sounds like it was clean during fermentation then got dirty… bottling bucket? siphon? how about your caps? it’s in every single bottle right? that rules out dirty bottles i’d vote.

Its in most bottles but not all of them. The ones that are fine, haven’t carbonated well.

That points towards the bottles or caps. When did you bottle them? If less than a couple/few weeks ago the low carbonation could be simply a waiting game.
