I've never had a plant quite this large, there are so many same-size stems that i've actually braided a couple out of curiosity (suffocation, or stonking huge cola
we'll see).
I never actually read up on how you actually do a scrog, and just winged it, you basically grow it into the mesh, and as it grows up, you pull it back under the mesh, when you enter flowering, you should end up with a nice stem coming up thourgh each hole in the mesh, all fairly uniform in height (the whole idea of height is a uniform height for maximum use of the light)
