what is wrong with this Phalaenopsis?
 

and what should I do now?

rescued from a friend a week ago, roots seem ok, suspect severe infection at truck/crown, but don't know how to proceed to save her.....

need help!

Did it have those spots on arrival? Are they expanding? What are your growing temperatures and humidity?

yes, spots existed when acquired. southern CA climate. stay outdoor during the day, but take them in garage throughout the night. need more time to determine expanding or not

Unless you heat your garage, the overnight lows are likely too cold for phals. to be happy. They prefer to stay above 70F at all times. They’ll tolerate 65F if daytimes are higher, but they don’t do well in cold temperatures. I lived in different parts of San Diego over ~25 years, and all of my garages would have been too cold in the winter.

It must be cold for Phals in the garge. I am also in San Diego, my Phals were in garage but I had to move them to basement when temperature started dropping below 60°F at night in the garage.

Yes, I agree. Part of the answer for sick Phals. is almost always keeping them warmer.

I will put them in the living room...man, this is harder than growing a kid! :D

Your kids must not have reached teen-age yet.
