Doing a scrog..
Yes, 100% do it now.
All will be blocked out so, u need to build the top as much as possible.
Leaving bottom shoots on will sap energy from there..
Really should of been done during the stretch before preflower. But, its far from too late. No large stigmata on top (hairs) so she's still good to go imo.
Really those nodes should be weaved thru and under the net, and only 1/4 or so of the top above the net. (Before pre flower).
