Yellowing stems and white dots on leaves
I've had this Phalaenopsis orchid for almost two years. It's bloomed about 3 or 4 times.
Recently the flowers have wilted and fallen off and the tips of the spike and secondary stem (I think that's what it's called) have started to turn yellow. Should I be concerned about this?
I am also concerned about these white dots on two of the leaves. They have been there for a few months... They appeared after I repotted the plant. I was going to ask about it, but then the plant started to rebloom. What are these things? Was that reblooming just a last hurrah before the plant's demise?
I've posted some pictures here:
Thanks to anyone who can help...
