What the MSU fertilizer looks like?

I am not very happy with my fertilizer so I bought 1 pounds of MSU fertilizer on the internet to test my seedlings. I believe that there are not much companies make MSU fertilizer. I want to know that my fertilizer is the same with your fertilizer or not? My fertilizer is light silver white powder but when it dissolves in water it's green-blue color.
The mixture looks good except few tiny dark yellow which I believe the minor-elements. When I mix with water a tiny tiny amount is not dissolve (may be it takes more take time to dissolve but I can't wait). Question: my fertilizer is the same with your fertilizer or not? I hope I did not buy a fake MSU. Love to hear from you.
