Rosebush problem

Rosebush problem

Hello, I just planted the most beautiful rose bushes a few weeks ago, but for whatever reason they don't appear to be doing well anymore like when I first got them. On their leaves appears to be something that looks like they were watered with milk leaving a weird milk stain. It's not fuzzy or anything, just like a dried milk stain. Any ideas?? Thanks!
