if its the only one... pull it off.. and forget about it ...

the leaf was damaged... and is slowly declining ...

if you were up north ... i would suggest frost or freeze ...

could be sun burn.. if you just bought it from a shaded nursery.. and blasted it in full sun ...

or it could have been damaged when you roped it to the roof like a dead deer.. for the ride home... lol

let us see the whole plant... if its not just that one leaf ...

As requested the whole plant - though it's still a small one.

I was just concerned because the leaf damage was happening to multiple plants. All plants are new to me - purchased this May or after. (So I don't know about the growing conditions before). In my yard, these plants have been repotted to slightly larger containers & are in pretty solid (not deep) shade. They have definitely not seen a ridiculous amount of sun.

but it cant be a disease.. with only one leaf ...

just pinch it out ... and forget about it ..

must have been the ride on the roof home ...

Thanks, Ken!

Thanks, Pieter. That looks like what I had/have this spring. It was
on my older plants. I assumed some kind of rot, so I washed off all the
soil and soaked the roots in 10% bleach. It slowed it down, but they
have not rebounded. I've almost lost Paradigm, OBL and Francee. I'll get
the appropriate fungicide and see if I can save them. I would guess the
really wet spring had something to do with it.

Thanks again, Pieter.
