Pink specks in my yeast starter?

I created a 2L starter (WY1968) a couple of months ago, but had to push off brewing until this week. I washed the yeast back then and created a 1L starter last night using the washed yeast. This morning, I noticed some pink specks at the absolute bottom of the Pyrex beaker… Any idea as to what they are, and if this starter’s been “compromised”?

Thanks!

[edit]
They almost look like granules…

Iron from the water?

Any chance of a good close up photo/s

Unfortunately, no… And the starter was looking really gray, so I decided to dump it. I had a WY1945 smack pack around, so I made another starter that looks much better.

Great decision!
