u/Condiiments

I got a scoby from a local kombucha brewer which is pictured here (the little round egg yolk lookin one).
Because it was small I made a 1L batch, and this larger scoby began to form on top. When I topped up the batch with more tea, it stopped floating for a few days, then rose to the surface but kept this scrunched up form.

Now I’ve reached the point of decanting into bottles, I see these brown splotches where the scoby seems to be touching the surface most.
Also, the initial scoby has developed what looks like an air bubble (?) in the center.

Is this safe to continue topping up and consuming?
Or do I need to start over?

Thank you!
