Suspect looking oat jars | Advice Needed

Hello all, I have some grain jars that are looking quite suspect to me. I'm still inexperienced so I'm seeking any advice that you'd be willing to gift me.
3 jars (A, B & C), Inoc. by agar wedge.
Oats prep: Bhod's Ez af tek, no soak, no additives.
Numbers on photos are for easy reference, letters representing individual jars.
A looks to me like some kind of contam and I think I should turf it, but I figured I'd check and see if it's maybe a weird thing that can happen to grains, or if I've made a specific mistake that I can avoid.
B has ridiculously thick growth of some kind that is smooshing against the glass to the point where I cannot discern if it's contam or not. Tried to get photos of the bottom where the growth hasn't reached yet s you can see its structure better.
C is a bit more subtle, but if you look in the photos you can see this line where the rhizomorphic stuff hits what I'm hoping is a buffer of tomentose growth from a separate colony (if that's the right terminology... sorry if it isn't), but I'm worried that it could be hitting a barrier of white mold. The line goes quite a ways around the jar, and I've had white mold before.
Any and all observations/advice are gratefully welcomed.
Thanks for reading!

Those all look bad to me.

Thanks for the reply!
So they all seem contaminated. Could you elaborate on what the problem with C is particularly? Perhaps B as well. Is it mold or bacteria? Perhaps a hidden contam on the agar plates? Any ideas?

C looks like it has some sort of mold in it. There shouldnt be dense splotches like that. It should all be uniform and clearly directional.
B is heavily bacterial. The goopy looking stuff are bacterial colonies. My bet is your grain was too wet on that one. The other two were probably inoculation.
Did you vent your PC?

Thanks for this! So you think the weird barrier line in C has mold on the other side? I'm not sure I can see the splotches in that one.
Yes I did vent my PC, for 15 minutes. I give it an extra five because my stovetop is a bit weak. Presto 23qt.
I can agree with them being too wet though - I'm certain I didn't wait long enough to dry them off post boil before jarring and PCing them, in hindsight.
It's hard to tell from some of the pictures on here what a fully colonized jar is supposed to look like, so I may post more jars upon inspection.
