Just got back ...
And the tree is still brown, but it stopped progressing though. Top buds are green and growing.
I think I was over watering, as I just bought it. I regularly water it once a day and mist it for humidity. I also noticed that the soil was in clumps, not good quality I think. And so I was hesitant to change it as I just recently transferred it from a pot bag to a pot.
I'm in the Philippines. The tree is in a nice shady spot, no direct sunlight.
