When should I induce N deficiency?
In the wonderful thread in the Houseplant Forum on converting an avocado tree to a houseplant, I mentioned that I have been using a complete, soluble 20-10-20 fertilizer on all my houseplants but wanted to change to a fertilizer with a 3-1-2 ratio as a result of reading the Fertilizer Program for Containerized Plants II thread started by tapla (Al).
In response, Al told me not to discard the 20-10-20 because, he wrote, "There will be times when you want to intentionally induce a N deficiency, and using a fertilizer with a 2:1:2 ratio is a very good way to do it. Changing ratios doesn't really do anything for you (the plant) though, unless you actually ARE reducing the amount of N the plant is getting to the point of mild deficiency."
He specifically mentioned growing tomatoes in containers. My question is, why would I want to induce a deficiency of any nutrient in container plants?�And how should I do that?
