Hi mate,
Shes looking huge! As you can see the pistils are still very white. I'd give her a few more weeks before you make a decision on chopping.
I've got 2 blue dreams from fastbuds and one has been super frosty for ages now and the other is only just starting. Dont stress, let her mature a little longer, she looks like shes going to be amazing by the end.
Hope this helps 🙂
