Thanks everyone for your support and advice. I moved my Phal from NW window to the South side of the house. Now it will be enjoying bright filtered light behind the sliding door. Do I need some kind of artificial light going on later in a day, after 5-6 pm? Any advice? It gets dark outside so early now... About fertilizer: I use Blooming& Rooting soluble plant food 9-59-8 every time I water it (ferti-lome brand). I use only distill water.
