Update. I do know what a Y is and looks like.
Brug 2 has some branching going on, but no Y. Is is though throwing some buds. Needless to say I am pleased cause I planted the seeds early last year and the plant is nearly 6 feet. It is Arborea species.
Note that the main stem did cease growing vertically, which was fine with me. I think part of it was bug attack.
