I'm not a stripper, so I don't defol like some do. You will get a huge range of opinions on this topic so take mine as one voice of many.
Given the humidifiers, the first thing to do is make sure no leaves are touching any other leaves. At this stage I would just take some of the inside leaves on the lower branches to make sure that you have good airflow underneath.
Once you are ready to scrog it though it's a whole 'nother ballgame, and some of the timing on that will depend on how much access you can get to them under the net. With a scrog you eventually want almost all the foliage under the net gone, as the plants fill up the net and no light gets down below anyway. And you want max airflow below the canopy.
When are you planning on dropping the net on them? Are they all topped?
