I am about to start mixing dosing solutions from powdered fertilizers. I remember seeing a site that had a list of the max solubilties for the different ferts, but I can't find it now. Does anyone have a link to such a site?
 
Here it is.

Just remember that some are dry, some are mixed. It can be frustrating to get a solution until you realize that it should be mixed at time of dosing instead of in a pre-made solution.
 
Your other thread made me to pull out my chem book (thanks), and anything with NO3 and PO4 should have complete solubility. It's the stuff with SO4 and Cl that might cause problems, depending on the cation. Here's a good online table:
