Scoby brown spot, is it OK?--new to brewing--

[BeekeeperGreg]

This is my second batch, the first on is a quart jar didn't have the brown spot.
Can someone let me know it the brown spot is good or bad?
Thank you so much,
Greg

Mine always have lots of brown spots.

When new it is so nice to have support.
Now I can blow up bottles.
Thank You.

Merry Christmas
