Yep.
I too grow Phals and Cats and have killed my fair share over the past several years. I remember when one of my first Phals passed on and I was heart broken. Then I found out that it was quite common.
If you have not killed at least a few orchids, then you are NOT a real grower.
My orchids now do much better after I moved them to my Kitchen (understanding wife who loves to look over her shoulder at the beautiful blooms as she is cooking.
) My wife even asked the other day "Are blooms coming on?" And I cheerfully said "Yes!"
It looks like I have another ill plant - Pseuderanthmum pseuper bloomer. My fault entirely! I did not bring it in soon enough (I have SO many plants) and it got exposed to temps into the low 40s on my screen porch. But has a min rec temp of 50!!
