I was just wondering how old the plant needs to be before i can start giving it some fertilizer?

Im brand new to all of this so i know im sounding like a real newb but im confused about the growth periodes. I know theres germination/seedling, then vegetation, then flowering. When does a plant start its vegetaion stage? Im guessing its as soon as it comes out of the dirt and gets its first node. Is that correct?
