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 a small irrigation zone affect fertiliser injection?
Check whether the injector operates accurately at the smallest zone flow.

Why the root zone matters
Young or partially filled coir zones may draw less water than the dosing equipment needs for stable operation.
01 / OBSERVE
Three checks before you change anything
- Compare actual zone flow with the injector’s specified operating range.
- Verify dilution during the smallest and largest intended zones.
- Record any pulsing, missed strokes or unstable final-feed EC.
02 / NARROW IT DOWN
Which zone fails the check?
Choose the closest observation for a suggested next check.
Only the smallest zone
Ask the designer to adapt equipment or zoning without overwatering plants to satisfy the injector.
Every zone
Review calibration, stock supply and installation faults.
No measured failure
Keep the verified flow range in the operating procedure.
03 / TAKE THE NEXT STEP
Leave with something useful
Recheck after removing plants or changing emitter counts.
Keep in mind
Do not assume an injector calibrated at high flow remains accurate at every lower flow.
