fan leaves have tiny dots

Soil plants being fed with earthworm castings and roots organic fertilizer

almost a month into flowering and the buds looks good but many of the fan leaves are covered in tiny dots. There are no bugs to be found (i have looked with 30x magnification including under the leaves) and the dots don’t wipe away.

could this possibly be thrips?

Yes but mite damage can look similar

No and I use DrZymes
In flower you are pretty much too late

damn, might try to trim off some of the fan leaves than and hope the bugs won’t get to out of control by harvest time.

Maybe Thrips?.... get a good scope, and have a look on the bottom of the leaf.

You sure you didn't foliar spray anything ?
