Why does lettuce develop tipburn in cocopeat?
Inspect the location of damage and the growing conditions before increasing calcium. Internal leaf injury may differ from external scorch or disease.

Why the root zone matters
Fast growth and water movement can affect calcium delivery even when nutrients are present in the root zone.
01 / OBSERVE
Three checks before you change anything
- Check whether damage begins on young inner leaves or older exposed margins.
- Review climate, airflow and growth rate during head development.
- Compare water and nutrient records with crop-stage guidance.
02 / NARROW IT DOWN
Where is damage located?
Choose the closest observation for a suggested next check.
Young inner leaf margins
Ask the crop adviser to assess tipburn and the growth environment.
Outer leaves only
Investigate exposure, salts and other causes using photographs and records.
Soft spreading tissue
Seek disease identification before treating the symptom as a nutritional disorder.
03 / TAKE THE NEXT STEP
Leave with something useful
Compare affected and healthy heads at the same maturity and location.
Keep in mind
Do not diagnose calcium shortage from every brown leaf edge.
