It is planted in a container that had begonias in last summer and I used about 3/4 of the old growing medium. Has full sun. Lots of water. I used some 6-8-6 fertilizer. Does it need more nitrogen?

It appears to be "anthracnose", a common fungal disorder.
There is no curative treatment for an active infection and affected leaves cannot be restored to healh. But for prevention of new infections, besides sanitation mentioned in the second article, you can spray 70% neem oil repeatedly through the growing season. Or a biological fungicide.
