Can the upward leaf curling be just something some varieties do?
I have the same thing happening with my Lynn's Mahogany Garnet (open pollinated cross between Black Russian and Green Zebra). I worried initially, but they've been growing and fruiting... these 2 and the 2 Sugar Plums were protected with Wall-o-waters, and they are the earliest, sturdiest and healthiest of all my 20+ tomato plants. As you can see, the Sugar Plums are flat-leaved while LMG are all curly (They're planted 24" apart). Their growing conditions are exactly the same. They're growing in last year's sheet mulched Sunflower/Corn House and the soil is heavy clay after about 12" depth and the area stays soggy for a couple of days after heavy rain, so they ARE getting a bit overwatered.

Hey, I'm glad I decided to post this, I noticed some streaking going on with the still green and small LMG fruits and was wondering if the curly leaves are finally getting to them. I forgot about the Green Zebra parentage.
I don't really think fertilizer is the issue here because what I did here was I left all the corn stalks and sunflower stalks piled in the beds over the winter, then this spring, piled some rough compost, grass clippings and weeds on top, then topped it off with bagged compost. The tomatoes were planted by plying apart a space between still undecomposed stalks. Only other nitrogen comes from root nodules of the clover planted in the center space of the "Sunflower House" as well as the clover growing on two sides on the outside. So a lot of tying up of nitrogen might be going on, but the way they're growing, these plants sure don't look like they're nitrogen deprived.
