The information is out there.
I don’t think I’m kidding.
I am using Epsom salts and gypsum mainly for their ability to lower pH in growing mediums.
everything I can find says they ~do not lower pH, let alone going over the science, application rates, etc. of using them to lower pH.
why do people using Epsom salts in soil ~stop getting blossom end rot? Because it lowers the pH of their to high pH soil to the appropriate range for the plants they are growing. I know, I have experienced it myself, it is a pH issue. Obviously a bag of soil has the nutrients required for a seedling but if the pH is not good for the seedling, the nutrients are meaningless.
10 million articles, none with what I requested, which is fine. I’m doing it myself.
I have looked at quite a bit of stuff trying to find application rates for gypsum and Epsom for lowering pH, I can’t find anything decent. I believe epsoma (I think is the brand name), has a product with either Epsom or gypsum or both, for lowering pH, been meaning to look at it, other than that, I’m over looking for it.
If you can find pH adjusting using Epsom or gypsum, with the science attached, I’d be impressed. Not a request though because I don’t think it’s there to be found.
