This is wot i would expect your tests to look like, shows that your ammonia has come come down to almost nothing and the nitrite would be sky high like this.
I would however recommend small water changes to dilute the nitrite if you are cycling with fish, otherwise the nitrite will harm your fish by them not converting the homogolbin which carries oxygen around the body, may see increased gill beats, listlessness, not feeding, gulping at surface for oxygen etc. But if you are cycling with no fish then it wont do any harm.
Think it can take 6 to 8 weks to fully mature!!! but dont go and buy stacks of fish all in one go, go for 4 small fish like daino's and then wait two weeks before adding another small amount of fish, just so that your tank stays nice and stable and you shouldn't get spikes of ammonia or nitrite.
