My compost tea tests out at 7.9, so can guess why my garden is now 7.9?
Now I need some advice as to how to get my garden down to about 6.0 Ph. Anybody?
In the mean time I won't be using Compost tea.

I had a problem where my vermicompost was coming in at a high pH like that. In my case the problem was that I was composting a lot of egg shells in my worm bin.
Egg shells are ~94% calcium carbonate. They will make things alkaline.
That said, be careful adding acidic stuff to a compost bin. I know if you add citrus rinds you can end up with a fungal bloom. Supposedly you can add them in moderation. I added 1 rind and I had fungus everywhere.
but that was before I started composting egg shells so maybe I could have composted citrus rinds with egg shells.
I was just making vermicompost tea for a folear feed so I wasn't concerned with soil pH.
