Hello! The amount of defoliation you do is dependent on your environment. There are some details missing from your diary. But how well are you able to control humidity? And what kind of airflow do you have?
If you able to control humidity well and you have good airflow, then minimal defoliation would be my strategy. Yes, some of the buds will end up being popcorn (but you can clip these into a freezer bag and then store for a press in the future).
If you are not able to control humidity well and/or maybe not able to get good airflow, then I would basically strip the bottom third of the plants as well as remove leaves that are touching or overlapping each other to better expose some bud sites.
Ultimately, it's your call...and your environment...so you're best to judge. You want to negate risk of mildew and mold but also minimize stress to the plant and preserve its solar panels (leaves)
