Nothing is wrong with your numbers....you haven't had time to cycle the tank yet, like I mentioned in chat. A cycle takes at the minimum, 4 weeks usually. Sometimes fishless cycling can be faster........but it won't be less than 3 weeks if you don't use any established media.
Prime won't affect your test results, so you didn't wreck it.
Keep adding the food, a little every day and then when the cycle is over, do a large water change.
