This year is my second "proper" chilli grow; I did reasonably OK last year. I'm growing 12 chinense varieties from seed and all the rest of the seedlings look "normal" except these two. The first pair of true leaves look normal but the second pair looks deformed - narrow and twisted. Since I took the photos, the third pair of true leaves is starting to form and also looks deformed.
They are Brazilian Ghost. Grown in the same compost in the same conditions as the other plants which look absolutely normal. I can't see any pests. Could it be a seed-borne disease (e.g. virus) in which case I need to get rid of these plants before others get infected, or is it normal for them to have narrow twisted leaves?
I'd appreciate any advice / suggestions.
P.S. They are in Biobizz Light Mix, watered with luke warm tap water (soft) which has previously always been OK for my chillies. No fertiliser other than what is already in the compost.
