Bellow are some pictures of my two Phalaenopsis orchids. The smaller one I've had for about five months and the bigger one was purchased just yesterday. They both have wilted yellow/orange leaves on the bottom. Is this just normal as they shed old leaves and grow new ones or it it maybe something else (watering, fertilizer)? And should I wait until they are completely dry to pull them off or should I cut them off?
Also, my little Phal has an odd new growth. It looks like a stem but it's coming up from under where the roots are, it's not attached to the base of the plant like I'm used to seeing. Is it a wayward root?
There are pictures below of all of this.
Thanks for any advice/observations!
