well...To start with, not enough nutrient causes the yeast to have a hard time doing it's job. It can cause "Off" flavors, and a slow ferment. All of that is splitting hairs at this point. Now the issue is how does it taste, and what is your ending gravity? If the gravity is low and it seems stable, bottle it. If it tastes good....and I'll bet it does, don't stress now about not having added nutrients 6 or 8 months ago.
Post a picture......better yet, send us some to taste test for you
