Key takeaways:

• Commonly affects cannabis plants.
• Can be caused by nutrient deficiencies.
• May result from poor soil drainage.
• Early detection can prevent serious damage.

What it is / How it shows up:

Chlorosis is a common issue seen in cannabis cultivation, often mentioned in growing guides and forums. It appears as a yellowing of the leaves, starting at the tips and progressing inward. This condition occurs when plants cannot produce enough chlorophyll, the pigment responsible for their green colour. Causes can include nutrient deficiencies, such as a lack of nitrogen or iron, waterlogged soil, or root damage. Proper diagnosis is crucial to address the underlying cause and prevent further leaf damage, which can impact overall plant health and yield.

How it’s measured or identified:

• Visual inspection of leaf colour.
• Soil pH testing.
• Nutrient level analysis.

Use in context:

• "The chlorosis on my plants was due to low nitrogen levels."
• "Improving soil drainage helped reduce chlorosis."
• "Chlorosis is often a sign of nutrient imbalance."

Safety & compliance in Canada:

• Ensure proper nutrient balance to avoid plant health issues.
• Follow local guidelines for cannabis cultivation.
