Are you sure you didn't accidentally mix up your nitrate and pH tubes?
I think the colors look like they're switched. The tube on the far left looks like ~5ppm nitrates, and the tube on the far right looks like ~8.0-8.2 pH (very normal for tap water, many cities have naturally hard water).
Also make sure you're filling the vials to the 5 ml mark.
Does not look like your cycle has even started if the tank has only been running a week. You need to either add an ammonia source, or get some filter media from an established tank to add to your filter.
