Need some help with scrog + lst

I am currently in the bloom phase after 5-6 weeks of vegging and im wondering for how long i should keep tucking the tops under the screen.

There is about a foot left of space above the screen for growth, should i keep tucking for long as i can or would this stun the budding around the area where the stem touches the screen?

Let them grow up through the screen. The screen is meant to hold up the buds.
