    Default Lesion on C. aclandiae leaf

    Over a couple weeks, my C. aclandiae developed this reddish/brown lesion on one leaf:



    I sprayed it (and everything) with Physan 20 and it stopped spreading, but I don't even know whether it's fungal and it's still bothering me. The leaf is somewhat thickened there, bumpy, and not soft. The lower surface looks fine. I almost think it looks like sunburn, but my plants are inside, in a Western NY winter, and the blotch started when I had them sitting in the windowsill, before I moved them under a grow light, where they are now.

    The sun reflected by the snow has been very bright. It could be sunburn.

    It looks like sunburn to me. It is amazing how the snow outside is causing damage inside.

    We barely even have bright days here, either, but I guess the few we've had. . . have been pretty intense. Amazing indeed. Thanks all!

    Yes, looks like sun burn. Sorry. It should not be a big deal though.

    Cheers,
