I have four different tomato varieties in my garden -- all of which were producing just fine for two months but them simultaneously came down with this white fungus on the stem that seems to turn the leaves prematurely rusty with yellow and black spots. I fear the plants are dying, and this will be my last harvest before I have to replant. If there's anyone out there who can diagnose this for me and offer a remedy, I'd sincerely appreciate it. I've included pictures at the web link below.
BTW -- I fear that the cause might be a hanging heirloom tomato plant I have above my floor planters that has been draining down from the soil up above. You can see pictures of my garden, the hanging (now stemless) heirloom plant, the white stem fungus and leaf damage at the link below.
Thank you so much for the help!
