Nutrient Deficiency Field Guide

Immobile nutrient / 04

Calcium

Newest leaves may emerge distorted or uneven, with localized spotting or lesions rather than an even lower-leaf fade.

Symptoms may appear first

Newest growth and developing tips.

Growlytics nutrient field guide chart for calcium, showing distorted newest growth and localized leaf lesions.
Use this visual as a reference point, then assess the full grow environment before drawing conclusions.

Pattern progression

Watch how the cue develops.

Fresh growth may continue to show irregular shape or localized damage as new leaves develop.

Check before acting

Look beyond the leaf.

Check pH, EC, watering, root-zone conditions, light or heat stress, and pests before acting. Visible symptom patterns can overlap, so this guide helps you investigate rather than confirm a diagnosis.
