I wouldn’t take off anymore leaves at all.. but if you are wanting to concentrate bud production up higher I would probably take some of the actual buds off of that bigger pheno you have. Just on the older lower growth, like maybe two nodes/bud sites on each branch so you still have plenty above it.
That lower stuff won’t be as dense like you’re saying.. it’s up to you if you don’t mind some of the popcorn bud leave it be but if you prefer focusing on the big tops, definitely take a few lower bud sites on each branch.
I usually leave like 4-6 nodes up on the top of each branch depending on the strain and how close or far the internode distance is.
Good luck!
