Hi figlegacy,
The tree is yours and so is the final choice.
If she was mine, I would let her grow and cut end of this year or beginning next year.
I would then have a cutting + a tree , or an airlayer + 1 tree .
Which strain is that? Was the cutting pricey ? Hard to find ?
As most of that tree is softy green growth, I wouldn't cut now. I prefer to cut in hardened wood.
If you pinch, IMO, the tree will be too high . From the tip to the dirt , at the present size, I would cut that tree by the middle, to have low branching ... But that's me .
You could as well set an airlayer right now at the middle of the height of the tree, and separate the airlayer in a month or two.
I would target 50cm/2' of trunk and then the airlayer just above (in case the pic makes me think that the tree is higher than she really is).
