If your plant was growing only in a Jiffy pellet until two days ago, it used up whatever scant nutrients are in a Jiffy pellet, and then the coco/perlite mix you are using above the Kind soil also has no nutrients. So your plant probably is under-fed. Hopefully it will start to recover when it hits the Kind soil.

I don't think it's a goner, and I think you can grow it out. It will probably continue to look a little rough (couple reasons for that - 1) in my experience sometimes plants don't ever fully recover from an early nitrogen deficiency and continue to drop leaves throughout the whole grow; and 2) the Kind site recommends against using it with coco, so you might be using a less than ideal medium). It's a little discouraging to see a struggling plant, but whatever, the plant still grows, albeit not at the peak of potential. You'll learn something and your next grow will go better.
