Short answer yes.
Long answer, its not as simple as selecting a desired ph and acidifying to get that ph. The sparge water chemistry plays an important role. My suggestion would be to read Bru'n's https://sites.google.com/site/brunwater/
and water by John Palmer.
Both will explain the role of the sparge water.
After reading both, I find Bru'n spreadsheet a great tool and gets things pretty spot on when double checked with a ph meter.

I will be shortly doing my first all grain brew. I have a PH meter in the mail and am trying to get as much information together prior to brew day. I think I need to buy both John Palmer's books. I will also check out Bru'n spreadsheet also. Thanks for your help fellas. Much appreciated.
How do I know if I am over sparging, causing astringency?

If youre using brew software and you folliw the volumes and fet the right volume into the kettle you should be over sparging.

'nt.
Shouldn't
I acidify mine very mildly with lactic or phosphoric. Occasionally I forget and notice little difference. Might depend a lot on your water - mine is vry soft and clean.

I have very hard water(bore) and also RO water and also access to town water if I bring some home from work. I was thinking of doing a 50/50 RO/bore water mix for my first brew?????
My bore water is:
PH ……………………………… 6.86
Hardness mg/l as CaCO3 ….. 260
TDS mg/l …………………….. 793
Conductivity us/cm2 ………. 1089
Iron mg/l ……………………zero
Manganese mg/l …………….zero
Nitrate mg/l …………………zero
I am intending to brew firstly American style pale ales.
My basic recipe is: (less hops and other non relevant inputs)
Batch size 26 litre
5.5 kg of grain
Mash, liquid to grain ratio 3.5:1
Mash in, single infusion full body, 17.5 litre
Sparge 16.19 litre
I am using Beersmith2 and was using a liquid to grain ratio of 3.5 to1 for the above. I was concerned at the 16 litre sparge re astringency. I have since adjusted my liquid to grain ratio to 5:1 to give me a sparge of 7 or 8 litres depending on my grain bill.
Manticle, how are you determining your sparge PH?

By estimation and guesswork.
If I was in a position where it was dire (eg. Shit hard water), I'd use a decent, well looked after pH meter but for my purposes a hop, skip, dash, cubit or beesdick will do.
