Unknown Auto Kush

When I received my Sweet Seeds and Bomb Seeds from True North Seed Bank they included two auto Kush seeds. I have no idea where they have came from. I decided to do a test, side by side grow between soil and coco. The seeds are the same size and sprouted at the exact same time. The seeds are now a week old and are the same height. When it's nice outside I move the plants on the deck to soak up the sunlight instead of LEDs. I took these photos 6 days ago. PS the coco is already looking bigger 🤪.
