Cutting The Top

Which Is The Best Time To Cut The Top My Plant At? pls

as long as you don't do it too early any time is alright. You want atleast 6 leaf sets with new grow tips showing at the internodes. That way new tips will grow up from the nodes below. I like to have 4 grow tips just underneath the top bit of the plant I will cut. This top bit needs to have the main tip with 2 new nodes forming just below it. Once the plant looks ready I give it 2-3 more days to grow a bit more, then I chop the tip, leaving 2 new shoots right below my cut with 4 more further down which should then develop into 6 main tops.

Thanks my friend , i was going to cut the top in the second week of flowering
