I have this on several brugs in my greenhouse. I have searched and can find no leaf fungal pictures that resemble this, although my best guess would be some type of fungus problem. I plan to remove all effected leaves and spray with antifungal, but would really love to know what it is. Does anybody have any idea what this could be?
Mary, any chance they got burned? Maybe from touching the side of the greenhouse?... Or maybe because they didn't get hardened off properly? It looks just like the scorch I get when leaves get too close to the hot lights. It looks like environmental damage to me...
I am wondering if they got electrocuted. I have a bench below the bench these were sitting on, and there is a fluorescent fixture underneath this bench. This bench doesn't have a solid top, is wire mesh, so when I water, water drips onto the fluorescent fixture, and once I put my hand on the wire mesh and felt a slight shock. I thought I had that fluorescent fixture sealed off real well, but must not have. I turned that light off after I noticed that.
