California Gardening: Ailing white-flowered camellia in Riverside County, 1 by Grey_Sterling

My uncle gave me a lovely 12-year-old camellia with white flowers about two months ago. It is planted on the North side of the house where it gets bright shade for the entire day, until very late afternoon when it gets apprx. 1-2 hours of sun. We have terrible clay soil, so we added Amend to the planter in January when we first moved in (though it's still a lot more clayey than I would like).

It started off in a pot on the porch where it would get watered deeply twice a week, but starting looking a bit yellowy on some leaves, and some had brown centers. I thought perhaps it was not getting enough water, so I placed it in the planter where it would get watered more regularly. It has been looking more and more yellow/brown as the weeks go by, though it does not seem to be losing leaves.

I have fed it once with camellia food, a few weeks ago.

Looking at the state of the leaves, can anyone tell me whether I am watering too much, too little, if it's getting too much sun, or could it be disease? Would it help to put it back in a pot, or just stress it? He gave us another potted pink-flowered camellia that is on the west side of the house and gets apprx. 1-2 hours morning sun, and it is doing beautifully, but I'm worried I'll kill the white one by moving it needlessly.

I very much appreciate any help. Even if it is just to tell me there is a more appropriate place for this topic--I didn't see a forum for camellias. :)
