Why Have Some Leaves On My Contoneaster Lactus Hedge Turned White?

In last few days I’ve noticed some leaves (particularly at bottom of hedge) on my 6 foot cotoneaster lactus hedge have turned/are turning white. Hedge is 8 years old and has always grown well. We live by the coast but hedge is sheltered by the house.

This looks to be an iron deficiency. I would check for deficiency or pH swings, which can cause deficiency-like symptoms.
