Tomato leaves black edges

Please help!

On one of my tomato plants [maybe 2], the edges of the leaves are turning a dark brown or black and shriveling up [of course]. To clarify, not all of the leaves but several of them are showing this problem. There is damage to the leaves only - there is no damage to the stem.

Also in case this is important - I ran out of places to plant in the ground this year so these are in "really" big pots. Only the tomato plants in the pots are showing this problem. The ones planted in the ground look fine and healthy.

Any idea whats wrong?

Please find a pic attached.

Thanks in advance,
Chad

What kind of pots are they? It is possible that plant roots are getting too hot because the pots are getting too hot. Try slipping yours into another larger pot that will help keep the pot the plant is in cooler.

And therein lies the problem.

Growing in containers, especially in your hot area, is a challenge. You really need to sometimes water them a couple of times a day. Since you said BIG pots I assume that crowding is not a problem.

Even if you could shade them as several of my friends in NM do, might help. They use those shade cloths you can buy there locally.

SirZoltan, I have never seen necrotic edges like that in pictures of diseases, etc so I did not hazard a guess. Did you find out anything? Did it progress?

I have read that potassium def. can effect leaf margins but again I have not seen anything quite like that at reference sites.
