What's your carbon to nitrogen ration in the soil Zeroma? What % of carbon in your O and A layers? How thick are your O and A layers?
That is much more important than quibbling over NPK. Because carbon locks and holds and stores many nutrients and releases them as needed to plants. If you have enough carbon in humus form and watch your Ph, plants will seek out and find exactly what they need.
NPK is mostly important only when most the life in the soil is killed off, destroying the balance and the ability of soil to cycle nutrients. That's when we have to come in with artificial NPK "life support" for our tomatoes!
