(Noobie Question) Are these contaminated?

Hi! This is my first time trying PF Tek (with GT and B+) and one of my jars, which is the furthest colonized, is just FINALLY almost done colonizing and I think it’s contaminated (((.. I had a couple of of other jars I noc’d up around this same time which I threw away cause nothing grew after a few weeks and there were weird squiggly line shaped things in the other ones.. Could someone please take a look at this one for me and tell me if it's contaminated? I'd just like a second opinion. This one jar has numerous signs which lead me to believe it's contaminated... Many of my other jars display some of the same fuzzy growth around the sides of the mycelium as it spreads, as well It has some growth sticking to the side and it’s starting to look very fuzzy, and I think just this one and possibly another are starting to look green... Jars are sealed but nonetheless I separated the ones I'm suspicious of. I don’t know how I messed it up that bad if so lol... here’s some pics of the one specific jar I believe to surely be contaminated..

and for reference/just to double check, here are some of the other ones I believe may be contaminated / end up being contaminated.. Is the fuzziness a sign of contamination? I've been researching and I've found lots of mixed answers with some saying the fuzziness is a sign of contamination and others saying fuzziness is a good sign. Almost all of my jars which I'm not sure whether they're contam'd (at least don't have the green) are fuzzy like this... Also, WTF is that silver looking thing?

Notable Update: I wrote this post last night, however it took me until this morning to successfully upload the images and get around to posting it. That being said, last night after writing this and doing tons of research, I came to the conclusion that maybe my cakes were too wet / not getting enough airflow and therefore mildewing, possibly causing the fuzz? I loosened the lids a little bit on most of the jars with the fuzz ( Including the jar from the top image, with the little bits of green at the bottom of the jar ). Since then, it appears the fuzz has lightened up at least somewhat, and the jars continued to grow overnight at what seems like a better rate. However, The green in the jar in the top pic seems decently more visible/bold... So basically I'm assuming I should just toss this top jar? or any jar with any sign of green in it? and what about the fuzzy jars/ the one with the silver thing? Should I keep them and keep the jars loose in an effort to save them? is it possible? or should I just trash those as well?
EDIT: Pictures added to site rather than Imgur
Sorry for the noobie question, haha. I'm a beginner who's very interested in this and I'd love to figure out what I'm doing wrong, how to fix it, and more about perfecting the craft. Any response is appreciated. Thanks so much in advance, -MJM

As a rule of thumb, if you see green, start over.
I have my own rule about clicking questionable third-party links, so I can’t help much unless you upload the images to the site.

Understandable. I added some of the pictures to the site instead

Hmmm I actually see no green at all. Looks like bruising (it can be blue or teal). Also, it seems to be 100% colonized🤷🏻♂️
I’d birth it now

AWESOME!! I was thinking maybe that was the case. I wasn't sure if it was maybe dark green so I wanted to check.. I've shaken them like hell to be honest haha... I'll lighten up... I also just wasn't sure if it was possible for cakes to be bruised.. What about the 'strands' (for a lack of better terms) sticking to the side? or the fuzziness? Are either of these bad news? It's about 100% colonized... just one teeeeeny tiny bit on the bottom of the cake where I can still see a small bit of verm... That's primarily where it's fuzzy... the border between grown and substrate. I plan on birthing at least that one tonight... we'll see where it goes..  Thank you man

UPDATE: Birthed it last night.. Smelled mushroomy but as I said this is my first attempt, So I don’t know if I would even be able to tell the difference between the smell of a normal cake/a contam’d one... I washed it under water extremely well before birthing and I believe bruised it a bit more.. Same color as the blue on the top is slightly on the stringy growth on the sides..
ANOTHER NOOBIE QUESTION: I began wondering this while birthing this first cake... Is the likelihood of contamination the same during both the colonization and fruiting cycle? Or once you take the cakes out of the jar and put them into your FC, does the likelihood of contamination increase since it’s open to the air, besides the verm layer? Or does the likelihood of contam decrease once you’ve made it through colonization process without issues?
Thanks in advance for any answers! Excited to see what happens with this cake

After the substrate/cake has been fully colonised it has a much higher contamination resistance. So once they are birthed after fully taking control of all the substrate (so no other competing organisms can take hold) they are a lot more resistant until the resistance falls again due to a number of different reasons (not limited to these) : * bad environment (humidity, temperature, etc) * bad genetics can play some role * age - after a few flushes most of the cakes get "spent" so their immune system deteriorates and they eventually start getting contaminations so they should be disposed of. Ideally you always want the expired cakes reach this natural stage.
During the sterile colonisation stage we need to provide mycelium with a competitive edge by keeping every other organism out
