I posted this smae message to the Garden Clinic forum- I hope it is not a problem to cross post...

I have tomatoes with leaf curl, and I've been reading lots of other posts but no combination of symptoms match mine. My plants are dark green, a few have underleaf purple (P deficiency which prompts me to give them more food). But the leaf curl is weird. It resembles 2,4-d damage in that it came on suddenly and affected several individuals of various varieties in my greenhouse all at once. I don't use 2,4-d and hadn't used any herbicides near the gh, but the gh is near a golf course so drift seems reasonable. However the plants don't seem to be growing out of the curl. They are blooming. I'm going to post a photo. Thanks in advance for your suggestions.
