Buy an aquarium PH tester, the kind with the colour graph and the yellow liquid (cant remember the name). Use this to find out the PH of the water in your area, the PH where I am is just over 7, I need it to be 6 as I am growing in soil mix. I only add 8 small drops of PH down and this takes it to 6. To test soil ph without a soil ph meter (expensive) you need to buy some distilled water and flush your planting medium through. By testing the last drops of water to come out you get a good indication of your medium ph. Always remember - NEVER mix PH up and PH down as it is volatile and explaining the injuries may not be very easy.
