Can someone please help me here?
Can you identify these spots on these leaves?
They are on plants in the greenhouse.


These are the groud leaves.

It looks like that is powdery mildew. I think a lot of leaf-disease problems are caused (or further aggrevated) by getting the leaves wet. I am pretty sure you can get a fungicide to get rid of it. I'm sure someone more knowledgable will be along to help you out!!

Yep, it's powdery mildew.....

You can also use a baking soda in water, foliar spray..

It is quite common for that to happen at the end of the season, the hot temps, the moisture build ups' and it grows...

rose petal, you should check out the link provided on the watermelon splitting topic as it shows Powdery mildew on watermelon plants, which are similar to yours.

Yep that's what I've got, powdery mildew.

I'm going to try the baking soda deal, but I'm almost sure it's impossible to get rid of any more, there's way too much already.

I have one other concern, my zucchini, squash and grouds are on their way out, they've done they're growth time, but my tomatoes and peppers are close by will it do damage to them?

I sure do know what you mean. I am just getting my garden started this year. I grew some sweet corn and some cucumbers in one part of it while I worked in a lot of composted horse manure and other organics into the other part. My corn did really well and my cucumbers started out really well, then all of a sudden I got brown blotches on the leaves and the whole plant just up and died on me. I lost all of them eek
I recently planted twenty five broccoli plants, fifteen regular cabbage, fifteen red cabbage and twenty collard green plants. I only planted them a week ago before we got a lot of rain and they have already been attacked by something because there are small holes in the leaves. I just sprayed them and bought some Dipel dust to use so that I dont get those green worms all through them.

Small green holes can be "Cabbage Loopers"...

rosepetal,
i believe your problem is lack of air circulation.
which causes mildew.

Art, I had a fan going all summer in my greenhouse plus open windows all around. But we did have hot weather this summer and very little wind which is unusal for this part of the world.

Budman, I had those little green worms in my broccoli this year so I sprayed them with "ambush", it worked great, I could pick my broc after 7 days and no worms.
