Almost ANY highly nutrient-dense soil (as opposed to inert mediums) will change the pH-- that is why you MUST test the pH of your runoff when watering, and adjust the pH of your water to keep it under control.
Also-- those soils need something mixed in, vermiculite or pearlite, coco/coir etc... to fluff it up- otherwise they will be really dense and hard for the small hair-roots to penetrate... and hardens like cement when the top 2 inches dry out-- which is what ya are supposed to do-- wait till the top 2 inches dry then water deep enough for runoff.... and test it!
No need for revenge, just sit back and wait.
Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
