Okay, this is a new one on me and it's probably my fault for letting a friend "save me a few bucks" and letting him give me his "personal mix potting soil" rather than snagging a bag for my seedlings I was transplanting. It looks to be a potting mix, btw. There is no significant organic moss waste or anything else in the soil mix that would hold water in the soil for long periods of time.

NONETHELESS...

2 of my pepper starts out of 8 are showing some stress I haven't seen before so I hope someone here knows what it is...

The leaves first showed a sign of mild chlorosis on older growth followed by the leaves "rolling" down/under...but not rolling as much as "corkscrewing". A few lower leaves have actual burning in between the veins, but that is only present (though pronounced) on 1 leaf on each plant (older leaf). The other leaves with the corkscrewing are still healthy looking.

The chlorosis isn't showing up on newer leaves. The rolling is, though it's not as bad. I don't know yet if it will get worse as they age.

Plant growth is normal and everything but the leaves look healthy aside from this. The plant is producing new growth on par with its peers.

I'm thinking it's a nutrient imbalance (actually a nutrient burn), but I'm not sure. I've never seen the "corkscrewing" of leaves like this on a pepper. I don't know if a nutrient imbalance can cause the corkscrewing, though. That seems to be a virus-like activity, but I have no idea what virus I could pick up from clean soil (yes, the soil was sterile before his "mix" and the seeds I've never had a problem with).
