What is going on here?

I've checked the Plant Physiology FAQ and a number of other nutrient deficiency papers and can't find anything quite like this.  It has the appearance of a Copper deficiency but others as well, such a spotty necrosis and veinal necrosis at the stem.
 
These are Carolina Reapers, two young leaves the rest of the leaves look fine as do all the leaves of the other plants..I'm just wondering if I should be concerned, as it is my largest start so far.
 
Also the affected leaves are highly curled.  There is one unpicture leaf that is almost entirely curled into itself, it also show the veinal necrosis and flecks.

How old/big are these plants? If they are large enough you can apply a foliar minor element spray. I use this.

CHELATED GENERAL PURPOSE MINOR ELEMENT SPRAY • Can be used on all plants including lawns • Contains 6 important nutrients including iron • Prevents & corrects deficiencies that cause yellowing CONTAINS: Iron 2.75%, Manganese 1.00%, Zinc 0.50%, Magnesium 0.50%, Copper 0.25%, and Sulfur 3.8%. USE ON: Flowers, shrubs, trees, vegetables and lawns CONTROLS: Minor element deficiencies, yellowing of foliage, etc. NOTE: Deficiency symptoms can be caused by improper soil pH. RATE: Foliar: 1 tbs. per gallon of water drench: 1 oz. per 100 sq. ft. Lawns: 1 pt. per 1,000 sq. ft. APPLICATION: Mix with water and apply as a drenching spray.

Some varieties seem prone to leaf curl. Datil is one that requires regular spraying here to correct this.
