From your description this could be weather related or fungal infection.
Plants generally can recover from winter damage.
Fungal infections are quite common in damp spring weather but can attack plants at any time of year.
Left untreated the infections spread and the leaves turn black and drop off the plant.
A broad spectrum fungicide can be applied to the point of running off the plant.
Application can be once a week until the fungus is under control.
