Can you give us a few examples of those nutrients?

Calcium deficiency can wreck a plant pretty quickly. It kills the meristematic (growth) regions. Potassium deficiency and magnesium deficiency cause the older leaves to die off. Boron deficiency is similar to calcium deficiency---the meristematic regions die.

N and P deficiencies have to last a lot longer and become a lot more severe before any parts of the plant die. The plants basically stop growing, but don't get damaged so much as delayed. They may be able to flower and produce some seed even though they are much smaller than they could be. _______________________
