If you see my roses, they have NO botrytis.Or powdery mildew or downy
mildew. Some of them are getting spotted from rain. Seen it happen for 7
years to them. Some just rot on the stem, Brides Maid especially. Not
enough heat to make all my roses pop.
Seems like some of my roses have a very high petal count, Very dense buds,
They just don't open until the 2nd or 3rd bloom cycle.

Sorry I don't understand.
Water by itself does not
cause any damage.

It promotes growth of Fungii.
The fungii cause discoloration.

Check out Cass's link.

I have seen rain cause colored spots on my roses. No fungus here.
Just bugs.

You have botyritis.
Time to spray.

Same thing happened to one of my iceburg roses. Its next to several
red
roses including a Mr Lincoln and now it has red spots all over the
flowers.

I think that its partly due to the weak nature of the particular
plant.
Another iceburg in the same bed, which is stronger, is not affected.
