I'm a fan of defoliation myself... Having experienced bud rot destroying a grow, I want as much air flow through my plants as possible ... and having had grow after grow produce decent sized buds on top but small buds underneath with no stacking except for the main cola, I want to get as much light into my plants as possible. You can see what I've done in my #2 Bruce Banner diary and how all of the side buds are stacking up beautifully... watch the video here...
growdiaries.com/diaries/154058-grow-journal-by-growinggrannie - I made the mistake with my #1 Bruce Banner of NOT defoliating because she was such a gorgeous looking plant.. full, thick, and EVERYTHING was frosty.. when I finally realized I was not going to get the bud development and was most definitely risking bud rot, I had to do some but by that time, there were precious few leaves that did not have a thick coating of sticky trichs on them and defoliating her even a little was worse than any wet trim session I'd ever had!
But it's not for everyone and not for every grow. My Pinky is probably never going to need defoliation (
growdiaries.com/diaries/157106-grow-journal-by-growinggrannie - and again, watch the video) - and if she does need it, it will probably be only a very little. A good article to refer to is this one - it will give you the when, the why and the how ... https://www.growweedeasy.com/nebulas-super-simple-3-step-defoliation-tutorial
All that being said, if this was my grow, I would definitely be defoliating some more... the interior of the plant is very dark and I would worry about both bud development and air flow... But that's NOT to say you won't have a good harvest if you leave her be...
Good luck!
