So, my soil has low magnesium, and medium levels of calcium, it looks like those are what I need to look at adding first. Now my question is do I have to be concerned about throwing my Sulphur up way to high from the Epsom salts and the gypsum? My PH is already 7.1 so I can't just use dolomitic lime for it, otherwise I would, and I can't find cal-mag in granular format here, only in liquid which won't really work to ammend the soil, so any thoughts? Will there be a problem if I add too much Sulphur? Does Sulphur leach fast? Is there another product I'm missing that can add this stuff for a similar cost without all the sulphur?

Elemental sulphur will in time lower pH which may or may not be of benefit depending on if you need to lower or raise pH.
Rest assured that when added as magnesium or calcium sulphate the additional sulphur won't be a problem at all, nor does it affect pH.

I knew it didnt effect PH because the calcium/magnesium makes it higher, the Sulphur just balances it. However, I thought that maybe the Sulphur could lock up other soil nutrients if there was too much? But that sounds like it will be fine so i appreciate that!
Its just I've got a ton to add as my calcium is 1800 ppm and my magnesium is like 140 ppm so i have a long ways to go for both

Check out Vinemann's diary. He has a large patch with low calcium so he added 3500 lbs of gypsum. The suphates did not hinder him from growing a PB of 2301 lbs.
