Default Tomatoes with curling leaves

Terry Coombs said:


I noticed yesterday that some of my tomato plants have something
unusual going on . The lower leaves on a couple of my plants have turned
a darker green and started curling up toward the top side . They feel
strange to the touch too , kinda "leathery" for lack of a better word .
Anybody got any ideas what I might have going on here ? Plants are in
"virgin" soil , used to be oak forest . Ground was broken for the first time
this spring , plants were put in holes with a 50/50 mix of dirt and
manure/compost , a tbsp of epsom salts in the bottom of each hole . 3
weeks after planting about 3 wks ago now I applied a light feeding of
13/13/13 .
THis problem has just shown up in the last few days and I'd like to nip it
asap . They've all but one got tomatoes on them .


Most likely tomato leaf roll, caused by a specific gene ('wilty' gene) in
response to stress (anything from heavy fruit load to high heat or excessive
nitrogen).

Virus that cause leaf roll usually also cause the leaves to become lighter,
rather than darker green.

Herbicide damage is most likely to affect new growth and cause more
extreme
distortions.
