Default Odd Consistent Off Flavor

Hey guys,
I have brewed about 12 batches so far. I have had some great brews, but a lot of them have not turned out so well. In all of the lighter and not so hoppy brews I have done (2 blondes, lager, hefe, & amber), I get what I would call an astringency. It makes your mouth cringe and is harsh. I am really becoming aware of this as my palate gets more refined.
A pro brewer noticed it in a stout I made, but was much harder to pick up on because of the style.
Aroma is great. At first the off flavor doesn't come on as much, then it really hits towards the end.

I mini-mash. I have done one all extract hefe and the same off flavor was there, so that makes it hard for me to think it's my mash. I use the same water every time, spring water from the dollar store. I have checked PH in the mash before and I believe it was pretty close to 5.3 or so. My sanitation is great

Any ideas? What to try next?
please help, my brews are not near what they can be.

Can you be a little more descriptive of the taste? What does it remind you of? Also, make sure you aren't pitching the yeast at too hot of a temperature.

do you ferment them at a high temp? lighter beers are less forgiving.

what's your fermentation temp? Can you control the fermentation temp? If not you may be fermenting too hot and getting the funk.

Sorry, it's hard for me to describe. It's not really a funky flavor. It's maybe like the bite of a coca-cola, but not that extreme. All of the other nice flavors become restrained. I will try to taste again when I get home and post more.
My fermentation temps are typically mid 60's to very low 70's. I use a converted freezer with temp controller. The most recent blonde got to about 72 with S-04 at peak fermentation. This off flavor is overwhelming it that brew.

Are you over carbonating all of your brews maybe?

good suggestion, but no. 30 psi for one day to force carb is all, rarely much more.

Do you adjust your sparge water ph ? It sounds to me that you may want to clean the dip tube in your kegs and maybe replace all the o rings if you haven't done that already.

I had a similar problem and it was my water. I know you said you use the same spring water but maybe try a different brand or something just to eliminate that possibility.

stocktires - I too am getting an off flavor across my beers, one that I cannot pin point. It seems more pronounced when I pull a few glasses every now and again. My thoughts are yeast settling but not sure.

I filter my water with a charcoal filter but will try campden (to eliminate chlorine) for the next batch. It can't hurt.
