Man, you are using big bud coco wrong. It's only meant for the first 2 weeks of bloom. And it's clear your PH/lack of nutes is way off. I wouldn't put it down to C02, more of a lack of tools buddy. When growing in coco you gotta feed daily with every nute. So say I give 6 nutes to my plant, and I'm using coco, then you have to give them nutes everyday. And never use bud bloomers on veg, your asking for trouble, and 1 more thing. The way you have your pots In water, that's wrong, that will cause root rot and stunt your growth. If anything leave them in that tray, and put your pots on something and the roots will make their own way into the water. Hope this helps.

@Growladyeastmidlands, thank you. Does that mean there won't be any THC in the buds? Shall I even bother to dry & cure? They smell very 'weedy'

@Scooby_Doo, I think they pollinated check in buds for seeds
