The concentration of nutrients in your hydroponic nutrient solution is usually measured by the electrical conductivity of the dissolved minerals in the water. The unit of measure is parts per million (ppm), but this only measures the total conductivity of the solution, not the relative strength of the various minerals. This is another reason why most hydroponic nutrient solutions are sold as a mix of 3 parts instead of by individual nutrient. Once you have the correct mix between the parts, it is easy to add to or dilute the solution to achieve the correct conductivity.
