Yeah that could be some of it!
(I still vote for that for punctuation).
I was thinking and yeah it may have come off that I thought they were beneficial but it was not the case just trying to compare it to my situation and confirm what I had going on. While they look like those I have never seen them on the undersides of leaves like that. I don't see them on the plants in soil but in the coco setup they do although I have never seen any type of food for them on the plants
Just assumed since it was the coco setup they couldn't find what they want in there so they move up the plant
