I know the others already said it. But there is definitely no need to worry. She will grow new growth for another week and start showing pistils in the next couple days. My autos were well into 30 days before any hairs showed but they are about 35days from harvest now and they are just beautiful . This was also my first time.e with autos so I was unsure of what to expect but they certainly won't let you down.
I don't know what the breeder says about the strain, but if the breeder says 4 weeks of veg, you won't see signs until week 5, possibly week 6 depending on the genes.
