Lee,,a couple of questions.
how long have you had this? Is it newly planted? Is it in a pot or in the ground? If in a pot did you use ericaceous compost? Essential. Is it in strong direct sun? Wont like that? MHave you watered it? Too dry and it will react as it has. If your tap water is hard and you used this on your pieris it will hate it.
pieris need acid moist soil,,protection from strong sun esp in spring when new leaves are forming and protection from cold winds.
are there any leaves left? What do they look like?
