Thanks for the advice. I think I just had a few days when it was over-watered but it's holding steady since then. I have faith that the tie down plus a little heightened vigilance will see this tree along well. I finally have some benches setup on my rooftop garden which is the first spot up there I trust to be out of the shade, so I'll move it under a bench where it can get attention everyday whole staying out of high sin.
