There are several foliage problems that can affect nasturtiums. It is a good idea to remove any infected leaves as soon as they appear to try to control the problem, avoid overhead watering especially at night, and make sure they are planted in a location with good air circulation. You might find that a neem oil based spray applied according to the label instructions is helpful in controlling the disease.
