Blueberry Gum #2 seems to be doing rather well.
I'm considering keeping four node levels, for 8 main branches. Right now she's forming the fifth node, and I'll be waiting until the sixth before topping.
She has been rather resilient and has not required much attention, despite me giving the attention regardless. Definitely not being temperamental right now, and this is what makes me happy about her. I can put more focus on the ones I'm worried would give issues.
In terms of height, despite being germinated later (and starting Week 1 of veg 4 days after the others in the tent), her canopy is just as even; once I've topped her, I can imagine she would be much easier to train with a trellis net installed.
