Dodge and Angelblossom:
Thank you for your responses.
This is the first time I've ever tried to grow anything - I just sort of had an impulse this year and gave it a try. I live in a city in a third floor apartment. Essentially there is no "outside." I do put the plants out on the fire escape where they get about 4 hrs of natural light, before bringing them in and using grow lights. Perhaps being out side is where they were exposed. It has rained pretty much all summer (for a month straight at one point) and I read that that contributes to the blight. Having identified the issue I've been reading up about it, and apparently this year blight has been a big issue. The cucumber has developed the blight/powdery mildew over the last two weeks. The green bean plant has been dying for the last month. Other gardening forms believe the green bean plant has mites.
From what I have read so far, it looks like a Chlorothalonil fungacide for the powdery mildew and for the mites maybe a Rotenone insecticide. The plants are probably too far gone for organic solutions. Any other suggestions? I'm not sure they will survive long enough for me to get anything though.
I also have a strawberry plant that is doing well and producing, and a blueberry plant that is doing well but is still two years away from producing, and a tomato plant that is extremely robust, but hasn't produced a single tomato.
