Any stress should only be done up to week2 of flower. And that is even pushing it for some plants.
-Its week5 man, Hurting them now will tell them to stop flowering, and spend some time healing.

Lollipop is when you cut everything accept the top 1 or 2 nodes.
-That would devastate your yield now that its just about half way done.

Dont let your branches sag on their own weight = stress = foxtailing/airybuds

Pics look great!
