GSC fan leaf yellowing week 8 of flower

This plant is pretty healthy. This is my first grow and had some weird nute lock out stuff on my other two plants.
She is budding up nicely though still has a good deal of time to do.
I am all organic, in a FFOF/HF blend with amendments. She should have plenty of food. Possibly this is just normal yellowing towards end of cycle? I did notice that when i started seeing yellowing, it seemed to be more at some of the top fan leaves. To my untrained eye this looks like a nitrogen def. Maybe normal for the stage of the lifespan. I did give the plants a little feeding of Neptunes Harvest to try to give her a little boost.

Is this just normal yellowing?

yep nitrogen deff, you still have a ways to go yet on flowering. you csan maybe add a quick small amount of grow nutes to boost the nitrogen is thsat week 8 from begining of flip or after the 2 week streach?
nice sativa dom pheno

8 weeks from flip, though she started flowering pretty quickly.
Girl Scout cookie- looked way more indica early on. The leaves changed as she flipped to flower
