Hey My Stoned Buddy👊 I have had a few do something similar to that before. One of em looked almost exactly like that but within a week or so it start to show up out of no where like it was hiding inside the stem like a turtle head in a shell lmao. the other one just didn't have a node never figured out why i think it was either my error or something ate the node. but you should let it grow and see what happen it could be the best plant out of the bunch You never know. You may want to get another one sprouted just to be safe if you have the room. Hopefully she grows big and strong💪
