The blossoms are normal. Your in ground plants will likely recover from Mother Nature's abuse.

As for the seedlings still in cups, I haven't a clue what is wrong with them. I check the diagnostic pictures at a couple of sites Tomato Problem Solver (Photos for Diagnostics) and Cornell's Vegetable MD Online and don't really see anything that looks just like your plants. Could they have been under watered? Had their leaves spotted with water while in the cold frame so that it burned them? Have you done a foliar feeding that might have burned the leaves?

If you suspect disease, you might want to toss them just to be safe. Or if you have an isolated place to plant one or two, you might try it. Bear in mind if they are root bound, they may not do as well as your new seedlings. The new ones are likely to pass the others up if you don't get hailed out again.

I wish I had better info for you.

I'll see what I can sort out, ok? First,

So now I am trying to figure out if my plants are stressed or not. I discovered today they have blooms on almost all of them (several are megablooms). These plants are 6 weeks old, at least 18-24" tall and have decent growth since the hail storms. Are these blossoms normal for these plants or does it indicate stress? What should I do?

Yeah as Betsy said the blooms are mostly normal and megablooms (fused blossoms) are common in the spring and caused by the fluctuating temps. They only pose a problem if they are on the very tip of the stem and if so just snip them off.

However the plants do show indications of lots of stress and nutrient deficiencies. What if anything have you fed them since planting? "topsoil, leaf compost, bark chips and turkey compost" alone isn't going to cut it for nutrients. And I hope the turkey litter was well composted first?

Personally I would lay them over on the soil - looks like you have room - and bury all that naked stem under several inches of soil. Just leave the tops above grounds and move your cages over. Water them in well. Give then a week then feed them well.

The plants in the cups look not worth saving. Leaf color is poor and they look like they have Alternaria. But that could only be if they have been outside or the fungus was brought inside on your hands or such. Is that possible? If so, pitch them and disinfect everything well so that hopefully the fungus won't spread.

Sorry for all your problems.

Thank you both for your responses. This is the first year I have ever tried to start from seed so I'm still learning alot.

Betsy- they have dried out a couple times due to the unusually hot weather we are experiencing but otherwise stay relatively moist. I don't think they got sunburned because I try not to wet them when I water them and I water them later in the day (bad I know, I'm working on fixing that). I have not done any foliar feeding as they were planted in Miracle Gro and/or Sta-green potting mix, both which have fertilizers.

Dave- I was worried it was a disease which is why I was hesitant to put them in the garden. These plants have all looked pitiful since I transplanted them (not sure why). They never grew tall or bushy like the others that were seeded and transplanted at the same time. Thus I kept putting off putting them in the garden as they never looked 100% healthy. They have had the yellow discoloration for awhile, probably since a few days after they were transplanted. Is this the same as early blight? The cold-frame is outside and made out of wood with a glass door. I open the door almost every day and keep it open at night when the temps stay above 50. I will more than likely throw them out as it is not worth risking. I have a long growing season, so I can try other options (plus 60+ seedlings that are ready to be up-potted that are a little leggy but appear healthy otherwise.)
As for the in ground plants- they are stressed most likely because of this insane weather here. I thought our temperatures were safe to plant and since then we've had numerous nights in the 40's and upper 30's which I know they do not like. I think the soil is a little cool because I am noticing they are starting to turn purple again. Our daytime temps though usually stay in the 70's+. The turkey compost was well aged I believe as I bought it from a reputable source in my area and looking at it when I got it, it just looked like dirt and bark so I'm hoping it was. I have not fed them anything since planting as I am not even sure what the best thing to feed them would be. What do you suggest. As far as my plants in the garden, should I pull them up and just plan to replant with the new seedlings I have or should I keep trying to save them? Also, it's probably worth mentioning that I believe I have a MASSIVE infestation of clover mites all in and around my garden. The reason I believe they are clover mites is because they have dark bodies with red legs and move quickly and are on EVERYTHING, plants, soil, grass, blocks, etc.

Thank you for all of your help in my never ending new learning experience. :)

If they have been outside in a cold frame then they could easily have contracted Alternaria. It is a different disease from Early Blight and you can read all about it on any of the tomato disease websites. But no you do not want to use those plants. They will just spread the disease - the fungus is air borne. They need to be bagged and disposed of away from the garden.

As to fertilizer, that is your choice out of the 100's available, both organic and synthetic. Most do a hole prep including fertilizer before planting, some use liquids, and some side dress the plants with a granular. But either way you have to feed them something and do so regularly.

As far as my plants in the garden, should I pull them up and just plan to replant with the new seedlings I have or should I keep trying to save them?

Yes I realize it is stress from the weather but the damage has been done and they can't be left like they are in the pics. They will just collapse. So just as I answered above - Just trench them in - "lay them over on the soil and bury all that naked stem under several inches of soil. Just leave the tops above ground and move your cages over. Water them in well. Give then a week then feed them well."

If the weather cooperates and you feed them within 2 weeks you won't recognize them.

Thank you so much. I will work on getting the tomatoes planted tomorrow or Tuesday, although I was going to try that when I planted them initially and chickened out because I felt like I was going to break them lol.

Now my worst fear question... since it is alternaria and I had these plants in the cold frame with other tomatoes, peppers, and eggplants... will they all get it? Is there anything I can do to prevent further spread, especially since I planted out 2-3 plants in the garden that are now showing signs as well? I will pull up any with signs and dispose of the other ones right away.

As far as fertilizer also, should I worry about high nitrogen ferts now or just feed them anything at this point? I have 5-10-10 granules, 8-8-8 granules, liquid soluble miracle gro. I know high nitrogen is bad for them for the most part, but should I be concerned with that right now? I am sorry for all the questions but I think nothing is better than hearing from someone who has experienced this before :)
