Hey there Khmma , that's from spider mites, you can tell from the sharp bite mark looking spots as well as the little black dots from under the leafs in one of the pictures. you can order live lady bugs online and these can eat like 10k spidermites a day each, but the problem outdoors is that they fly away, so you end up having to build like a habitat for them and even then they dont really stay there sometimes. Another thing you can do is to spray with bacilus thuriengiensis which a beneficial bacteria that paracites the eggs larvae and adults and eventually controls the outbreak quite well, but that can take up to two week so be patient. Spray it on towards the evening as the sun does degrade the spores , spray twice a week and once in the watering for like two weeks then it's just a matter of keeping up the beneficials every ten days or so. no harm to the plant and you can keep adding it until harvest. Hope this helps ! 🚀
