As I mentioned in my intro thread, I'm new to orchid growing, so I started out with a phal hybrid (the tag wasn't much more specific than that). I have it growing about 2 feet from a north-facing window, watering about 1x a week. Relative humidity in the room goes from 62-71%, and the temperature stays pretty constant between 62-70 degrees F. I was wondering, are there any indications to look out for, to see if the light is too much or not enough, if I'm overwatering or underwatering, basic indicators of health?
