Yellow leaves, pronounced veins
 

I'm attaching photos of tomatoes in a garden plot. All tomatoes look like this; they were healthy green upon transplant. Another bed in an adjacent garden was transplanted into at the same time and I believe the soil amendments were the same. Tomatoes in the adjacent garden are normal size, healthy green. Those in the photo from the first garden are all very small weak looking plants with yellowing leaves and pronounced veins on many of the plants. I notice quite a few small round holes on lower leaves and would think these would be flea beetles. The question is, would the damage from these beetles cause the plants to turn yellow and become weak.? Or is it possible they are suffering nutritional deficiency and those in the other bed are not? Thanks for your thoughts.

I will try to share photos in a bit.

Hopefully, here are the photos.

Looks like a nutritional issue. Have you tried giving them a little nitrogen?

Thanks, not yet. I can do that. The beds were amended with a mushroom compost mix this spring, just like the bed in the other garden, where all 8 plants are green and healthy.

They need some nitrogen and you can also add 1 tablespoon of Epsom Salts to 1 gallon of water which will also help the green them up quickly. You might also want to check the PH of your soil. Mushroom compost is usually quite alkaline.

Thanks, Miss S, I didn't know that..I had planned on checking pH, etc.

I usually see yellow leaves like that when the plants need nitrogen.

They're just planted. Something is not going right (nitrogen) and my guess is the problem is the roots that don't absorb. Usually in such cases one either waits or a very dilute foliar spray. Adding stuff to the soil may make things worse.
