The standard conversion scale is the 700 scale (or .7 scale, same thing). Because of the 3 different ppm scales, I only use EC as my measurement. It solves a lot of issues and I recommend doing the same.

Compost tea pHGazillion recipes on line. But my question is about pH. What should the pH be? Is it advised to try and raise or lower it with G.H. up/ down or try silica or lime. Not finding recipes that cover pH adjustment or concerns. I worry about liquids. I've got a bottle of silca blast.

Ph of biobizz solutionMy tap water is usually at 7 / 7.3 PH and I usually drop it to 6.3 / 6.5.
Today when I did the mixture of biobizz nutes, the PH dropped to 4 or less.
What should I do? I have read to not mess with the ph of organic solutions.
I’m using biobizz light mix soil
