Fertilizers and Applications

[Windy]

What brand of 20-20-20 fertilizer does the best job? I've found some on line, but it seems only the 20-10-20 actually says it's urea free (at least, from the few searches I've done).

I'm new and have been reading a bunch (lots of great info on OB), but I'm getting confused about how to apply fertilizer. Most say to add it to water when soaking. But, I've also read others mist it on. Which is best?

If I mist fertilizer, do I only do the roots? I'm very careful to avoid getting the leaves wet except to remove dust (then, I dry them).

Right now, I'm using Better-Gro's fertilizer (20-14-13) in every other a soak. I also have their bloom booster (11-35-15), but haven't tried using it yet. This brand is the only one locally available.

I'm so confused....
