Jesse i have had problems like you are describing when my Alk was sitting around 7.5, once i started dosing and able to keep it stable at 8.25ish things have been much more under control. If life gets busy and i start to notice lack of EP or bleaching more likely then not my Alk is too low. From what i have seen with regards to your pictures, i don't see RTN but i haven't read every single post, there is a lot of hot air on this thread! I have had plenty of RTN and tissue actually peels off.
