Just for my reference - it hits on my question of how fertilizer actually works, butt this part is just for safekeeping:
'Mobility of nutrients: Deficiencies in mobile nutrients (like nitrogen, phosphorus, and potassium) will appear in older leaves first because the plant moves those nutrients to younger, still-developing leaves. Deficiencies in immobile nutrients (like calcium, iron, and boron) will appear in younger leaves first because the plant cannot easily move those nutrients from older leaves.'
