KH really isn't important unless your KH is 0, even if it is it doesn't pose many problems for the plants because you will be dosing ferts, or do you mean NPK?
NPK stands for nitrogen, phosphorous and potassium, each letter stands for the each element on the periodic table.
We dont really need to test for P or K but we can test for P if you wish.
In the Us you have a product called flourish, which is made by seachem, its an all in one fertilizer bar one nutrient...phosphate. However you tap water may contain enough phosphate so you wont need to worry about dosing additional Phosphate.
As long as you have enough of each nutrient, your plants will thrive, keep your photo period short for the first few months (4 hours a day) and then once the plants have fully established themselves you can up it to 6-8 hours a day.
