I started fermenting in the lab for a month or so and was feeding it while adding sulfates but in the end I had a 1000L mother brew up top on a stand when it’s below 3.4pH I let it down into 200L drums and add the sulfates without food I’d let it sit overnight or for a couple of days. I had do do this to handle the quantity of liquid as the application rate went up to move the needle on saps. It didn’t seem to make a difference with 10L fermented for a month or a night. Need to find a bio chemist to weigh in.

I’m aiming for 3% in solution with the citrics the iron is pH .33 and the manganese was 1.2 but won’t say too much until I get liquid analysis and saps back. Only the first trial last month trying to get the amount of liquid material handled back.
