Some Leaves On Brunfelsia White Caps Turning Black

Question

Not all the plant is affected and the leaves otherwise look healthy. There are no obvious insects. The black shows in the veins of the leaves – maybe a nutritional problem?

Issues could range from nutritional issues, ph issues, temperature and humidity problems, too much or too little sun, and problems with soil composition. Testing will be required for pH and soil nutrition, first and foremost. Here are some articles that will help:
