Yeah, they're there. I was looking at the slightly yellowed leaflets, but I needed to look at the good parts of the leaf, they left those pastures long ago. They look more like small worms, and the colour makes them hard to see (transparent and yellowish).
The most close of what I see is this picture on the internet:

The mites are already in the green leaf tip, and probably lots of other places on the plant.
This is gonna be a bad year
I don't even know where they came from, I'm on the third floor. Definitely not from the pots, since the damage started from up on the plant.
