Nutrient Mixing & Dilution Calculator
Mix to a target EC, convert label rates to a reservoir recipe, or dilute a stock solution with C1V1.
Seedlings 0.4 to 0.8, veg 1.2 to 2.0, flower 2.0 to 2.8.
RO is about 0. Tap is usually 0.2 to 0.6.
From the label or manufacturer data. Typical 0.1 to 0.5.
Any unit (mS/cm, ppm, %). Use the same unit for C2.

Add nutrients to water, not water to nutrients. Multi-part: Micro first, then Grow, then Bloom, stirring between. Verify with a calibrated EC pen.
Formulas
EC Target: ml/L per part = (target EC − water EC) ÷ sum of each part's EC per ml/L, with all parts dosed equally. Label Rate: 1 gal = 3.785 L, 1 tsp = 4.93 ml, 1 fl oz = 29.57 ml. C1V1: V1 = (C2 × V2) ÷ C1, water = V2 − V1.
