Hey all,
. the one consistent thing on all brews is there has never been bubbling during fermentation but a big bulge in the fermenter and the gravities have always followed what they were supposed to do.

A big bulge in the fermenter! Are you fermenting in a sealed container? If so therein lies you problem. In first stage of fermentation yeast needs oxygen and later it becomes anaerobic ie not needing it. As soon as fermentation is under way remove the lid and when it slows down replace it with an airlock. When the desired FG is reached transfer it to a second FV and leave it for a further 10-15 days and then bottle/barrel it. The proceedure for lager is slightly different but your recipes are all top fermenting. Hope this is of some help.
edited cause spelling of anaerobic
This is definately news to me, as soon as I pitch it straight into a plastic container with the lid on, isnt that what everyone else is doing?
Also attached is my water report so if anyone has any suggestions on addtitives that would be much appreciated!
