The white spots could be powdery mildew, unless the white spots also have the holes in them. Then it is likely an insect problem or perhaps even a caterpillar problem. For powdery mildew, check out this article: https://www.gardeningknowhow.com/ornamental/flowers/roses/roses-powdery-mildew.htm .

Also, there is a great site to check out of finding out what insect or caterpillar might be making those holes in the leaves here: http://www.sactorose.org/rosebug/

To control the insect or caterpillar problems, a product called Sevin or one by Safer, called BioNeem is good.
