I put some of my dino kale from seed (1 month old, now) in the ground and one of them looks almost like something that has been sitting in the sun too long so it fades in color. The leaf is still wholly in tact and feels like the other leaves of the other kale, so it doesn't seem like it's dry or underwatered, and there are no holes like it was a pest. I guess it's kind of hard to explain. Any thoughts of why this may be?
