Hello, I cut some stems of my large cactus and repotted them individually like two weeks ago. Since then the stems have formed this black (kinda purple-ish) spot on the top of the cactus. Is this something that I should be concerned about or why does it do this?

Hi.
It looks like a Euphorbia Trigona Rubra or Purpurea which does have purplish/red accents on the arms/leaves.
But I would def touch it to make sure it’s not mushy and watch it for any changes to rule out rot.
I do not think that’s a problem though.
That’s just new growth
It’s normal
