What to do about Yeast?

So I have ran into what appears to be my first yeast contamination. Mycelium seems to be growing fairly well or perfectly well instead of stallings which I expected. I shook a jar to see what would happen and its recovering fairly well.
I feel like I should still toss them but I have 14 jars that this shit got into. Something went way wrong inside my SAB apparently because my agar inoculated with the same colonized grains show no signs of contams from 3 grains I sampled.
Here are a couple of pictures..

What are your thoughts??

I had yeast once as well. I run lots of tubs, and always have back ups. However, I let that particular jar run it's course, just for education purposes. I found that my myc overtook, won the battle with the yeast, perhaps even consumed it. There was no metabolites in the jar, after colonized. However, I just tossed it. No experience with fruiting or expanding that jar. My myc plowed through it, and no visible signs of yeast, jar looked great when finished. But I did toss. Once iffy, always iffy in my book. Weird thing about mine was one jar showed it, 30-35 hours after PC, in line for G2g. So it was still sealed ( perhaps the ring was a little loose after cooling, I can't remember) the 9 other jars, nothing. One and only time.

Cube mycelium will fruit with a yeast contamination. its not as bad as mold or bacteria

Wow. Thats good to know. Is there anyway I can be safer about spawning this batch of grain. Or would it be just as safe as clean grain spawn once 100% colonized? I'm only used to dealing with trich.

cubes will fruit off mold riddled substrates im not sure what you mean by not as bad.
spawning those would be a bad idea. that yeast will go to town and stink up the place.
top fruit or toss imo.

I would throw the grains out. Yeast is no bueno in my book.

Had it before, can work out. Anything spawned from it can also mold out very fast.

I guess I'm going to toss these. I have good clean agar going that I can use without setting me back too far. It won't be as fast as G2G but its better than starting from scratch. I have a good monotub going so this batch isn't crucial.

Man... I keep watching the growth and its growing so well that I'm having second thoughts. I'm no noob... but am I being dumb wanting to fruit these?
Just give it to me straight. But I'm also going with the majority opinion because I'm at such a crossroads here.
Here are some pictures of the jars..

This is the one I shook 2 days ago...
 *welp.. that pic is blurry so refer to the one above, jar far left.

I've seen some tc's say send it with yeast contam. Not a massive deal, yeast is everywhere around you already so spawning a tub with it isnt gonna infect ur grow area or anything.

Update on these 14 yeast jars...
After a shake roughly 70% they recovered quickly and hit 100% with no issues. I popped one open and it smelled like good, fresh mushrooms. I decided to try mixing up a tub and every subsequent jar I opened smelled perfect as well.
Fast forward to... well now. And I have 3 of my 56qt tubs pinning quite well. Not as well as some previous tubs from this same GT culture but definitely not worth tossing. One may even pull a decent canopy. In short. Im glad I kept all 14 jars.
I can't say this is a recommendation to others to run yeasty jars. But it did pay off for me.
I'll post pics of the 3 tubs hopefully tomorrow. But at least sometime before I harvest.

Sounds like a perfect excuse to start brewing 😜

It's funny you say that because the yeast literally made me think "why have I never gotten into brewing moonshine (or beer)."
Working with rye, agar, Mason jars and now yeast 🤣🤣🤣 I've got to be about half to moonshine. 😁😁
I'm looking at getting a kit for my B-Day in March.

Well, you're halfway to beer at least 😜 gotta get a still to make shine.
Start with beer or a barley wine, get the whole brewing process down first, and then move on to distilling.
And hey, if you're really feeling squirrelly, give us a log of the process 😁
Bonus points if you use the booze for cultivation sanitation and tincture/infusions

We will see. Would it be foolish to skip the beer/wine introduction? I am much more interested in moonshine. But I would have to be able to do it indoors most likely. Its not the best area around here and I don't have a garage.
But anyways. To get back on track a little.. here are the yeasty jar tubs. They smell like any normal tub. No fresh bread smell... 😕
I should also mention that these are the first tubs I have ever used a 1/4 inch top layer of hydrated coir to cover exposed grains.
Before, I left grains exposed after the spawn/sub was mixed. I pulled several canopies that way. Until tubs were triching out at 98%+ colonized. Im guessing from the exposed grain. Suuuuper bummer to watch a tub get that far and the VERY last patch turns green OR a small patch turns green a couple of days after being solid white.
With the 1/4 inch top layer these next 3 subsequent tubs made it to 100% just fine but the pinset/flush is not as great as when I left grains exposed with no top layer.
🤷♂️🤷♂️🤷♂️🤷♂️
Tub 1:

Tub 2:

Tub 3: (this one is iffy to me because of the grey whispy myc in the center. Maybe its just thin?)

Cheers! 🍻
