I am about to buy the necesary items, but I am stuck without the knowledge of properly PH'ing my plants soil. I am using soil as my medium.
Can anyone tell me the exact directions for testing the ph with this

Also I am going to buy a PH meter to stick in the soil. I know I need to test the nuted water, either raise or lower the PH with up or down PH. but how do I adjust the soils PH level?
