EC values are general crop references, not a measured result of this dose. Measure your mixed solution and ask for crop-specific advice if it is unsuitable. Never mix undiluted concentrates.

How to mix it

  1. Fill reservoir with 20 L of fresh water.
  2. Add 60 ml MICRO first. Mix thoroughly.
  3. Add 60 ml GROW. Mix thoroughly.
  4. Add 60 ml BLOOM. Mix thoroughly.
  5. Measure EC and pH with calibrated meters; maintain tank pH at 5.5–6.0.
  6. If the solution is unsuitable, check source water and mixing accuracy and seek advice rather than changing the bottle ratio.

Understand what the calculated amount means

What a calculation cannot measure

The calculator scales the current directions to the water volume entered. It does not analyse water, predict final EC, verify a batch or diagnose a deficiency. Enter actual water volume, not the tank capacity, and measure each part separately.

Check the finished mix with calibrated meters. If measured EC differs from a crop reference, check water quality and mixing accuracy and request advice. A correct millilitre calculation is one step in nutrient management, not a complete crop prescription.
