Can I tier this?

Hey everybody I have a northern light blue auto that's a little over 3 weeks and I started it in a 1 gallon pot with the intention of tiering it into a bigger pot. I haven't gotten around to it yet and Im not sure if its too late but I'd still like to so I can maximize my yield. Here are some pics of her

I would just transplant her into bigger pot,just make sure the root ball is moist so it doesn't fall apart when you move her.

Thanks namvet. Should I feed the soil that I'm transplanting into?
