I am in week 4 of outdoor grow. I’m in cloth pots about 3-4 gallon with organic soil composed of compost, coco coir, worm castings. I’ve noticed a lot of little flys in the pots and one of the leaves has been chewed on. Any organic natural deterrents or foliage spray that I can make to ward of the insects? I also noted some white spots on leaves. Not sure what that is or if it’s an issue. Thanks
