Yellowing of leaves towards the end of flowering is normal Darwin. Those leaves are passed their use by date. Just rip them off and the buds will keep developing.
thats what i would do
thanks a lot for that guys, just wanted to double check as i've seen a few cases of nit def etc in flowering that looked similar. thanks again i guess they are nit def technically as the plants pulled all of the nutes and resources out of those leaves to feed the buds! could that mean that i need to bump nutes up slightly?
