More time under propagator?

Yes my friend to transplant her now will most likely cause her stress and when shes this big I wouldnt want to stress it at all My personal advice leave it in there until you can see some root growth at the bottom of the plant like a good root system so you know the shock wont kill her when you do decide to transplant :) though on the flipside this is an auto so I really would advise getting herr in her final pot as soon as you can so the ball is in your court I would personally wait one more week but thats just me she will always uptake the higher humidity and grow faster but as i said stressing an auto via transplanting is not recommended it can cause so much stress you have dramatic problems like she will flower instantly or just take ages lol though its your plant pal you do what you want im sure she will do you proud :)
