What is a Nutrient Burn in Cannabis?
Nutrient burn, also known as fertilizer burn, is a common issue in cannabis cultivation. It occurs when plants absorb too much of a nutrient, usually from over-fertilization. The excess nutrient can interfere with the plant's ability to absorb other essential elements, leading to visible damage on the leaves.

Causes of Nutrient Burn
- Over-fertilization with nitrogen-rich fertilizers
- Using tap water that contains high levels of minerals
- Improper pH levels in the soil or hydroponic system
Symptoms of Nutrient Burn
Nutrient burn is typically characterized by brown, crispy leaf tips. The affected areas may also appear dry and feel leathery. If left untreated, the burn can spread to the entire plant, leading to plant stress and reduced yields.
