Rolymo,
Those numbers are all different ways of saying exactly the same thing. Those are just the General Hardness values measured on different scales, kind of like those banners that show the word "Hello" in 5 different languages. Looks like you water is fairly hard. Not a big deal right now.
In any case, General Hardness, which is a count of the combination of Calcium and Magnesium have nothing to do with EI dosing, which is all about Nitrogen, Phosphorous, Potassium (NPK) and trace metals such as Iron, Zinc, Copper and so forth. There is no relevance. Dose per the instructions on your Starter Pack, and if you have the time and patience, you should thoroughly read the thread EI DOSING USING DRY SALTS in the Tutorial forum section.
Cheers,
