Usually you want to fill maybe .7 x .7 of the space (~50% area=LxW). If you have controlled any side growth with the scrog, it should just grow vertically eh? So, just a matter of filling in, maybe some selective pruning to even her out, and away she goes whenever you want... and space allowable. It's got another ~3 weeks of vegetative growth after you switch to 12-12 schedule. Even spread out it'll put on some good height all over.
Might want to leave the outer most net open in future? you'll know better than me in a month or two. Great thing about the diary is you can go back and see all the pictures and notes and do it better next time. So many personal preferences are invovled. Take anythign i suggest only as a generalization that may need to be translated to context or only loosely used conceptually.
