When is the best time to top your plant. (cut the top branch so it splits in 2)
I would not reccommend that. The plant would spend the first 2 weeks in flowering phase stressed out and this when you should be having explosive growth. It is always a better plan to allow the plant to complete the recovery of being topped or fimmed before flowering. That process usually takes 2 weeks.I do it the day before I put them into flower help to stop steching
in the final phase of the plants life.
