No, I think Kktbva's was the first death. (I could be wrong...
) but there are the others with leaf and root problems that could possibly lead to another DIMP.
What I have noticed on the others was that it was taking too long for the medium to dry out, and it wasn't drying out evenly. Also it was getting chillier in the evenings. These Phals like to get wet, but dry out quickly. They also like to stay warm. When mine started to droop, the temp dropped in my apartment all the way down to 68 degrees. The medium was still damp and the Phal didn't like it at all.
