I can't swear it's not a microscopic bug, but I have had the leaves undeer 90x magnification didn't see anything living.
So, for the sake of this thread, let's assume this damage in not from a bug, but something else.
The spots, like like the beginning of a Ca/Mg issue, but are the holes the end result of that issue, or are the holes some other issue?
I tried to get you as close as I could with my pics. These are leaves from two plants: Critical Purple & Gorilla Glue.
They live in indoors in excellent VPD conditions and they are under lights at the proper DLI.
They are both fed Jack's 3-2-1 at full strength, and supplemented with Cali-Magic in their 5-gallon pots of Coco/Perlite/Vermiculite.
They rest their bottoms in AutoPots, and get air pumped to their roots.
I am guilty of foliar spraying in the light, but close to before lights go out. So, I can't rule out light damage for the holes.
Tell me what you think?
