switch to cococoir...switch nuts too?

i've decided to plant all my future crops, starting with this batch of seedling, to coco coir. I've never used it before so i'm a little scared to just add my regular nuts.

the guy at the hydro shop said to switch to something along the lines of monkey juice A/B but i can't see how in soil i have to used all these different products to accomplish what i want done and in coco coir i only need this solution. How can this be possible?:wtf:

anyone who's can shed a little light on this info for me i would really appreciate it thaxz in advance.:thumbsup:
