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 .

Have you checked the soil pH? Tomatoes like 6.0-6.8, slightly acidic. Since you're planting in a former oak forest, the soil might be too acidic for them.
