The ratio of the three primary nutrients, Nitrogen (N), Phosphorus (P), and Potassium (K), that are present within a fertilizer, and are essential for the healthy growth of cannabis and other plants. The ratio indicates the proportion of these nutrients in fertilizers and is crucial for different stages of plant development. Each element plays a specific role in the plant’s growth, and the ideal NPK ratio may vary depending on whether the plant is in the vegetative or flowering stage.
