Cannabis Nutrient Burn in Flowering: Fixing Nutrient Deficiency

Understanding Cannabis Nutrient Burn

Cannabis nutrient burn, also known as nutrient deficiency, is a common issue during the flowering stage. It occurs when the plant absorbs too much of a particular nutrient, leading to visible signs of distress.

Causes of Nutrient Burn

• Overwatering: Too much water can leach nutrients from the soil, leading to a nutrient burn.
• Incorrect pH levels: A pH level that's too high or too low can cause nutrients to be unavailable to the plant.
• Excess fertilizer: Applying too much fertilizer can overload the plant with nutrients.

Identifying Nutrient Burn

Nutrient burn is easy to spot. The plant's leaves may turn brown, black, or yellow, and the edges may become crispy. If left untreated, it can lead to reduced yields and poor-quality buds.

2. Flush the Soil: If the issue is due to excess fertilizer, flush the soil with water to wash out the excess nutrients.

3. Replenish Nutrients: After flushing, add a balanced nutrient solution to replenish the depleted nutrients.

4. Monitor Watering: Avoid overwatering by ensuring that the soil is allowed to dry out slightly between waterings.
