Took a couple last shots of the Hooch before choop, I may put this and the other 2 flowering under 20 hours light for couple days.
Not sure the results but I don't think much worse can happen.
Have you ever switched you flowering plants to longer light at the end of cycle?
I have been reading some people move it up slowly after week 6 to end the final week under 24hours.
As with most cannabis growing it is all about experiment.
