Hello! I am a complete newbie when it comes to orchids, so please bear with me. Recently (2 weeks ago), I purchased on a discount my first two Mini Phalaenopsis. I repotted them, changed their media and I cut the dried, old roots. I've noticed they now produce new, healthy roots, so that is ok.
However the first one developed these small black lines on the base of its newest leaf (on the inside of the leaf). I was wondering if that is a sign of a disease (a virus, or a bacterial infection of some sort).

The stem of the second one does not look that great; it has areas where is darker in colour (maybe it was not watered correspondly in the store). Also some of its leaves have small discolorations on the edges and in the middle.

Do you think these mini Phals are sick? Thank you in advance!
