Metallic/Astringent OFF flavors in all my batches, absolutely stumped, please help me

Thanks for all the replies on my post, every bit helps in homebrewing. It's been sitting in the kegs for a couple of day's and the taste is not going away. I got my yeast from a local brewpub (may be the problem but it's a pro wyeast wit strain so...) I'm stumped. I would say it's a combination of water, mash temps, PH, and lighter kilned malts. Those lighter beers really give you no room for error. I just brewed a chocolate hazelnut porter on this same system and it is perfecto so back to the drawing board on those lighter beers.
