Phal Yellow Leaves hopefully solved

[orchidlvr2]

I use pebble trays and humidity trays. The latter is helpful because I don't need to add water as often. Phals are relatively easy to bloom but I have found that you need a day/night temperature differential of 10-20 degrees to get them to bud. I have put mine outside in the fall for a couple of weeks (I live in central Illinois) in order to get that nice drop. Hope this helps.
