Leaf Necrosis
Leaf necrosis refers to the premature death and browning of leaf tissue, appearing as dry patches or margins on cannabis plants. This classification encompasses various physiological and environmental causes, including nutrient deficiencies (particularly potassium, calcium, or magnesium), environmental stress (heat, drought, humidity extremes), or pathogenic infection. Growers document necrosis patterns to diagnose cultivation problems and adjust feeding, watering, or environmental protocols. Breeders distinguish between genetic susceptibility to necrosis and environmentally triggered necrosis when selecting breeding stock. Understanding necrosis markers helps cultivators optimize growing conditions and maintain plant health throughout development.

Plant breeders track necrosis expression across generations to identify lines with greater resilience to environmental stress or specific nutrient uptake patterns. Selection for reduced necrosis susceptibility contributes to more stable, forgiving cultivars in diverse growing environments.
