Good day Colin. You probably already considered dolomite, in the event you need Mg too…..

Are you seeing low sulfur on sap or tissue testing? What’s your OM%? As you might already know, Sulfur levels can be tied to OM. I cant recall whether the sulfur is a component of OM, hence potentially not entirely visible on M3 testing, or whether the OM just provides anionic exchange sites for the S to cling to. But if its the former your soil analysis may simply not be showing you the total nutrient pool…..
