MrStinkyanswered grow question 3 years ago Let her grow mate - I've got a mutant and a 'normal looker' in my current RQS NLA diary
It seems to be attempting to outgrow the regular looker, I was tempted to pull it and plant another and like you I asked the GD Family and the advice was to try letting her grow.
I'd say give her another 3 weeks and if she looks like shit and wo 't grow get a Fastbuds seed or two to make up for the lost time 😉
You never know, she might go beast mode and surprise you.
