Looks normal? If not Powdery mildew then is it something I should be concerned with?

I don't know that I've ever had PM on my tomato plants, but I've had it on other plants and this looks nothing like it.

Possibly damage caused by thrips?

[Stvrob]

what part should we be looking at? They look pretty healthy to me.

That's what I think it is.
Stvrob we are talking about those white spots on the leaves that look chewed out by a very small insect.

holyhotpeppers,
I don't believe that it's powdery mildew in the picture. It would be more widespread and look different from what you have pictured. As Marsha said earlier, it looks more like chew marks left by an insect. The damage at this point looks to be minimal. If you have a good magnifying glass or a loupe, you should use it to examine the leaves a little closer (check for thrips or mites). If it's powdery mildew, you'll see it spread within days. You're more likely to see powdery mildew on cucumbers or squash. I don't think I've ever had powdery mildew on my tomato plants. I would keep an eye on it for a day or two, and if it doesn't get any worse, no harm, no foul. Good luck with your plants and I think you'll be ok. Let us know how you make out.

Thanks so much! It would make sense as to the chew marks. Mites are always a slight issue where I am at.

I treated with Bonide fruit and nut orchard spray so if they where thinking my tomatoes where an all you can eat buffet well.... That restaurant is no closed

Some of my seedlings have similar pale patches with little teeny tiny black dots in a few of the patches

No widespread brown patches or anything. I thought at first it was sunburn with a bit of dirt kicked up from the rainstorms we've had this week, but now I'm nervous.

Should I do something? Wait it out? Throw them out and start over? It's getting to be time to start my fall crop of seedlings anyway, but I'd sure like to save the dwarfs at least!

Tl- a picture would be helpful, and a closeup would be really helpful.

Hopefully this works!

The first picture looks like whitefly colonies, but I don't see any whiteflies. They have lot of them in Texas though. The lower picture looks like mildew. Do you have any very small white flies on the undersides? I think I am leaning toward mildew. Try 2 teaspoons of liquid copper fungicide mixed into a gallon of water, and add 1/2 teaspoon of dish soap to act as a spreader. Copper fungicide works well on mildew, and it is considered organic. I get my concentrate from Home Depot. If it is whiteflies, Neem oil spray also mixed with a little soap works well.
In either case, you may know this already, but don't make the newbie mistake we all did of spraying during high sun. Rather spray only early AM or late afternoon. Spray can fry the leaves in the sun. Also, don't mix the 2, individual spray only please.

Thank you, I will go to Home Depot as soon as possible. I appreciate the explicit instructions, too, I would have used both at once!

Can I alternate them?

I didn't see any flies, but I did spot a large spider. And it's been cool and went here.

Yes alternating them is the way you should do it. But wait a day between.
Another thing you can do if you do get whiteflies is yellow sticky traps.
Here's a link:http://www.amazon.com/s/ref=nb_sb_no...w+sticky+traps
I get 2 packs to get the free shipping because they don't go bad. I put them out about every 4 feet, they twist tie onto my trellising. Whiteflies are strongly attracted to the yellow color, so are leaf miner flies, and since I got them, I didn't have to neem again.
Personally, I will never garden without them again. They last the whole season, and are less than a dollar each.
Right now though, I think it's fungus.
