Earth Juice Help

I purchased a bottle of earth juice natural up to offset the low ph of the ff tigerblood. My ph tester is crappy and trying to experiment with this crap is pointless until i get a better meter. Can anyone tell me how much tsp or tbsp ect they use to raise the ph .05 or 1.0 per gallon of water. Posted this in another section but no views or replies.

the GH liquid ph-test kit i mentioned in ur other thread is only $8.95 at the store by me

to move my nutes down one point from 7.2 to 6.2 I use one TBSP of pH down. But I use general hydroponics so I dont know if the strengths are the same or not.
