Coming along beautifully there! Very nice scrogginess
If you are going to use the screen for more than holding the branches apart - i.e., if you plan on training the branches horizontally under the screen (dare I say , "as in a proper scrog"? please don't rip off my head, guys! lol ) - I would secure the string on your screen a bit more (eg. loop it around the screws once) - otherwise it could get pushed off by your princess. They do strain upwards despite their training and I am seeing the screen being pushed upwards pretty decisively on my own - and many other screens
Also, if that is your final screen height, I think you may have flipped too early.
Check out this C99 scrog and when it got flipped to flower -

apparently, the C99 doesn't stretch much!
