That bud is 2 weeks from being fully ripe. A re veg takes about 30days, then you got to let it grow a month or more and go though the whole bloom cycle again. Keep her on 12/12 enjoy your self a nice joint in a few weeks and start over and try again. After your next seed sprouts give it about 3 weeks then transplant it into a 10-15gallon pot keep it on 18/6 for another month then switch to 12/12 to bloomSo yes I Beloit may be lack of light I will work on making sure the plant receives steady 18/6 lighting
