I tried most of your links but couldn't get any of them to work...

Hi, no problem with the pics. I'd take those problem leaves off right away. They're definitely not going to heal and aren't helping the plant in any way. Bottom leaves invariably pick up something if touching the soil so a plastic mulch helps to keep bacteria away. Aphids can cause some strange leaf curling and they like plants that are fed too much nitrogen. Other than that the plants look fine.

Leaves curl when they are stressed.

The pic from June 15th closeup looks like physical damage and not necessarily some kind of bug/pest.

If the shoots are outgrowing the roots, the leaves will curl until the root mass catche up to handle that much leaf surface area.

Wait and see if it doesnt grow out of this. You could be looking at some disease problem or root damage but if so there isnt a whole lot (other than avoiding ammonia based nitrogen) for those.

Although we are not experts, how much are you watering and what type of soil, and zone? Seems that your soil is rather light (as in no organic matter) and lack of water containg capacity.

Hey what zone are you in? The close up pic "June 15 Leaf closeup" looks like sun scald to me, I have leaves do that on hot days here. Maybe the hot sun beating off the the red brick is creating high temps burning the leaf and creating leaf curl once they are in the shade. I'm not an expert, just a guess.
If so you should hold back on the pruning to create some leaf shade.

How are you irrigating? One of the simple solutions is to water consistently. Burst irrigation over 4 cycles prior to sundown works quite well and keeps the plant in balance.

Your curled leaves are simply the result of excessive water transpiration.

If you can, move to drip irrigation, either spray stakes or Toro AG's drip micro tubing and use cyclical timing, at least 4 times a day with the highest duration prior to sundown. Consistency trains the plants.

Another thing I would do is remove what looks like grass and those weeds against wall. Then add a mulch to help with moisture retention. Good luck to you.

Unfortunately I experienced the same problem with several of my heirloom tomato plants. I found I was over-watering. Once I cut back on the water most rejuvinated. However two plants remained curled (and even got worse - it spread from just a few leaves to the entire plant). One plant looked so unhealthy that I immediately pulled it up to avoid potentially spreading a disease to other plants. The other I left alone. For several, weeks while my other plants grew tall and thrived, this "speckled peach" variety's growth was stunted and eventually turned yellow. There was no hope, I had to pull that plant up as well.

I did alot of research and never found a disease that matched my plants' symptoms. Hopefully your problem is just from over watering (or what the books call "cold and wet weather conditions"). But if the leaf curl continues to spread through out the plant there is not much hope.

I hope this info helps

Reside in TN/Zone6
I irrigate weekly placing the hose at the stem of each plant, turn the water on for exactly 20min at about 1/4-1/5 pressure.

Soil= MG Potting and MG Garden soil,.05/.05/.05 Cow manure and about 6tbsp of Osmocote slow release into the dirt of the bed...... all mixed real well.

As for the grass on top, that was exactly 1 mth ago today and is gone. The person who posted my pics above missed the actual May 18th photo and posted 2x pics for June 3rd ;)

The plant along the back wall right is Wild Strawberries which the birds eat the fruit and help squelch the bug population.. I now have tomatoes starting on the plant on the right.

To Mulch or not, I don't think I need any because the bed only gets 4-5 hours of sun a day. It gets fairly hot but I don't think we've hit 90's yet.

The plant look fine for the most part except for the bottom leaves. I removed the blackened ones.

Burpee Supersteaks side by side. One's 5', the other is 6'.Both are just getting some tomatoes :) I made the pics supersize so you could see better. Some more info is in the post above.
