How to test for PH?

Got the solution ph tester. I basically have to add a bit of water and solution in a test tube give it a little shake and see the colour and match.

Question is, how do I test the soil's PH this way??

Do I take the run off? or gather a bit of the soil from the pot crush it with water and add a little solution?

Enlighten me

Thanks

Never heard of doing it like this. We normally just meter the water with a pH meter. Soil is very forgiving unless you really screw up.

But how can I know what the soil PH is? I mean, if there was a PH fluctuation in the soil, how would I know?

water to runoff and catch the first drips in your tube. Test this water. This is the ph of your soil. You want your runoff water to be aroun6.2-6.6

one more question, does iguana juice nutes make the ph go up or down?

all the nutes ive used have made my ph drop.
