So the problem continues. I was using Earl Grey tea previously, but this batch was normal black tea. The SCOBYs that form are thin and break up easily. Some of the existing ones are getting weaker and getting holes.
I have pictures of the appearance. The SCOBYs just don't seem to be forming on the surface like normal.
The surface in the bigger jar shows how it's not forming well. This is after at least two weeks, more like three, so it's not a matter of patience.
