Arvum Plant Labs Chain of Custody FormNutrient Water Analysis | Dial‑In EC, pH & Ion Ratios
Nutrient Water analysis is used to determine the concentrations of nutrients in a mixed solution of multiple fertilizers diluted with water.
This confirms that mixed feed actually delivers the target ppm of each ion after concentrates dissolve in local water. Highlights hidden sodium, chloride, or carbonate buildup.
When Should I Do A Nutrient Water Analysis?
Growers should consider nutrient water testing:
- After tweaking formulas or additives
- Monthly for recirculating systems
Nutrient Water Analysis Example
- Finding: Chloride at 90 ppm (target <50 ppm).
- Action: Add RO pre‑filter, reduce cal‑nit addition by 10%, and retest in two weeks.
What To Expect: We will ship the appropriate sample holder and accompanying instructions, along with a prepaid return label, if requested, for sending it back to our facility. Test results will be available within 2 to 3 business days after which one of our Cultivation Advisors will contact you to discuss the next steps.
