[OGD] foliar spray fertilizers

[Richard Buchanan]

Have we visited this topic recently? Sorry but I didn't use foliar spray 
until recently [WONDER GROW]. Believe I've read that plants can't utilize 
organic nitrogen, until it is broken down by bacteria & fungi in the 
soil/compost. Many of my Pleurothallids are mounted. The mounts are of 
course not sterile; but, would it be better to use an inorganic fertilizer 
for mounted plants? (i.e., MSU?).
Are all inorganic fertilizers suitable for use as foliar spray?
