The best fertilizer for chillies is a balanced, water-soluble fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK ratio of 20-20-20 or 10-10-10). Apply it every 2-4 weeks starting from when the plant has its first set of true leaves. Complementing this with a calcium-rich foliar spray can help prevent blossom end rot, a common issue in chillies. Always follow the specific dosage instructions on the fertilizer package to avoid over-fertilization, which can harm your plants.
