Really depends upon the TYPE of fertilizer blend.

With more nitrogen in the mix, it will usually have more vegetative growth, postponing fruit production, this is something that I try to do when I feel that blooming will happen in the fall, so a month before that I would bump up ammonium sulfate.

with more Phosphorous in the blend, pup production is encouraged.

with more K in the blend, blooming is encouraged.

And then there are these various roles of micronutrients.

I apply nitrogen the least. I use 6-27-27 XB with minors from BEST fertilizer brand, it achieves a nice balance of growth, pup and fruit production.
