Thank you for your encouragement! I got a small pot with a net pot inside and transparent plastic outside, some new mix (with Sphagnum Moss, Pink Bark, Hydroton, Sponge Rock, and Cork Chips) and SuperThrive. I just repotted it, have not tried SuperThrive yet, but going to with next watering. It's doing okay, I think. Nothing has turned yellow or black. It looks pretty much the same since last week. I will take some pictures tomorrow.
