Lavatera disease

I have a Lavatera newly planted this year.Until recently flowering well and looking healthy. Now I have seen pustules on the underside of each leaf and the plant itself is not as vibrant.I am sending photos.
I would be grateful for advice as I was very happy with the plant until recently

This looks like “hollyhock rust” which also attacks other members of the mallow family, like Lavatera. Here is a good article on the disease and steps you can take: https://ipm.illinois.edu/diseases/rpds/627.pdf ^[1]
