Looking real nice Shov. How tall are they?

They look ready to flower but I see you still have some horizontal space. I wait untill 3/4 of horizontal space is full, I keep my plants LSTed to no higher than 8'' untill I can't see the bucket looking strait down. Then let them veg vertically until they are 12'' to 16'' tall. this all takes around 6 to 8 weeks.

Just something you may want to try. oh yeh forgot one thing. something else I do is trim the fan leaves that cover any new branch top from direct light. This is 90% of the time the ones that point strait up when you LST and I remove them at that time. Branches seem to grow quicker when I do that.
