I mashed too thin. Should I sparge?

[Aizkolari]

I'm working on my first partial mash right now, and accidentally mashed in with 3.5 gal of water to 4.4 lb of grain. Clearly this is way too thin, so now I have two questions:

1. How fubar'd is my brew? I know, I know, RDWHAHB. But seriously.

2. Should I not sparge to account for this? Any other corrective measures?

I'm 15 minutes into the mash now, so quick answers will be seriously appreciated.

You are fine. Proceed as planned. A thin mash can lead to higher than planned fermentability but that will be about all. Vorlauf and drain your first runnings and then sparge as planned from there.

How much wort have you collected and what is it's SG?

4.4 lbs of grain. What size batch were you planning?

It's possible your mash pH would be way off, but I think that would just keep you from getting proper conversion. I wouldnt worry about it
