gifted Gram. tigers paw, any advise

[moonharvey]

Hello.
I was gifted a lovely Gramm Tigers Paw "Greenbuck" and "green tiger" cross (I only discovered what it was with the help I got on the beginners board, the florist that sent it said it was a spider orchid).
I located this board when I was trying to figure out why the tip of it's leaves are turning brown. So far the concenses has been minerals in the water. So to save time I have included my original post....

The question I have now that I have been directed here is is there anything special I need to know? What is the best fertilizer schedule, My other orchids are once a month with super thrive in all other waterings. Is there anything in particular I need to watch for? Any and all advice will be appreciated.

Hello I am new to this forum and fairly new to orchids (I have 2 happy phalaenopsis for a couple years now). I recently received a beautiful new orchid as a gift but have no clue as to what it is. I called the florist that delivered it and they said spider orchid (so descriptive I know). So my first question is what is it.

My second question is whats wrong with it?!? I watered it with a small mixture of super thrive the day I got it and it seemed to be happy but since my only windowsill that gets any light is full of my phalaenopsis and a bonsai I moved it to my boyfriends house a week later. It now sits in a window that gets direct sunlight in the morning. I watered it with his tap water....which he now tells me is hard...and no super thrive....because I forgot to bring it. That was Thursday; now today (Sunday) I re-watered because it was dry and noticed the tips of the leaves were brown/black and dying. There is one leaf with a brown spot in the center but it looks to be a different type (maybe sunburn?)

Please help. Im not real sure what to do for it. Any and all help will be appreciated. I have included lots of pictures so you can see the blooms (there are lots of them) as well as the base and the brown places on the leaves...as well as one picture of how big it is (my boyfriend standing next to it is 6'2" for reference).

The crazy news....the person who gave it to me says they have another really interesting orchid at the flower shop and is considering sending it to me too! I need HELP!

I rinsed it with spring water and let it drain in the sink for an hour and I have moved it to a less direct light spot.
It is in a soil medium inside a smaller pot inside the decorative pot. The moss is just on the top to keep in moisture. It had several buds that had not flowered yet when I got it but after the first watering with super thrive they all opened up. I have not lost any flowers since I got it.

Moonharvey,

This is not my primary genera, but those leaves do not show typical "watering when dry" symptoms. It may be just the reverse in the roots rotting in the media they are in and not able to get water to the leaves at all. The yellow lower edge may also suggest a bacterial problem.

When it is through blooming, my suggestion is to repot in the appropriate mix, NO SOIL, although what appears to you now as "soil" is probably a bark mix. Meanwhile, do not over water your plant. More orchids are killed with too much water than with too little.
