The next 3 columns are the converted PPM values of the EC based on 3 different scales. Most high-end meters will show EC as well as multiple PPM values. Most inexpensive meters will only display PPM and usually in the 500 scale. PPM & EC. Knowing your PPM helps you avoid possible burning by letting you know when to adjust the amount of nutrient minerals you add to your water.

Microsiemens (μS) is the unit of measurement of electrical conductivity (EC) in water or other liquids. EC Values for Hydroponics and Soil by Week. Measure the pH level. If you choose to measure by PPM, hydro growers should begin with a solution that has 500 PPM and increase by 50 every week. The pH should be close to 5.5, and at least 5.2.

While TDS can be determined from EC, the two do differ which is why the conversion is only an estimate. You now have actually exceeded the manufacturers recommendation by 600 PPM @ 0.7 conversion by running at 3000 µS * 0.7 = 2100 PPM @ 0.7 conversion. To convert a PPM figure back to an EC figure is a simple matter of division.
