What to do? My nasturtiums have some curling leaves that are dying. Leaves get yellowish spots. Does not seem to b the whole plant.

Yellowing leaves can just be the natural aging of the plant.
It also could be watering, either to much or too little. Either extreme can cause the deterioration of the plant.
Inspect the plant for signs of aphids or other insects. A treatment of Neem Oil can be used if you find evidence of infestation.
