I am new to the orchid growing family. I am trying to nurse back a Phalaenopsis orchid my close friend brought back from Hawaii and her mother had neglected over the past few months. I have it in an inhome greenhouse where I am keeping the temp, light and humidity levels where recommended (60 at night and 75-80 at day, light on a normal day cycle as I don't have a south window that gets good sun, and humidity at 40%). I notice the leaves close to the stem seem healthy but as they get closer to the tips they seem to feel softer and more like rubber and are much more droopy than ones I see in pictures. Can anyone give me advice as to what is causing this and how I may treat the problem. There is a nob on the stem that is green and seems like it will sprout. I just repotted it last week after trimming the dead roots off as directed in a book I read. I know it hasn't been that long since it regained care but how long do I go before I change care on it. Any advice would be appreciated!
