Same, I don't fertilize until I know I have a good stand already started. Just too expensive to throw all over your dirt if nothing you planted is going to grow.
I often fertilize right after spreading seed, just ahead of a rain. Have also waited until right after I have germination, but then I kind of hate running over those fresh sprouts.

Best way to ensure healthy growth is to make sure you have proper soil amendment in your pH requirements. I've never considered fertilizing until you're in the growth stage.
