What might this discoloration be?

[mike28086]

I’m asking about the black color on the trics. ridges, any insights would be appreciated in advance. It is not from being too close to the lights, this cutting is from the bottom of the plant.

regards,

thought I might add some other images from same bud shot, to see if you find anything else that may, or may not help? thanks again.

That just looks like purpling / coloring at finish to me.
I don’t see anything worth worrying about. Just my .02 cents.
