What is happening to them?

I thought it was brown rust so I started using neem oil today.

Can you post a photo of the whole plant?

This is not rust. Rust is characterized by orange, circular pustules, and they typically shoe up first on the underside of the leaves. Looks like it may have a blight. If it is, you will need to apply a fungicide.

Will neem oil work?

No. You need a fungicide. Try copper. Neem oil has limited uses, and in the summer, can actually burn the leaves.
