Quick Question, please help!

Ok,
so im in the middle of flowering week 5 and these leaves on my plant have been yellow and difficient looking for a week now. (caused from slightly to small of RW block)
nug is a little slower developing than the rest of the plants but they are near the top as you can see.. think I should ex-em or let em go?

I think the yellowing is normal as the last few weeks it uses the nitrogen from the leafs and uses it for buds..

just let them keep going its not that big of a deal.
