How can I identify and treat plant yellow spots on leaves?

To identify and treat plant yellow spots on leaves, first, examine the plant for any signs of pests or diseases. If no pests are present, the yellow spots may be caused by nutrient deficiencies or overwatering. To treat, adjust watering habits, ensure proper sunlight and soil conditions, and consider using a balanced fertilizer. If the issue persists, consult a gardening expert for further assistance.
