Yellow leaves on my camellias.

Question

Hi
I grow a few Camellia plants in large pots as my garden soil is unsuitable being very alkaline. This year I have noticed the Camellia leaves have turned quite yellow. I think I remember reading somewhere that you can foliar feed Camellias with Epsom Salts to rectify this problem. I wonder if you can confirm this is true.
Kind regards
David

This could be a watering issue, nutrient problem or even pests or disease.
