Some varieties like Cherokee Purple do that sort of thing for me. Variety??? Is the leaf turgid or flaccid? Could also have to do with the tendency of plants to curl around supports and in this case they seem to be just on strings flailing a bit. It doesn't look bad necessarily if it is has turgor pressure holding it stiff and juicy. Let's see what others say...

Thanks PupillaCharities. I got some really good info from the Tomato diseases and pests forum, saying that it is a problem of overwatering and ethylene. I will let them dry out and air out and hope for the best.

Hi Peggy, for a tomato in my garden, that is not overwatering and *could* look good. If I over-water the curling is on the leaflets more than the leaves and it is the opposite direction concave upward, of your, and longitudinally along the principal vein in the leaflet. But, hey, different environments certainly can give different response. Different varieties have different leaf shapes. It would be good to say what variety to compare growing experiences with that particular variety. I think in this forum everyone has just about grown everything there is LOL & JMO

That is interesting PC. I noticed these first and most severely on cherry tomato called Sweet Treats. Now a few of the others are doing it too.

Yes, some tomatoes are much more affected than others, but I have not grown Sweet Treats, though I know many here have found it very prolific. It is quite likely that a heavy hand on the water as you said could have contributed to this. But some varieties naturally are like this all the time, for example Anna Russian is considered wispy and drives people nuts.

I would think if the plants continue to look nice and healthy you are probably ok and just take care to cut back on the water if you feel it is over-watered. Perhaps between the heat and water they just got a spurt of growth. That is probably what you were telling me by mentioning ethylene. A spurt of growth under ideal vegetative warm conditions could accelerate that.

As long as the plants actually look like their leaves are maintaining the turgor pressure and and have good color and flesh I would not get worried. Probably disappear for the most part shortly with your attention and TLC. JMOGood Luck!

Thanks PC. I grow Sweet Treats both because they are prolific and because the grandkids and neighborhood kids love to just eat them right off of the vine...

Hi Peggy - have they straightened up yet? How long have they been in the GH? I think it may be either lack of water or heat. I would give them more water even if you watered them yesterday. Mine will always look like that when I transplant them and then if they need water or the GH gets to hot. Is it just this variety or all the tomato plants in the GH? I am in on this thread a little late but give us an update.

Hi everyone, and thanks for all of your help. My plants are looking better in the cool of the morning today (about 47 in the greenhouse this morning with no added heat). Here is a photo I took this morning. Yesterday afternoon, when the temperature was in the 80's all of the plants looked even better. The leaves that were curled under now are less curled, slightly limp, but not wilted. I feel that the problem is under control for now.

Hi again everyone, Just wanted to give you the update. The plants got over their difficulties, and all are doing just fine now. It really only lasted a few days. On another site, someone mentioned that it was a problem due to ethylene in the air, from the propane heating that I had been doing when the nights were cold. that might have been it, because as soon as I stopped heating, the problem went away.

They really don't need to be kept at 80, as long as they get plenty of light, even 60 is OK until summer hits. Mine droop like that in the summer afternoons when the inside of my (unheated) greenhouse hits 100 or more, but are fine after the sun goes down and it cools off.
