Ye. She'll be a quick 1 for sure. Must have lots of Ruderails to be pushing that out so quick.
Perfectly fine. Id stay away from any nutrients for a while, tap water will be fine for a few days. Then day 4 or so start pushing a very light diet on her.
Idk what you got for growing but she is fine.
I've had my ganja runtz or 1 of them go like that. Can't remember.
Happy growing pal.
