Scrog advise needed

Im 4 weeks into flowering in a scrog set up. At what point do you stop training the plants. I have stoped but was wondering if i should keep pulling the stems under my screen or just let it grow.

you stop when you've got all your cola points nice and evenly seperated out through the screen and you feel confident that they wont just shoot off into the light and bush out further choking off the parts of your canopy...the screen is basically a canopy holder to keep it all at the same level. So if you've got bud sites and heads of pistils coming in i'd say that's a good time to stop weaving. If you give us a picture of what you've got going on so far we can better answer your question
