As a general rule, no.  
Nutrients from different sources often chelate when mixed causing them to form tiny pebbles or mica like layers in the bottom of the tank. This is a waste of fertilizer and may clog your equipment.  
Plus, if there are different ratios and dilution rates, you will have to do a lot of math to figure out what you are actually feeding.  
If you must, try a test solution in a gallon jug of water. Agitate and let sit for a day. Then check how it looks. If all looks OK,!then start calculating your EC and PH. If still good, just try it out on a sample plant before using it for the entire grow.  
Best of luck.
