Mites? Or?

No oozing. I'm familiar with them too. A severe infestation brings webbing with it. No streaking on paper, no oozing, no webs, and no lights. I think I've harmed it by spraying it so much. I realize sunburn can occur without sun and so I wonder if just setting outside burnt it. I haven't killed or had a struggling plant in a long time, this was a fave too. I am puzzled and bummed. Your input was helpful. Thank you.
