I'm new to this forum, so Hello everyone. I just checked my garden tonight and my cukes leaves have white spots and my bell pepper leaves have brown spots. Do any of you know what this is?
It can be several things, it could be a nutrient deficiency in the soil or a fungal or other disease.
I would spray the plants with an aerated compost tea. In some areas you can buy such a product or you can make your own buy either buying a none sterilzed compost or making your own and adding this to a barrel of water and vigourously stirring several times a day.
