Well, it is certainly possible for the values to be below what the kit can read, yes.

Whether that is actually true or you are using it incorrectly, however, I cannot know.

I did the tests 3 times just to make sure. I think i might try getting a water sample from someone else s tank

Yes, you can certainly have levels below the bottom couple of colors on those charts.
