Can't quite figure out what to do for Phalaenopsis

[alsorchids]

Thanks for the advice to all of you! The orchid in question has been repotted two or three times and is now in medium bark, ( no bark break down seen). Sorry folks I was not clear on that point. I use a plastic pot with good drainage , but not a clear pot. I agree the phal was too wet a couple months ago and with this plant I did not check the roots in a long time. My other orchids I do check to see how moist they are, so I will plead guilty there. Now I have been trying to dry this phal. between watering by sticking my finger in the bark a couple inches. Phillip, when repotted I did use sterilized scissors to trim dead roots, they were soaked in Python Fungicide and no healthy roots were broken. Roots were already wet before repotting. I tried to be gentle in repotting and I did not pack firmly for fear of breaking the healthy roots left. The phal. leaves are flaccid and the new growth leaf which started when I lost the first leaves two months ago is firm but not growing. Well water is used with all thirty orchids, but no testing has been done in probably years, (we drink this water). No mines or industry for many miles around our water source. This plant was doing so well its what seemed to be sudden decline surprised me. Pictures to follow shortly. Thanks again all! AL P.S., Camille great advice about clear tenting this orchid, I'll do that!, and it is staying warm in indirect sun,(not under 68 degrees F. or above 75 degrees F.).
