if roses get this you have to spray every two weeks , constantly prune, even during flowering. so if its the same for bud then it might be better to start over did this plant get wet from rain maybe ?

It's Septoria cannabina blight. You can slow progress by spraying with Bordeaux Mixture, but once the plants are infected that's all you can do.
