The general idea behind most fertilizers marketed to homeowners is to have them buy as much as possible.
Honestly there isn't a set program for fertilization: a very general rule of thumb is that most crops will get two or three applications of all purpose NPK fertilizer throughout the season PLUS a certain number of applications of foliar/liquid nitrogen-free fertilizer once vegetative growth is underway, but without knowing soil and weather conditions (cold weather may reduce nutrient uptake, especially nitrogen, to say one) it's hard to say and to make things worse different cultivars may have different requirements.
I don't know what that organic fertilizer has in it (pixie dust? Leprechaun tail? Sugar, spice and everything nice?), but I concur with you those dosages are not merely excessive, but insanely so: even eggplants, one of the most nutrient intensive crops, take far far less fertilization. Post a picture of the label so we can get a look.
