Spots on Monn. millenium witchcraft leaves

[Michelle15]

My Monn. Millenium Witchcraft leaves have small spots on them. I repotted it as it was coming out of dormancy a couple months ago. I had it in a south facing (but shaded) window and the first 2 new leaves had a ton of spots. I moved it under my LED lights and the next leaves did not have spots, but now it's outside and those leaves are getting some spots. Outside it's under a tree and gets mostly morning sunlight.
I assume it's sunburn from too much light but it's pretty random. I did find a few spider mites on it the other day and treated the plant, but there were no obvious mites before it went outside.
I have attached pictures of the leaves with close-up of the spots.
