I hate the fuckers! If you thought you saw webs take a misting bottle and very gently mist around the stem. If you have webs You'll see them. I had feckles everywhere but I wasn't missing chunks of leaves like that, even the leaves they killed just got freckles on top of freckles till the whole thing was yellow with green freckles then they got crispy from the edges i evenly. But I'm a newby. Either way I wish you luck.
