Would really appreciate help...

Difficult to determine what is happening.

Suggest you contact your count's Extension Service office for help. They'll know locally important problems and, if the office is within a
reasonable distance, you can take in samples for first-hand look-see.

Looks like powdery mildew to me. There are a number of fungicides that may help, depending on how organic you want to be. Something like neem and/or potassium bicarb would be a first choice for organic gardeners.

Thank you!

It's still also a good idea to consult with your local extension, as Jean suggested, if you live in the US in a state that has such programs. There is only so much diagnosis people can do for you over the Internet.

Me again! I didn't have a chance to get to an extension office but it seems the problem has moved fairly quickly as I'm getting dark spots on new growth... this wasn't happening earlier:

Its on all the plants... including peppers

Something clearly eating the leaves.. and one of the bell peppers just as it ripened..

If this should be posted elsewhere please let me know. I don't know if:

1) The tomato plant and pepper plant damage is related?

2) Is my garden doomed? Do I need to start over? How do I make sure this doesn't happen again?

Thank you!

Can anyone help?

Thanks!

This may be a separate problem from the previous one or a coexisting one. Hard to diagnose from those pics. My guess from the recent batch of photos would be bacterial spot, which affects both tomatoes and peppers. If it is, you will probably start seeing raised spots on fruits. Not sure about the bell pepper damage. It could be from a pest or it could be a scar from environmental damage of some kind.

It's possible you have multiple problems, which can make it hard to figure out what's going on, so I suggest you consult your local extension office for a definitive diagnosis.

Does that mean the fruit is no longer edible if it is bacterial spot? Thanks for your help!

It won't hurt you to eat affected. It just looks ugly. And it's not safe for canning.

But if it's bacterial spot, there will be reduced fruit yield as the disease often attacks peduncles and flowers in addition to foliage.

To be clear, the fruit shown in your last picture is not showing bacterial spot lesions. It's showing some kind of physical damage, probably environmental or pest damage.

Once again, though, contact your local extension to get an actual diagnosis. These sorts of things can be iffy to diagnose over the Internet unless the presentation is unmistakeable, especially if you have more than one issue going on.
