How do you balance , lower or raise ph in soil

If my Ph is my organic super soil is 6.5 and I want to lower it to 6.3 how do I fix that ? Do I flush and feed with 6.3 ph water or do I just feed with 6.0 ph water in hopes to lower ???

you NEVER flush SUPER SOIL to attain desired Ph levels, it just ruins the SUPER part of it. The only reason to flush would be a slat buildup / liquid nutes. To change Ph substrate, molasses and vinegar…molasses to lower, vinegar to raise

@Mrb53004, welcome back!

But isn’t it the opposite? I’ve never used either, so I don’t know the effect. But vinegar is acidic, and should lower pH. Unsulfered molasses is alkaline and should raise it.

Traditionally garden lime is used to raise pH and elemental sulfur is used to lower it - iron sulfate or aluminum sulfate.


I use day old coffee quite a bit as ph down. It has tons of tannins too. I have also used apple juice and orange juice quite a few times in the past. Coffee, OJ, and AJ all have a ph of about 4.0.

I like to use the juice over the vinegar because the juice still has all the sugars. I like my soil microbes to eat the sugars instead of the microbes that converted the fruit juice to alcohol and then the microbes that convert that to vinegar.

And to all of this do you add these to the soil itself or do you lower or increase ph in the water itself then in soil ???

Example if my ph now Is 6.0 how exactly do I raise it to 6.3

oops, but in opposite world! That is what my kids tell me all the time. I got it, even if it is backwards

I would not really try to change soil ph as it is self correcting in living and organic soils. Control what goes in to effect what comes out. When making substrates, if coco or peat are the 75% foundation, that can be different
