Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Can I use hard water to irrigate cocopeat?
Hardness is one part of water quality, not a complete verdict on suitability.

Why the root zone matters
Calcium and magnesium in water contribute to the total nutrient supply entering coir.
01 / OBSERVE
Three checks before you change anything
- Obtain calcium, magnesium, alkalinity and EC results
- Inspect emitters for scaling
- Review how the water contribution is included in feeding
02 / NARROW IT DOWN
What is the problem?
Choose the closest observation for a suggested next check.
Scale in irrigation equipment
Review filtration and maintenance with the equipment supplier.
Nutrient recipe ignores water minerals
Ask for a water-adjusted formulation.
Only hardness is known
Complete the irrigation-water analysis.
03 / TAKE THE NEXT STEP
Leave with something useful
Keep water treatment and fertiliser decisions linked to the same report.
Keep in mind
Hardness and alkalinity are related concepts but not interchangeable measurements.
