Seed-borne viruses afflict peppers, and they may also affect tomatoes.  The
advice for "cleaning" seed of viruses in peppers is to pre-soak seeds in a
10% solution of tri-sodium phosphate for two hours.  Weird, huh?
Tri-sodium phosphate is the TSP sold in paint stores to clean walls before
you paint.  Hope it's just a nutrient deficiency.  Margaret
