My curry plant (murraya koenigii) and my be kiwi vine (issai hardy) are showing similar symptoms. They were both inside for a bit, next to one another, before I hardened them for the outside. The curry is in a pot, planted the kiwi last week, and they both have yellowish leaves. Kiwi also has a couple of burnt-looking spots up top.

The curry plant should be glossy deep green and the kiwi should be a sprightly spring green. Something has gone wrong, and I am a total amateur and have no idea what.

Related problems? Or not? And either way, what IS it?
