I find camellias are generally more tolerant of lime in the soil than azaleas, Pieris, rhododendrons etc. in my neutral soil camelias do very well. Aspect, quality of soil and moisture levels make a big difference too.
Re those white patches on your flowers greenspinnaker I wonder if mildew is a factor. Are leaves affected too?
