Thanks Lin and Tarev! I bought it 10 days ago in a plant shop. When I saw your answers, I remember than the friday nigh I forgot my kerrii out. It stayed all nigh without roof. We are in autumn but it is not cold yet, at night about 10 celsius degrees. Black spots may have appeared from the cold, but it has white spots (I have removed them with a napkin) as if it were powdery mildew and on the stems of the leaves it have small black dots. Today I will buy systemic fungicide, have you used any?
