Check the underside of the leaves. Looks like it could be spider mites or thrips. Happy growing

Thank you what should i do to treat?

Can it be wiped off the leaves easily? If yes then it’s white powdery mildew. It will spread to the whole plant and nearby plants if left untreated. Caused by high humidity and warm temps facilitating the growth of fungi. Can treat with 1tbsp baking soda and 1/2tsp liquid soap mixed into a gallon of water then put in a spray bottle. Neem oil works too but if it gets on the flowers youll taste it after harvest
