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.

How can I check a fertiliser injector serving cocopeat?
Verify actual dilution rather than relying only on the injector dial.

Why the root zone matters
Every coir container in a zone receives the consequences of an incorrect injection rate.
01 / OBSERVE
Three checks before you change anything
- Follow the injector maker’s calibration method under normal operating flow.
- Record stock consumption and water throughput using compatible measurement units.
- Compare mixed-feed EC with the expected recipe after accounting for source water.
02 / NARROW IT DOWN
What does the check show?
Choose the closest observation for a suggested next check.
Ratio differs from the setting
Service and recalibrate the injector before compensating by changing the stock recipe.
Ratio matches but EC differs
Review stock preparation, source water and meter checks.
Ratio changes with flow
Ask whether the operating range and installation suit your zone demand.
03 / TAKE THE NEXT STEP
Leave with something useful
Repeat verification after maintenance or a major zone change.
Keep in mind
Changing both the injector setting and stock concentration at once makes the fault harder to identify.
