Nutrient Solution Calculator
Calculate hydroponic nutrient solution concentrations (N, P, K, Ca, Mg) in ppm from concentrate dosage, solution strength, and reservoir size.
Inputs
Results
Nitrogen (N)
125 ppm
Estimated EC
0.55 mS/cm
How to Use This Calculator
- Enter the concentrate dosage (mL/gal) from your nutrient product label and the solution strength percentage for your crop stage.
- Enter your reservoir size in gallons to calculate the total volume of concentrate needed.
- Review individual nutrient PPM outputs (N, P, K, Ca, Mg) to verify your solution matches your crop's target profile.
- Check Total Dissolved Solids (ppm) and Estimated EC (mS/cm) — compare to your target EC and adjust dilution accordingly.
- Use Total Concentrate Needed (oz) to know how much of your nutrient product to purchase per reservoir change.
