I bought this plant 1 months back and kept in my East side window which gets at least 2 hr direct morning light. After few weeks I spotted this small dots on leaves and the leaves were turning brown. My place is the n East part of India 121 km away from Bay of Bengal sea. It's a rainy season here with a high humidity level and temperature roams around 27-35 degree Celsius. Please help. Don't want to lose this plant.
