During blossom and fruit set, lower N amounts and higher P and K is usually suggested. N will cause wonderful greening and lots of vine but no fruit.

A question: is "too much nitrogen" relative to the amount of K and P? In other words, if I have high K and P, but low nitrogen, can I hit "too much nitrogen" while still having less in in my soil that P and K?
