I had a rash of metallic notes a few years back and located their source to a post ferment use of copper tubing. Any recent changes to your equipment, method whatnot...?

I've also had hops throw metallic flavors.
I had to stop using willamette hops because of perceived metallic flavors, both by me and by judges in competitions.  It seems unlikely that you would have used the same hop variety in these three styles, but it is worth mentioning.

Not sure what kind of equipment that you use, but do you tear down everything and clean after each batch? I have Blichmann 3 piece ball valves and you'd be surprised what can find it's way in there but thankful that I can easily take it apart to clean and inspect before the next batch.

You could always do your next batch with RO or distilled water and see if you get the same thing.

I would suggest trying this. Adjust the water with gypsum and calcium chloride and see if the same flavors show up.

I got to convince my wife to do that.
When was the last time you changed your tubing?  I had a metallic issue a while back and after a strong cleaning of my carboys and kettles and replacing worn pieces of tubing and plastic equipment it went away.  Just a thought... :-\

I have gotten a metallic taste off my tap lines when I've let them go too long.  It might be worth a shot.

Tubing is fine
 Replace it very often. I think its just a problem that could be a 100 different things. Everyone says hops, water, tubing, ball valves, chlorine...honestly its probably a combination of all of that. I can't pinpoint it. Its really frustrating because this could take 20 batches to fix...all of a sudden the beer hasn't been the same. Can't figure it out. My procedures and cleanliless is spot on.

Get some to me.  Tasting it might provide a lot of info.

If that were truly the case then you wouldn't be having issues.  Its not 100 different things if its happened to three different brews that are three different styles.

Could be a pH issue associated with a change in your water supply, causing some tannic flavors to leach out of the husks.

I just pulled a sample from the carboy. Wife and I agreed. Its an ethanol type flavor. Used Belgian ardennes yeast and fermented at 69 degrees. So im assuming those alcoholic flavors shouldn't be present. All note that the beer is about 4 weeks old. 1.060 og. 1.014 right now. That gravity hast budged since week 2.

Someone mentioned to me that it could be from an auto siphon. I don't think that's it because I tasted this before I ever racked it.

Could it be my starter fermented too warm?

Unlikely.  I hope you're decanting your starters.  Using 3522 that warm could definitely give you the fusel type of flavors you describe.  I use it quite a bit and keep it in the low 60s for at least the first few days.
