i don't think its thrips, i recently had them and they never made holes in the leaves. spider mites are the ones to watch for. get the magnifying glass out for sure!looks like maybe thrips, pull a mid level leaf, flip itover and blow on it, look at it through a magnifiying glass, thrips are the size of a pinhead.
you will need a magnifying glass to see them, they are sometimes transparent with just two tiny specs on thier back, i got some now little bastards , didnt realise for ageshow big r spider mites
