"Schwazzing" is a time sequence for defoliating cannabis plants in the flowering stage. By defoliating at Week 1 and Week 3 of flower, you can dramatically increase your yields!
I'd strip all those leaves back completely the entire plant top to bottom then you'll be able to have a good look at the structure and make any pruning decisions you need to. You might be in a bit of shock seeing her after, but in three days you'll hardly tell you did any defoliating.
