Troubleshooting worksheet
Yellow new growth
The youngest leaves emerge pale, yellow, or green-veined while older foliage remains darker.
Look before acting
A visual match narrows questions. It does not prove a diagnosis.
Compare the location, pattern, affected plant parts, recent weather, watering, and changes in care before choosing a response.
Possible causes
Keep the list open at first.
01High-pH nutrient lockout
02Root damage
03Waterlogged or cold soil
04Micronutrient imbalance
05Herbicide or disease injury
Questions to answer
Look at the whole plant and root zone.
- Are the newest leaves affected first?
- Is yellowing between green veins?
- Has soil pH been tested?
- Were roots recently disturbed or flooded?
Low-risk actions
Change one thing at a time.
- Check drainage and root-zone temperature.
- Review reliable soil-test results before adding nutrients.
- Compare the exact pattern with crop-specific extension images.
- Remove only tissue that is fully dead.
