Can you show us a picture of your plant before you destroy it?

I will certainly post a pic - but need to take it first so give me a day or two.

It's been in a pot on my patio right next to 11 of my other potted peppers and not far from my garden with in ground peppers for a few months so far so keeping it for several more days is not giving that much extra relative contamination exposure risk.

(It's a Bishops Crown, not 'Cap', doh)

Moat mosaic virus I have seen discolors the plants severely - like rot. There are browns, yellows etc. thats why they call it mosaiac. What you are describing sounds more like a nutrient/micronutrient deficiency or lockout. Show a pic.

That would be interesting (but not impossible) if it is a nutrient issue as I have 2 plants all purchased at same place (CCN) and planted at exact same time in same potting soil with exact same fertilizing (fish, seaweed + some epson). The other 11 are all growing vigorously (as it this one) but with smooth/normal leaves.

There is a chance it is not a Bishops Crown. I may have mis-remembered which one it was. Are there pepper varieties with crinkled leaves?

Like I said a picture will come.

I have the same symptoms on several of my plants, which are growing rapidly and flowering. Yikes! If this is a virus, is there any treatment? If it isn't, how to determine what nutritional deficiency is present?

Are you plants getting extreme heat (105-110F)? I have a theory this may cause the crinkling. The plants wilt severely in the heat every day leading to structural damage in the leaves.

While no other of my potted plants do this I have some in ground ones with bent and twisted leaf veins. I noted last year as the temps cooled down the new leaves stayed normal.

crinkled leaves says to me a pH problem or possible insect infestation. spider mites perhaps?

Crinkling or deformity of leaves will not be caused by heat, mosaiac disease. It is almost 100% caused by: transplanting into a "hot" or super fertilized mix, genetics, a ph problem which causes "lockout" of certain nutrients, and sometimes by an insect infestation. I would guess that it is nutrient or ph caused at this time. Toss some dolomitic pelletized lime on top of the containers and see if that helps. BTW, What color are the leaves? Any brittling around the edges? Are the veins lighter than the rest of the leaf? Lots of things come into play here. Most times, this straightens out. TiMo

The crinkling is equal on new and old leaves and uniform and no brittling. Color is uniform. No insects even under close inspection.
I've had nutrient issues before (here is it iron & zinc due to ph) Ca in soil and water is very high here. Correction is with acidifier & chelated Zn/Fe, or S for longer term- quick fix with folar spray. (none of anything I just mentioned has been done on potted plants)
I don't remember the name of the potting soil I used, but I didn't use fish emulsion and small bit of seaweed extract (bot cases diluted to ~30% of recommended) until 4wk after. No other fertilizer.
