Nutrient deficiencies can significantly impact the health and yield of cannabis plants. For San Francisco cultivators, recognizing and correcting these deficiencies is key to maintaining a thriving garden. Let’s explore the common nutrient deficiencies in cannabis, their signs, and how to remedy them.

Identifying Common Nutrient Deficiencies

Nitrogen (N)

• Signs: Yellowing of lower leaves, stunted growth.
• Solution: Increase nitrogen-rich fertilizers.

Phosphorus (P)

• Signs: Dark, bluish-green leaves, purpling stems, and leaves.
• Solution: Adjust with phosphorus-rich nutrients.

Potassium (K)

• Signs: Yellow leaf edges, brown spotting.
• Solution: Supplement with potassium-heavy nutrients.

Calcium (Ca)

• Signs: New leaves are distorted or irregularly shaped.
• Solution: Add calcium through lime or gypsum.

Magnesium (Mg)

• Signs: Yellowing between the veins of older leaves.
• Solution: Apply Epsom salts or magnesium-rich fertilizers.

Iron (Fe)

• Solution: Increase sulfur in nutrient mixtures.

Factors Contributing to Nutrient Deficiencies
