 Why are my cakes two-tone?

I've read the FAQ's, I've searched the forum and I have yet to find an answer as to why my cakes have small burgundy colored specks in the myc growth.
This is the only jar which I shook, the reddish color was the initial growth before I shook it.
...
Another cake:
...
and a 100% crop of the first jar:
As you can tell these are wet birdseed quart jars which I pressure cooked at 15psi for at least 90 minuets. The metal lid has a center injection port (ie a large hole) and three small air exchange ports around the sides with tyvek covering it.
I sanitized the syringe which I used to inoculate from my multi-spore LC by cleaning it inside and out, filling it with 70% alcohol, ejecting that, and filling it multiple times with both boiling water and rubbing alcohol.
Then for all the actions I did with the syringe (i.e. filling up with LC and each time I injected that into a jar) I heated the needle, placed it in a shot glass of alcohol, wiped the soot off with an alcohol soaked paper towel, dipped it in the alcohol again and with it still dripping wet I executed said action. I think the sterility was great during inoculation.
Could this be some sort of metabolite or mineral deposited on the myc?
Thanks

It could be Neurospora. It most definitely is not healthy mycelium growth.
Check out "Pink Mold; Red Bread Mold – Neurospora" in the "What are common contaminants of the mushroom culture?" section of this forum above.

Pink mold does not sound right, these jars have been growing for a few weeks and they are still not fully colonized. Lipstick mold might be more accurate but I guess I shall see over the next week as I wait for them to fully colonize the jars.
I just tried to smell the jars and all I could pick up form it was a weak Oust smell.

What kills me is that the growth almost looks like normal myc strands that have been covered in some sort of pale purple flakes but I'll take your word for it  They sort of give off a sweet and sour smell.
What would be the best way of salvaging my canning jars? I'm tired of having to throw them out.
