This Orchid Is Driving Me Crazy !!!!!!

[jnoble]

Hi Everyone, Im a newbee in all this of growing orchids, but Im really woried about this one. the first thing I notice was the leaves are getting really soft or flaccid and the roots are getting kind of dry like a paper, I water this plant once a week, I dont know is this is to little water or to much water, or maybe the way she is seed. I live in Puerto Rico and the weather here is kind of extreme, rains every day and is really hot. honestly I dont have a clue of how to keep an orchid. could someone please help me??
