Yellow leaves in flower

Roughly 7 weeks in. From research I understand some yellowing is normal, I’m just wondering if a more experienced eye can tell me if this looks normal for this stage or if it’s something I should be concerned with. My concern is the fan leaves yellowing, mostly midway up the plant and looks to be progressing to the tops.

I'd give it a good feeding. I'm thinking it's wanting P, so I'd make sure to use some flower nutes.

What are you feeding them, and what's your medium?

Dynagro grow protekt and bloom. Happy frog soil. Switched to a 1/1 mix of grow and bloom for the first few weeks of flower and slowly lowered the grow amounts. I’ve been giving 3ml bloom 1.5 ml protekt per gallon the past few feedings. They’re fed 2 times a week. Just fed them today actually.
