please stop cutting leaves, the plant has nothing contagious. It's thrips, I'm very sure of that.
Blue stickers help to catch and indicate the thrips.
You can get rid of the thrips with nematodes (beneficial organisms). I had also suggested neem oil, but your plant is already very far into flowering, so I wouldn't use the oil anymore.
Good Luck 😎
