Q.disease on my chili pepper leaves
I have chili pepper plants growing and on all the leaves there seems to be a disease that looks like bird droppings and is spreading. I have researched this and cannot find anything that appears to be the type I have. Also, I grew some from seeds that I started inside the house and they were fine till I planted them outside. I also had a flood a few years back and the plants died, and this year the seeds came up by themselves and now all the plants have the same issue. What is it and what can I do to clear this up?

It does sound as if it is a fungus issue.
Crop rotation is a good idea to prevent this from spreading.
