At some point you'll get microelement deficiency, when P is super high. It's a few years until that happens, so I wouldn't worry about it, that soil will need replacing anyway.
I use a 7-3-10 organic, not exactly sure how they managed to get that formula with so little P considering they say it's chicken based. But it does have vinasse, which is probably the best organic fertilizer additive for tomatoes since it's mostly K.
