Scrog ready for the chop or 1\2 chop opinions please

Hey all
Have part scrog(3x3) set up in a tent ,

Royal Queen seeds are in use
3 critical(54-58 days)
2 space Queen ( 54-64d)
Two of the critical have looked ready for the last week, I was thinking maybe taking the tops off the more mature plants to give more light below the canopy where it could do with some ,
Day 56 flower . pkants have gone through 14 day flush so far used gro tek solution to break up the salts for first 10days water last 4 , Got other plants in room in far side that'll be in flower for another 9 days could keep them there where possibly more down the road.
1st picture l was thinking snipping ready looking tops on this plant most if not all look good to go. worried if I do the amount stress would have her call it a day .
Below the canopy the buds our light in colour and could do with some exposure.
Thanks for the forthcoming responses turf

I've not had good results taking all the tops at once, seems like those bottom ones never do fatten up any, stalled I think from losing all the vegetation all at once, maybe take a few each a day? But really though you got a bunch either way, may be better to get the next ones in the flower space. The difference in those bottom ones now and two weeks from now will be much less than the full crop you'll have two weeks sooner.

if you're the only one trimming then DONT take it all down at once lol

Those look sweet man. I'll have to try this scroggggg technique soon... if them colas are ready. And the bottom half isn't. Chop and let those bitches ride it out another week or so...
