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.

Should I test plant tissue or cocopeat for a nutrient problem?
These tests answer different questions and often work best together.

Why the root zone matters
A substrate test describes the root environment; tissue analysis helps assess what the plant contains.
01 / OBSERVE
Three checks before you change anything
- Record symptoms and growth stage
- Ask the lab which plant parts to collect
- Pair results with water and feeding records
02 / NARROW IT DOWN
What is the main question?
Choose the closest observation for a suggested next check.
Which ions are in the medium?
Request the appropriate substrate analysis.
Is the plant taking up nutrients?
Discuss tissue sampling with the adviser.
Cause remains unclear
Plan coordinated water, substrate and tissue sampling.
03 / TAKE THE NEXT STEP
Leave with something useful
Use the lab's crop-specific sampling instructions and interpretation.
Keep in mind
Do not compare different leaf ages as if they were identical tissue samples.
