Get a magnifier, look on the underside of the leaves for very small cigar shaped insects. If you see any, they are thrips and you are in for a headache. Get a bottle of Captain Jacks Dead Bug Brew or a spray with spinosad. Spray the affected plant and any other nearby or other soft leaved plants once a week for 6 weeks. That’s what it takes to get the adults as well as the larvae that hatch out from eggs in the leaves. Thrips fly so treat as many plants as is practical. For larger collections you can release beneficial mites which eat thrips.

I hope it’s not thrips.

Sundew are pretty robust. If it’s super dry they’ll produce less snot but given lots of light and distilled water they’ll eat lots of gnats. Enjoy the Hoya, let that guy dry out a bit between waterings.
