Is This Auto Stunted?

Hello I think she's not looking bad given the low night temps. If you could raise that slightly to where its above 61 that would be a good change. Or you could try some lst to open up some of the new growth sites. Me personally I've usually had some smaller F.B plants...and they really only showed their boost in growth around when flowering begins. Hopefully this plant will do the same and show some nice vertical growth over the next 3 weeks. Make the environment as comfortable as possible and she should pull through a bit stronger. *you could also try raising your nutrients to 1 ml/l and see if that helps too. Although making adjustments when the leaves are so beautiful and green might not be necessary. Happy growing. ✌️
