your water should be fine, if it isn't there may be something in your tank affecting it.
As there is no fish you should have zero ammonia, nitrite and a low reading of nitrate. Your pH will be waht it will be! obviously, a pH of around 6.50-7.00 will allow you to have a good selection of fish.
Good luck with your cycle, only introduce a few fish and leave them for at least three weeks. In this time your tank should start cycling.
There are posts on this site about fishless cycling (a more fish-friendly way of cycling) check them out.
I did a fishless cycle, it took 4 weeks of having no fish (alot of patience) only to lose a Plec after I had him for three weeks

prob my fault, I dont think he had enough to eat!
Cant really recommend what type of cycling method to use, I think both are just as good, at least with cycling with a few hardy fish you'll have something to look at. Although you will find this type of cycling is unpopular on this forum!
