Hello everyone. I just purchased a soil pH tester from home depot, was about $20. Now I have a problem. When I stick it in water and let it sit, the pH is very low so I add baking soda to raise it but that lowers it even more! I thought maybe they had the wires backwards so I add vinegar and that lowers it too. However whenever I stick it in my soil, it says i have a pH of 6.5. Has this happened to any one else? Can these things not be put in 100% water?
Thanks
Thanks
