I would advise turning the lights off for 48-72 hours prior to starting the flower cycle. This will shock the plants and jump start the budding process. Also, when you are ready to harvest, I would do the same....it helps push out any last bits of resin.

Also, you can put plants back into vegetation after flowering cycle has started. I believe it's called secondary budding. I've heard that it can increase your yields by about 25%. Which could be worth it if you aren't worried about time.

Good luck! :jointsmile:
