earth worm casting Qustion please

after adding the solution of earth worm casting extract highly concetrated 5.2.2 liquid 100% natural makes the PH level very high . so to fix the ph is it possible that u need to add around 20 ml of viniger per 2 litre of water plus 20 drops of oh down to make ur ph 6.4 any help please.any advice how to use worm casting solution?

Im a newb but using pH down shud sort out ur problemo. mayb decreasing the pH of the liquid b4 adding it perhaps

the PH of your worm crap shouldent be high?
did you buy the stuff, or have a worm bin like I do?
the Ph could be high, depeding on what your feeding them

just add a little and dont go over board a little is more
