mature early some late, she is just telling you she is ready to make some fruits! When she actually starts budding you will see pistills everywhere! Not just that one spot. followed by cola stretch every day noticeable to the eye. She will not actually bud unless she is an auto OR she only gets less then 13hrs of light per day. You may flip to 12/12 if you are ready for it and she is healthy.
