Do you use more than one nutrient?

I have some nutrients such as Organic-B1, Rhino Skin, Voodoo juice and bud ignitor from Advanced nutrients given from a friend but I don't know if I'm supposed to use all of this or just one, I've read that Voodoo juice is a root enhancer that you use only in the first 2 weeks of vegetation (first 2 weeks of the grow), I have no idea what the other stuff does!

Are these nutrients good for both hydroponics and soil growing aswell?

Many thanks

Some day when you have nothing better to do read the labels on your Advanced Nutrients bottles. You may be surprised at what info is there. I use about 15 of their products.

Another ah ha moment...ya buddy read, read, read...i bet if you put those names into a google search you would get your answers..g/l
