Sandra, sorry to hear about another orchid misadventure , it's probably from the nursery. I once bought a mini phal , put in on the table that night. By the next morning, the whole top medium was covered in white mold. I repotted it , but there were no roots..and after an attempt of shooting out 2 new little leaves..the orchid god took him anyways.
So now I try to look into the pot after I get home from the store..to see if everything is in order in there....
Your plant shoud be fine...I've had some looking worst than yours and they ended up thriving later. I've heard somewhere that if the plant is too big, you could wrap the bottom with sphag and stick it in a pot instead, but I'm not sure how that will work with your new growth coming out.. I don't think it will like being wrapped up.
