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.

Why are bubbles visible in the injector suction line?
Persistent air entry can interrupt stock delivery even when water continues flowing.

Why the root zone matters
A coir crop can receive under-strength feed while the irrigation timer appears normal.
01 / OBSERVE
Three checks before you change anything
- Inspect the stock level and suction strainer position.
- Check visible fittings and tubing condition according to the equipment manual.
- Compare stock uptake and delivered EC during the affected event.
02 / NARROW IT DOWN
What accompanies the bubbles?
Choose the closest observation for a suggested next check.
Low stock level
Refill with the correct batch and follow the approved priming procedure.
Loose or damaged tubing
Have the line repaired and verify injection before normal use.
No obvious external fault
Arrange injector servicing rather than increasing stock concentration.
03 / TAKE THE NEXT STEP
Leave with something useful
Record the event and recheck both stock consumption and outlet EC.
Keep in mind
Do not compensate for air entry by making a stronger nutrient concentrate.
