• Deficiency symptoms:Dark green or purple discoloration of the leaves, delayed flowering.

Potassium (K)

• Function:Improves the overall health and resilience of the plant.
• Deficiency symptoms:Brown leaf tips and edges, weak growth.

Calcium (Ca)

• Function:Strengthens cell walls and supports root health.
• Deficiency symptoms:Deformed new leaves and weak roots.

Magnesium (Mg)

• Function:Promotes photosynthesis and activates many plant enzymes.
• Deficiency symptoms:Yellowing between the leaf veins, slow growth.

Sulfur (S)
