Is this amount of yellowing normal

Two of my girls are about 5 weeks into flower outside and in soil. Had no probs nutes wise leading up to flower both had a very healthy green and grew wonderfully, however many of the leaves have now turned yellow. I know that it is a normal process for some of the leaves to turn yellow however I am concerned that this appears to be a bit too much. Can anyone confirm this is to be expected or am I witnessing a fuck up on the home stretch? I've included a pic of a bud from one of the plants to see its health and development.

There some nice big girls you got there mate
Im not to sure about the yellowing as im only
part way into my first indoor grow!
As your growing outside id say it looks seasonal as
we are now coming into winter.
The plants look to be changing with the season.

Im no expert though and know nothing about growing outdoors!

Sorry mate I cant be much help.

Good Luck and I hope its nothig to serious.

Post some close up pictures of the yellowing leafs.
Im sure someone on here can identify the problem

It is normal the buds are using up all the good stuff out of the leaves to flower.Nice plant

Thanks man *sigh* of relief

Agreed. That's normal given the stage your girl is at. Mine did the exact same thing. Nice plant, and good luck with the harvest.

giving a third opinion.... same as the other two, this is normal. lookin good
