Should I grow out this mutated week 2-3 Auto Ultimate?

You guys are right, there's nothing wrong. I just looked at all those new shoots and got confused I guess. Thanks for your answers! 👍

seems like a regular ass plant to me

no parece ninguna mutación... pero creo que se está espigando un poco, acerca un poco mas las luces, rellena con un poco de tierra el tallo. saludos

Looks quite normal to me tbh...😸

I would keep growing it. Having all those shoots or nodes are a good thing as the plant will be nice and bushy with lots of tops. I personally found autos flowers don't like training as they grow so fast and the best mindset to have with them is to just prevent as much shock. I wouldn't say this is a mutation and it is what I look for in my plants. Lots of shoots or nodes. I currently have a Guava dog I started from seed indoors and put outdoors to flower. It looked similar to yours when I put it outside and without any training, it is now filling up a 3X5 greenhouse and the plant is over 6 ft! Good luck!
