Mold or Mealybugs?

Hello everyone.

Just purchased this orchid because I love the pattern on the leaves and of course the blossoms. While inspecting it, I didn’t see any signs of mealybugs present under the leaves, but looking at the roots this spot concerns me. It also just looks like mold though. Thoughts?

I plan to isolate this one to see if any appear at home before adding it to the rest.
