I thought i just posted this, but cannot find it so i will try again:

I have several problems..

1.lowerleaves yellowing and have tiny pin size brown spots.

2.some leaves have larger brown areas with large yellow surrounding it.

3.leaves are turning brown on the tips.

I have pulled many leaves, this started with a few plants now has hit all of them. the potato leaf ones too...

I have pulled up the worst. Still have about 90 plants..

The top growth looks very green.

only a few have any buds.

Q. If these produce any tomatoes..can I save the seeds? or Will the problems be passed onto the seeds?

I visited some of my tomato plants while visiting a friend..who lives farther south and has bright sun and no shade. The plants look great there, strong, healthy, HUGE, lots of buds..so now I know it was not to do with how I started them in my basement..Something is in my garden..

What can I do so that this won't happen again next year??

Sad but not wanting to give up...I even gave in a used a copper based spray on the leaves...Martha/zucchini ;-(
