Where put the wire for training and why are some stems so short?

Waut another 2 week the olant will be establish weel routted and have enought growth. You can always lower the leaf lwer then its internode to force the growth of inrernode.. what most oeople don't understand is the interaction of hormone balancement with positioning of leaf stem and all.. that wieri g belongs to the bonzai world sur looks cool. I prefere to remove less has possible. I grow my plants very flat canopy without toping when i want to.. its all about playing with hormones. But i would wait 4-5 internodes. Has not to weaken the plant by toping and removing more then should be preventing it from breathing and stop transpiration (stuning and death)
