First yeast starter

[Powerturn11]

Ok guys quick question. I made my first starter last night but severely missed my calculation. I did 1 cup of DME with 3 cups water and boiled for 10 minutes. I never checked the original gravity. I pitched one vial of white labs yeast into the chilled wort I used a mason jar topped with sanitized aluminum foil. My question is did using too much DME kill my yeast? I never got so much as hardly a bubble. I swirled constantly and when I woke this morning I did have a thin layer of yeast. Should I pitch this starter or just try again?

You didn't kill the yeast but the og of that starter would be around 1.07. Starters should be around 1.03 and I understand that you usually shouldn't reuse yeast that fermented a wort with a gravity of 1.07 or higher due to stressed yeast and possible mutation. Someone else may chime in with advice, as I have no personal experience. But I would say start again.

I've heard a lot of conflicting reports regarding this. Hopefully someone that has experience with this will chime in. Thank you for your reply.

Here is the yeast layer for what that's worth. I've read that if you have this yeast layer you're good to go. Not sure.

You probably made more yeast than you needed and stressed them out a bit, but it's really not a big deal. As long as you're brewing soon, they're ready to go. Just a lesson for next time.
