Maybe by a different test kit if it's paper...if it's electronic, make sure it's calibrated correctly. You could buy a "buffer" solution from your local grow shop and try your test kit out on that...if it reads anything other than 7, you'll know you have a bunk test kit.
well,for starter i use ro water,are you saying my ro water should read about sevenish and not 6 also do you mean calibrating solution that has 7.01 because i do have some of that stuff,can i use that or is that what you are talking about.i do have a ph pen tried calibrating it but seems to bounce around to much and every time i do try to cal it,it never stay there so i bought a ph kit because i am tight with cash at the moment and no its not paper strips its the solution kind that you put three to five drops in a tube with whatever solution,thank for the quick responses.
