ph tested my soil

just ph tested my soil with this pretty shitty add and shake device where you add a soil sample with some powder from a capsule, add water, and observe color. i'm guessing the color mine turned was somewhere between 6.0 and 6.5 ph. is this too low, too high? if so what's an easy way to treat it.

Its fine. a PH of 7.0 is neutral. MJ is an acid loving plant and you are on the acid side of neutral. If you go too high or too low, it will affect the plant's ability to take up nutrients.
