Millilitres of prepared CropSalt concentrate per gallon of water. Every concentrate runs at 30 mL per gallon — the same as a 1:128 injector setting.

Timing
Vegging longer than 4 weeks? Repeat the week 4 rate.
Flowering longer than 9 weeks? A 9-week cycle runs Cake for the final 2 weeks. On longer cycles, keep Bloom A+B going until the final 2.5 weeks, then switch to Cake alone at 30 mL per gallon through harvest.
Mixing + EC
Prepare stock with the Stock tank + concentrate mixing guide. A + B together (30 mL/gal each) read EC 2.1–2.5: 1050–1250 ppm (500 scale) or 1470–1750 ppm (700 scale). Tap or well water may read higher.
RunClean
Use 0.2–0.4 mL per gallon as a descaler. When using RunClean in place of pH Down, add it until you reach your target pH.
