Pattern progression

Watch how the cue develops.

The fade may become more visible across older foliage before newer growth shows a similar pattern.

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.
