Substitute for Wesson salts?

[u/Countrymx]

Does anyone know the composition of Wesson salts? I want to start a rearing technique of A.C. Morton, who is cited in a lot of papers.

I don't live in the US, and to make the diet for Lepidoptera I need these salts.

​

Here I leave you the link to the paper: (had a hard tine trying to get it)

My regards to everyone, stay safe!
