I forgot to update this...I finally figured out what it was! I was residue form my brew kettle. I noticed that there was a whitish film of something on the bottom of my brew kettle. This is from not scrubing after brewing...only rinsing. As I cleaned the kettle it was obvious that the mystery stringy things were part of this film that broke free during boil.
No it was just accumulated film from prior brews. I would just rinse it out and call it good which left a film of residue on the bottom that was very hard to detect until you actually scrubbed on the kettle
