You can try putting it on 12/12 I did on some but they where budding really slow so I cut them down
Did that with a supper kush but think that was too much feed
I had one JH on this last grow that would not flower no matter what. Just chopped her. The grow before I played with light cycles and hermied.
Whenever I have an autoflower that won't flower, I just assume it's actually a photoperiod and put onto 12/12 light cycle for the rest of the grow.
@Lucas598 I haven't done a video on it. Not sure what else I could say in the video except change to 12/12 light cycle?
