Oozleanswered grow question 2 years ago They are different products, so you can use them all.
Voodoo Juice is bacilllus bacteria (4 strains I think).
Great White has a shit ton of stuff in it, to include the bacillus strains in the voodoo juice. https://plantrevolution.com/products/great-white
I like to use the great white when I transplant and apply it directly on the roots. It is important to get your myco colonies set up early as that will give you the most benefit. So really I use it once or twice per grow.
The myco chum will work with any almost any product. It is only kelp, humic, fish stuff, and molasses.
Make sure whatever nutrient line you are using doesn't already have a humic/kelp product.
