Need help with leaves discoloring

Hello. Have some plants growing outdoors in New York state. All seemed to be good but then on one plant some leaves are not right ,as shown in pic. They are in 7 gallon pots. I used fox farms ocean forest and tiger bloom fertilizer( less than recommended amount) once they started flowering.
They are in flower probably 4-5 weeks left to go. Any advice would be greatly appreciated!

Check thoroughly under damaged leaves for bug pests, just to be extra cautious. By now in the season, my outdoor plants have quite a few of the older, lower fan leaves that turn yellow, but I don't see the same spotting pattern on mine that I see on yours. That spotting could also indicate something like septoria, but I don't see what looks like more advanced septoria on any of the dying leaves.

I usually pull off 5 or so fan leaves every day. I give the yellowing ones a gentle tug, and if they let go, then good. Otherwise, I check them again the next day. I don't like to leave any dying stuff on my plants.

Once I go to full bloom nutes with no veg nutes mixed in, I see a lot more yellowing in older fan leaves.

They look hungry to ME
