Yes - this is a new tank (2.5 weeks old) and have added some fish in phases throughout. I had used some media from an established tank.Looks like you have hard water, which is ok.
Your pH is rainbow color, which means the test is not really good for measuring pH.
Nitrite is high, meaning your tank is new, or hopelessly overstocked, or your fish are dead.
Nitrate is medium/high which is ok.
There is another possibility - that the all-in-one test kit isn't that good, and you might want to invest in some more precise liquid tests, at least for ammonia/nitrite if you are monitoring a new tank.
I understand budgets, but this is a MUST have. Instead of buying fish that could end up dying, save that money and get a true kit.Budget was tight thus I invested the $12 for the test strips to get all in one shot.

+1Don't add any additional livestock until you can get a more accurate test kit. Just to be safe.
