Cannabis Nutrient Burn vs Light Burn: How to Tell the Difference
What is Nutrient Burn?
Nutrient burn occurs when plants absorb too much of a nutrient, often due to an excessive fertilizer application. This leads to leaf discoloration and can be fatal if not addressed.
Preventing Cannabis Nutrient Burn With a Feeding Schedule
What is Light Burn?
Light burn happens when cannabis plants are exposed to too much intense light, causing leaf tips to turn brown or yellow. It's a sign of stress, but not as severe as nutrient burn.
Nutrient Burn During Flowering: What to Do
Identifying Nutrient Burn
- Look for brown or black spots on the leaf edges.
- Check for discoloration on the veins, which may be lighter than the surrounding leaf.
- Feel the leaves for a dry, crispy texture.
Identifying Light Burn
- Notice brown or yellow tips on the leaf edges.
- Observe the leaf tips for a curled or withered appearance.
- Check if the plant is positioned too close to a light source.
Preventing and Treating Burns
Prevent nutrient burn by using the correct fertilizer ratios and adjusting pH levels. For light burn, move the plant further from the light source and ensure even light distribution.
