Also called / Category: Leaf tip burn, Leaf scorch / Pests, Pathogens & Disorders
Key takeaways:
- Tip burn is most commonly caused by excess salts or nutrient accumulation.
- It often occurs in nutrient-rich environments or with improper watering practices.
- Affects the plant's aesthetic appeal and can indicate stress or suboptimal growing conditions.
- Tip burn can be a sign of over-fertilization or poor ventilation.
What it is / How it shows up:
Tip burn is a term frequently seen in cultivation discussions, store reviews, and grow guides. It appears as a brown or burnt look at the edges or tips of the leaves and is primarily due to nutrient stress or environmental factors like low humidity or high temperatures. When the plant absorbs more nutrients than it can process, excess salts accumulate at the leaf tips, causing cell damage and browning. In cannabis cultivation, managing the nutrient balance is crucial to prevent tip burn, as it can affect the plant's health and appearance, which in turn might impact its market value.
How it’s measured or identified:
- Visual inspection of leaf tips for browning or burning.
- Monitoring nutrient levels in the growing medium.
- Assessing environmental conditions like humidity and temperature.
Use in context:
- "The tip burn on my cannabis plants might be due to over-fertilization."
- "Reducing the nutrient solution concentration helped eliminate tip burn."
- "Ensure adequate offset-4 transition-colors hover:underline" title="Learn more about Air exchange">air exchange to prevent tip burn in your grow room."
Safety & compliance in Canada:
- Ensure compliance with Health Canada's regulations on cultivation practices.
- Avoid excessive use of fertilizers to prevent environmental harm.
