Thereâs a school of thought that says let the aphids be, because the aphids will attract predatory insect species that will control them. Aphids are like candy to beneficial bugs. If thatâs not your thing, aphids are easily killed with a soapy water spray. A teaspoon (5-10 ml) of dish detergent in water should do the trick.
Your leaves look like might be dealing with something smaller like a spider mite or thrips? Keep an eye on the underside of the leaves and use a hand lens to magnify if you need to.
Another idea, the leaf holes remind me of the kind of damage you get when water droplets sit on the leaves and the sun comes out, then you get little burns from the water droplets magnifying the sunshine.
Good luck growmie! I hope this helps.
