If you're planning on harvesting within a couple of weeks, there's nothing you can do.

Next grow, keep in mind that cannabis loves phosphorus (P) during most of flowering and potassium (K) from the middle to the end of flowering. What I'm seeing here looks mostly like a P deficiency.

So I should just wait 2 weeks and harvest? I heard somewhere about reducing light time to force the end of flowering. can It work?

Feed 1/2 strength bloom feed. Easy on any nitrogen. Then observe.

I harvest based on trichomes.

I have reduced lighting periods to 11 and 10 hours and the plants did not ripen faster than they did in previous grows of cuts from the same moms. I do not recommend it. In fact, I now do the opposite. When the plants are about a week to 10 days from harvest, I flip back to 18/6. It seems to beef up the buds.

To be sure, flipping back to 18/6 is bro-science, at this point. I never proved it increases yield. It's one of the many side-by-side tests I'll perform when I'm only working one job.
