The first image of chilli crop is showing the symptoms of nutrient deficiencies. The plants are not lush green and turned to pale yellow and may be serious problem of lesser nutrients. Sometimes the roots might have also damaged with nematodes or fungal infections and also pests. So the combinations of a fungicide, and insecticide and a all nutrient mix will make chilli plants regain the lush greenness and stay healthy.

Powdery mildew disease is more prominent in regions with high nitrogen fertilization.
Cool, moist weather conditions with high relative humidity more than 97% enhance germination of powdery mildew infection. 15oC to 22oC is the best range of temperatures for development of powdery mildew.
