Ok you have been starting very well on your Girls training looks good. You just have to go on with them. And yes choosing the right genetics is a big point in scrogging. I failed with my choice . I had misty gorilla and it was quite impossible to mainline them. The branches were so sturdy and the leaves so robust. I gave up on them. ! plant was aC-99... and she was great to this job.
I ended in giving up and let them grow like they wanted to^^.( diary: See-99 Gorillas in the Mist)
In your case its a good start, you may perform it a little longer and go on training, and defoilating them.
And in my opinion your scrognet is suboptimal. To big holes in it... look for scrog that has 6-cm holes,
but alltoghether girls look fine just keepon training
