In the pot I see small lumps that look like rocks, but they crush like dirt. Additionally, there's fuzz on the main stem that looks like a spider's web. Finally (what a brown thumb I've got) there's what looks to be red-orange creep near the base of the plant.
I'm pretty sure it's got web blight, but I'm a new gardener and wanted to be sure.
