AsNoriuanswered grow question 3 years ago I usually do defoliation in veg just to them get used to ;)))
But I veg longer in such cases and LST a lot.
Would leave them alone till day 14-20 of flower, depending of how quickly flowers will appear , and them lolipop them, defoliate, tie, support.
If you still will do it now, give them not less that 4-5 days to recover.
You can give extended night on transition/switch day.
But don't give more than 8-10 between defoliation and flip.
That's my personal notes.
All the Best !
