Magenta pink spots on yellowing rose bush leaves

I have "magenta pink" spots on yellowing rose bush leaves.  They aren't like regular rust spots as they are really very pink and on the top surface rather than bottom surface o the leaves.  Any ideas?

    It's best to supply a photo as I cannot see what you are seeing, but I get all sorts of blemishes on roses this time of year as they're winding down for autumn, which allows foliage to succumb to all sorts of things... so they eventually defoliate for winter..

    I doubt it's anything to worry about... I've had a couple of frosts already, perhaps you have too ?   this brings things on a bit..

  • The colour in the photo isn't as vivid pink as the actual spots but does give you idea.

    Botrytis blight on roses, I would say, although I'm not a plant pathologist... just pull off any affected leaves and discard them with the rubbish... nothing to worry about...  it happens when the weather cools...

    ...oh and thanks for supplying a photo, very helpful to see...
