You've still got time on all of them ....but it would appear the third pic is the closest ....if your anxious pull a small tester of that one to try.....the top two pics got a bit to go still ....lots of white hairs sticking straight out and even the orange ones haven't started receding/curling into the bud yet ......GL
Alot of breeders clam 8 to 10 weeks flower time but i find most of time its more 12 to 16 weeks.
To be honest i think they make there stats by getting there best 5 plants use the quickest to sate there flower time, the biggest for yeild, the strongest for thc % ect ect.
