Looks like the nutrition was originally too strong in soil based on dark green, and deformities.
You may also have a watering issue. I would add more course perlite when you transplant it In next substrate.
I'm having the exact issue. Leaves look deformed and wilted. I think I'm overwatering. Using coco, perlite and worm castings. I'm going to let them dry out a bit more before the next water and see if it helps.
