I think the mould will be a type of mildew and this combined with the drought will most probably be causing the leaf drop. Can you soak the base of the hedge? Spraying is no longer an option as you really need to spay for prevention, not cure. A slow release feed such as Q4 around the bottom of the hedge out to the dripline would be good too.
