You may both be right. Soil pH affects the availability of many plant
nutrients. Iron is always in vast excess in soil (almost all soil, it
is one of the most common elements on earth, after all). But it is much
less available to plants at the wrong pH range. So you could
(theoretically) overcome the wrong pH by supplementing with additional
iron.
