Powdery mildew on Bush Blue Lake Beans -Organic gardening

I’ve noticed some Powdery mildew on my Blue Lake Bush Beans. (Planted from seed, Burpee Variety) I sprayed them with neem oil (Bonide), they have lots of flowers, and looked healthy until yesterday. I try to not overhead water (hoselink, semi hard water) but it is hard as I have them planted close so they don’t flop over as bad. Any tips? Should the neem stop the mildew? Thanks. In Oklahoma City Metro zone 7A/B (my garden varies from 6A-8B depending on area and proximity to house).

Some has spread to a nearby cherry tomato, I sprayed it as well. Hopefully it will be okay. It’s nearly 8ft tall at the moment and loaded. Super Sweet 100 I believe. Bonnie plant from Lowe’s.
