Defoliate of not ??????? SOG

Hi all I'm currently running a 84 plant sea of green growing big buhhda cheese cuttings in two gt901 NFT systems I am now in week 4 flower i am aiming for true single cola plants and I have already lollipoped and things are really cramped in there now and I am just wondering to defoliate all the plants or not to allow light to penetrate better as there are lots of large fan leaves shading other plants bud sites bud I try to read up on the internet but never get a definitive answer just hoping some on here can help me out thanks pics to show

Nice setup

Thanks guys just looking for some advice

ohh sorry cobnob there is actually 88 there 44 in each system

I know the feeling. Well as far as deleaf. I have 4 plants. Anyway I have a tight space and was thinking of cutting some. I think I will bend and twist. In your case wow.

No.
