Normal yellowing?

First time grower. Overwhelmed with reading on here. I'm a few weeks into flowering. One plant is Urban Poison the other is Wonder Woman. My question is, does this yellowing of the leaves look normal toward the end or am I doing something wrong? Thanks for any help.

Pic one the looks ok. the fan leaves are yellowing the flower cluster leaves look nice still.
the other pictures look like they could use just a touch of (N) they look a little to yellow looking at the whole plant.
Or you could just let them do there thing, I'm confident they'll finish ok for you.

Don't stress the Durban Poision it's an unstable strain.

Look fine, but what topfuel said.

ur ok, its a part of life
