The thing about nutrition is that you need to match the needs of the plant, the plant will generally do what it wants. So, for example, if you have lots of growing fruit, and want good upper plant growth, you need to come with lots of potassium, if there is not enough potassium passing the fruit, the plant will not grow even if it has nitrogen.
