A friend I sent this pic to said mites. I see a few small green things on the underside of some leaves. She recommended Spinosad. Any other suggestions, please let me know.

Thank you digdirt2! Your advice has been invaluable! I did see a few bugs on some leaves, but nothing that seemed like an epidemic, but I have no idea how many mites it would take to start damage if it were from them.

I first noticed this last Friday and they seemed to be better the next afternoon. Then I noticed it again today. Some varieties seem more affected than others. Purple Russian seemed to be the most affected. We have had a very warm spring and I've had difficulty trying to find the right level of watering. Then it kills me since some seem to dry out faster than others, and trying to spot water that many seems like an effort in futility with this may starts! This is my first year growing starts for sale (I have a booth at a local farmers market) and I love what I'm doing, but I do have some perfectionist tendencies and can't stand seeing any plants having issues.

It does seem to affect the lower older leaves first, and I don't see any discoloration. So perhaps what the article stated "The disorder is also attributed in some areas to
excess soil moisture coupled with prolonged
high air temperatures." is my issue. Slightly too much water, and high air temps. "Rolled leaves become rough
and leathery but are otherwise normal in size
and appearance. There is no discoloration of leaf
veins associated with this condition." The leaves do feel rough and leathery, and all else seems to match what this article says.

Again, many thanks!

No problem. And believe it or not it does no permanent damage to the plant, merely a symptom to be monitored and the cause eliminated when possible. It like the physical indigestion we get sometimes when eating spicy foods, we ignore it, take a TUMS, and keep on eating. :)

Good advice and conclusion.

Also some varieties show leaf rolling for no serious reasons. Today I just noticed one of my Willamette had lower leaves partially rolled, while other varieties in the same bed are fine. They were all grown from seed and planted at the same time. Two years ago I had a Black Kirim. It had rolled leaves most of the season. So , Some people suggested it was stressed because of puning. Some said it was because of too much water. How come it did not happen with the other varieties ?
if I cannot see any bugs (aphids, mites) I would not worry about it. JMO

It seemed to be predominately Purple Russian, with a few showing it in other varieties. I took a pretty good look at other plants that had leaves rolling, and aside from a very few aphids I didn't see anything to be concerned about. For the most part, the other varieties showing it seems similar physiologically to the Purple Russian, tall and thin leaves, not the bushy varieties.
