Do sunflowers grow better with more or less fertilizer?

well, it really depends on the type of fertilizer you use, it has to be a special kind of it. if you use the no name brand than less fertilizer is good, but if you use famous brand names than more, if its a name that is not so famous, you would not want to much, maybe about 55% of it. say thank you to me because im giving you the info!
