My oregano plant, I think it's a Cuban oregano plant, is sick. I'm trying to out why it's sick. It was initially grown in NY and was doing fine. It has always lived indoors and has been watered with one of those aqua globes and changed out. The leaves, ever since I have moved to Florida, have been dying and appear to be transparent in the center. Attached are some photos below, trying to figure out what's causing this.
