Need help diagnosing leaf spots

[hot turkey]

Hello all, my first post. I'm new at this and was wondering if any of you could help me out. I put some new tomatoes in pots two weeks ago. They were doing great until two days ago. Got some weird spots. I found this site and found it very useful in picking out some heirloom seed. I hope to get them started soon.

I think you may have some mineral Deficiencies

Magnesium deficiency 255. Central intervenal chlorosis and green marginal bands.

Let's eliminate the obvious first. Were those plants hardened off? The reason I ask is because it looks like sunburn or windburn to me. If you used fresh commercial potting soil I doubt it is a mineral deficiency. Mineral deficiencies are fairly uncommon.

Is the new growth okay?

Good luck.

Have you sprayed anything on them recently? I had something similar happen when too much Neem and/or Serenade got hit by the sun.

Agree 100% with WVTomatoMan. Looks like wind or sun damage from plants that were not gradually introduced to sunlight and breezes.

I think sun or wind damage, too.

I was going to suggest sun or wind damage as well. I had a few seedlings I put outside do the same thing.

Thanks so much for the help, they were new plants from lowes. The new growth looks better. I did give it some Magnesium.

I did not spray them with anything, I did not know I needed to harden them. That's new to me. I had some of the same spots on squash also. They don't get too much sun. I will post more pictures to show you. I have started some heirloom seeds and can't wait to see them grow.

What type of potting soil did you use. Did you plant your squash in containers as well using the same potting soil. Ami

I'm using soil from my compost pile and yes I planted squash, peppers and egg plant in the containers. I have some heirloom tomatoes coming up now that I will also put in containers. I will buy some soil for them, my first time planting heirlooms. All the tomatoes I have now in pots are from Lowes.

Ok, When growing in containers it's better to use soiless potting mix versus your soil from the compost bin. Disease is the number one problem when using soil in containers and two it will turn to clay after awhile unless heavily amended to keep it from packing. Almost all the container, "Earth Box", "Tainer" growers use the soiless potting mix with amendments to grow their crops. Check out the "Container Forum" here at TVille for more info. Ami

That looks like 4 tomato plants in a 10-15 gallon pot.

Thanks Ami, I will read up.
