your pieris looks okish keenbutgreen but I would give it a couple of sprays of epsom salts soon.......
epsom salts is a great tonic for many plants but esp on pieris and the like. A thorough spray to run off in say february and again in April and another in summer.
I would also give it a thorough watering in early spring and a thick mulch....pine bark chips or ericaceous compost
it's what I do in my free draining soil
however, please check your soil...do a PH test. Pieris does need an acid soil and will not tolerate any lime. If your soil is acidic, check out Pieris Flaming Silver. for me it is the best variety....longer leaves with nice green and white variegation, superb bright red new leaves and white flowers.
if your soil is alkaline you would be advised to repot in ericaceous john Innes soil.
a PH test is simple,,cheap and quick. worth a test before you spend any money on another pieris
