Bacterial spot? You might want to send this pic to your county extension for better-informed advice. Here is a link that might be useful: UF/IFAS Extension

I'm not getting enough clarity off of those photos to really pin it down... but you mentioned that the spots were small, and they look quite dark. Is it progressing just a couple of leaves at a time, rather than by leaps and bounds? Fungal spots tend to show up so fast it's breathtaking, especially in wet weather. If it's going slowly enough that you can note which leaves get it and when, that suggests a bacterial disease. If the spots are also pretty consistently small -- 1/8" or less -- I'd try treating for bacterial speck or spot, and see what happens. Pick off the worst leaves, as they won't get any better, and throw them in the garbage can. Then pick up some fixed copper spray from the hardware store or nursery, and spray them as directed (or as close as you can -- I understand you guys are building arks out there). If and when the rain settles down, you should be able to get a handle on it pretty well. I'd suggest mulching just on principle, but I'm guessing plastic tarps might be more useful right now. Soil splashing up onto the leaves just makes matters worse; once the bacteria or fungus has a foothold in the lower leaves, though, it spreads upward by water splashing on those leaves. --Alison

Hi! I'm so sorry, Jean001a, I haven't replied sooner but i have been away (got the neighbor to look after the garden :). Thank you for you response. I had used miracle grow organic all purpose plant food NPK: 7-6-7 when i transplanted the plants to their grow bags. (i don't know what it is made up of though). Luckily it seems as though they have recovered. the leaves are mostly green. However, i think that the fertilizer had too much nitrogen as the plants are now 1m tall and are only just starting to set their first trusses of flowers.

Any ideas what is going on here? Green beans: Also this white stuff and green spikey stuff on cucumber?
