Pattern progression

Watch how the cue develops.

Paling can become more noticeable across new leaves while established foliage remains comparatively less affected.

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.
