Hi Courtyard and welcome to GoY. We need more info... is this a Camellia that you have planted recently in which case it possibly needs more water or an established Camellia?

I agree,more info needed..Is it in a pot,and if so,it could be too small for it,or is it planted in the ground,and what kind of compost?

A photo would help - whole plant and close-up of affected leaves.
