Yellowing day 37 flower

Hi all, I posted in the organics section but had no reply. Basically growing a merry berry in allmix using living soil dry amendments , she is currently on bloom 1 and will be introducing bloom 2 in 2 weeks, temps are 27°c lights on 52% rh, lights out 22°c 60%rh. I know the rh is slightly high but I have alot of air movement. I noticed 3 days ago that some of her leaves are starting to yellow. If you have any advice or knowledge please try to help if you can

Hey GTG1986. She looking good. I have a plant currently in day 49 of flower and some of the older, lower fans are doing the same. Your baby looking healthy, I'm no expert, but I'd say just watch her. Doesn't look like much to worry about.
