Name that nute...

I have several types of fertilizers lying around the house:
-for bougainvillea (in granules): 7.6-15.2-15.2
-for "tropical plants" (especially banana trees/also in granules): 10-20-20
-Miracle Grow houseplant formula (liquid): 8-7-6
-Shultz's Orchid food (powder to be mixed with water): 19-31-17
-Peter's Bloom Buster (powder(?) looks like regular blue Miracle Grow grains):
10-50-10

I know that there are better ferts out there, but can any pros/semi-pros out there suggest a decent regimen (vegging & flowering) from the list above? I'm scared of using the first two...since they come in granule form, I wouldn't have any idea how much to use.

Thanks.
