Thanks folks, I'm definitely going to try the alcohol first, I'm really sensitive to chemical smells. Someone on the houseplant forum tells me that this may be spider droppings, and that seems plausible since there are webs on it, really messy webs like a black widow might leave. I'm not looking forward to any of this, lol.

Anyway you can supply a pic? I've seen a few diseases of coneflower, but you'll want to use your local Extension office for proper diagnosis.

Thanks for all your responses! I looked closely again at the leaves and I believe I have thrips. UGH!! There are some tiny yellow/orange super slow crawling things on the leaves. So mad! I have no idea where they came from, especially since I live in a high rise in the city and my window is only occasionally open to air out my plant. I made some homemade chili pepper (serano) and garlic spray and sprayed the plant...I hope that solves it? Man...growing a plant is a lot more difficult than I though it would be. ;p Fingers crossed the spray kills the thrips and not my plant.

Deva, I think it's just a reality we have to accept when growing outside. I, for sure, am not spraying anything near where my PvN is but it has some spots (scuffs!) like yours and my variegated jade...it's a lifelong mission trying to get it flawless. I will grow wings before I get it perfect and am considering bringing it indoors. I grow my share of jades indoors but never brought this one in. It drives me nuts. I prune the thing JUST to get rid of flaws LOL, but in turn it's grown bushier...not by intent. I just sent Lati a cutting because I was going to cut off another piece!
