plain tap water??? have you ever fed it, think you wanna leave that water open so the chlorine can evaporateOK well the soil is old and used but it seems to be growing. I water it until water drips out of the drain hole in the bottom on the pot, I use plain tap water but I let it sit out in a sealed water bottle for the chlorine and other things to evaporate. When the soil is dry 2-3 inches down I water it.. I don't PH the water.
But the leaves do look a little yelow
Thanks,
