Cannabis macronutrients consist of nitrogen (N), phosphorus (P), and potassium (K), commonly referred to as NPK, along with secondary nutrients like calcium (Ca), magnesium (Mg), and sulfur (S). These nutrients play vital roles in photosynthesis, root development, bud formation, and structural health. Deficiencies or imbalances can lead to poor yields and weak plants. Growers typically supply macronutrients through fertilizers, nutrient solutions, or amended soils.
