My pumpkins are developing roundish white spots, has the appearance of
residue from minerals in water, but appears to be spreading. Alas, I fear
mildew of some sort. Anyone know of a cure for this? I hate to loose these
plants - they have quite a few green pumpkins and are growing quite
vigorously.
My gourds have also got white spot on their leaves, they are in
containers on an 18 story balcony facing west. in spite of this they
appear healthy but still I worry when I don't know what is causing it.
I only use organic fertilizer... but the soil might be exhausted. They
are heavy feeders. Any expertise would help.
Thanks,

I have a photo but I don't know how to post it.
