Leaf Curl Up Diagnosis and Cure

[whoose]

Noticed this upward leaf curl yesterday. I use tomato tone last week but nothing else special. Plants are in my Green House in 25 gallon containers. Any help understanding what this is and how to mitigate it are helpful. Different types of toms are differentially affected, these are the worst, other nothing.

I would say herbicide .
You might want also check the leaves closely w/ magnifying glass for pests.

Since your plants are in a greenhouse I doubt it's herbicide damage. More than likely it's physiological leaf roll. High temperatures, too much nitrogen, too much moisture can all cause it.

My greenhouse is experiencing the exact same leaf curl on tomatoes, peppers and potatoes.

yes, but herbicide damage can be caused by the medium that has trace of herbicide in it.
But what I said was just my opinion. I could be wrong.
