I have a small hoya collection and have noticed some strange leaf damage and spotting on several plants. On my Hoya carnosa, new leaves are often streaked and contorted. They also have small marks on them.

The other problem is on my Hoya wayetii. This one has white specs on several leaves.

There are no mealybugs and no signs of spider mite. All leaves are firm and there is no sign of rot or mush. The plants are fairly close to a double T5 lamp, though I haven't read of any problems for these varieties close to light. I let them get dry-ish before I water, they have individual thirsty lights.

I can't find anything that matches. Maybe scale for the wayetii, or thrips damage on the carnosa? These are the closest guesses I have.
