Perhaps I missed it, but how old are the plants? To me, they dont look anywhere near done. Since the sugar leaves are still green, I'd let them go. Without the fan leaves they won't do much as far as yield but you can at least get a little bit more mass and let the trichs mature to get the most out of your work.
The above post is fictional and should in no way be taken as truth.
If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.
