It depends if you are talking about chemical fertilizers or organic. It is 
hard to really overdose in organic fertilizer, if it is not fresh, and 
balanced. Heck, you can grow a pumpkin in pure compost. But of course if you 
put down fresh green grass or fresh manure, you will kill them in a day.
Chemical fertilizers can cause a lot of severe problems if used higher than 
what the label says. They can burn your roots, destroy all living organisms 
in the soil, contaminate ground water, etc. Basically at high enough levels 
it will poison your plants, because of the ammonia and other chemicals used.
Now if you mean overdosing as far as making the pumpkin grow too fast....I 
would worry more about water, as far as that's concerned. Water needs to be 
even out, and not surged or allowed to dry out. I haven't grown anything over 
300 pounds or so myself yet because my pumpkin got destroyed last year, and 
this is only my second year with AG's, but I do know a lot about gardening, 
so again I should clear up for other list members that I am only trying to 
help, using the knowledge that I have. (Which I think is a good amount). 
Sometimes people get angry when I try to offer advice to someone needing it, 
even if it is good advice.... go figure! Oh well.
