scrOG training....during veg? during flower? both? I have read the scrog bible...

I am a little confused, when do you start/stop pushing leaves under the screen? right now I am doing everythign I can to push all growth under the screen...im about 3 weeks into veg or so.......

all the pictures of scrog i see have plants sticking out of the top ALOT...do you stop training once you flip to flower? Here are some pics please comment

This is just from what I've read but you usually wanna anticipate the stretch so they grow into the Scrog and support themselves. This early on in veg night not be the best points to support, just raise it if you can and shoot for a week into flower they are getting tucked.

I'm a first time grower so if this info is wrong sorry

I fill my screen 70% ish before switching the light cycle . when vegging and during the stretch right after switching lights I let them grow through the screen then tie them down to the top side of it . Anticipate growth and don't tie them towards each other . I like to fill the outside and work in towards middle . That's way if anything gets away from me and gets tall it's on the outside and won't shadow the other plants /limbs . Also you want them tied to the top side and not pushed under because there going to need support to hold up the huge cola's suppose you do everything correct .
