I wouldnāt say this is any kind of pests. But it seems like you are starting to get a calcium/magnesium deficiency.
I would recommending adding calmag to your feeding.
There is plenty of products out there organic or synthetic. There is calcium magnesium in dry feeding and liquids so whatever suits you.
But be careful with it, if you over feed it you will burn your plant.
And lower the dosage when you enter flower.
If it would be pests I would recommend buying Neem oil, itās super good to all kind of bugs! Itās always good to have at home in case of emergency.
And if you donāt want to use Neem oil you can always get your hands on Lady bugs. They eat all king of leaf pests.
Good luck āŗļøšÆ
