Beginner needs some help with Wils.Tiger Brew

[flowersprg]

Hello,
New to the forum, I'm just becoming a lover of orchids, and I just got one of these beautiful Tiger Brew's from whole foods (just in case that's relevant). However the flowers are starting to die already, only one so far, and i'm wondering if I'm caring for it wrong. i know different orchids have different preferences for light and water, and i'm wondering what I should be doing for it. Can someone help me out here please? Thank yoU!
>>I also got a oncda. charlesworthii 'Mishima' and it seems to be doing just fine.
