Disease, sunscald or ?

[Farmette]

Gardens are planted. Tomatoes are doing well in one location. Another garden in another location has just been developed and made into raised beds. The new beds have been made I think completely of mushroom compost. I took two pictures this am to show some of the damage. Here is a copy of my email to another garden member as we are trying to figure out what this is. The tomatoes, eggplant and peppers were planted in the new raised beds last Sunday; today is Friday. They started showing signs on Tuesday or Wednesday.:

It appears as if eggplant and peppers are affected as well as tomatoes. There might be more than one thing going on. From what I have read, it is unlikely that worm castings are the problem. I noticed that on some of the plants, the stem has turned a very pale green. Those toms that are affected often have lower leaf damage with some having top damage. Peppers seem to be affected mostly on the top leaves. I am wondering if we should trim the bottom leaves off the toms and see how they do in the next 3 days. Those with severe damage will need to be replaced. I may have identical replacements for some. I am wondering if we mixed the mushroom compost with preexisting soil. If we didn't, could that be the cause? Have we ever planted tomatoes directly into mushroom compost. Is it possible this batch was particularly strong?

So, does anyone have any guesses as to what this might be. I think it is likely that the same thing is affecting tomatoes, peppers and eggplant and possible that there is more than one cause. All plants were hardened off and healthy when planted into the raised beds on Sunday. A little leggy, but healthy looking. Weather was originally cool, then quite windy followed by temps in 60s and 70s. I think there were two nights in the 40s.

Any thoughts would be appreciated.

It sure looks like sun-scald. The new growth looks good.

Definitely sun scald. I have seen it many times when I was gardening in El Paso

Yep, I agree, it looks like sun scald. They will grow out of it. The new center foliage likes great.

Could be sunscald, as mentioned, but I would also suspect salt damage, especially if you planted directly into the mushroom compost. Maybe try starting some bean seeds in the compost and see how they look.

Good luck.
