Wendy, I didn't really want to speak up, because I can't really make a
helpful diagnosis from your pics. But I don't think it's pigment, nor
sunburn. If you are not seeing insect/mite problems on any other plants,
then I would have to guess fungus or bacteria. But coming down from the
points of the leaves like that would more suggest bug damage, at least to
me.

The yellowing lower leaves are most probably related to the other problem,
whatever it turns out to be. If not, they could be a sign of "too dry."

At minimum, I hope I've given your post a "bump" so that you can get better
advice. Kenni
