Salmon pink contam

I'm not sure what happened. This shoebox was doing just fine today in the morning. Here is a picture of it this morning

Then after misting the shoebox, I checked it some hours later and the fluffy mycelium from the lower left corner had a subtle salmon pink color . I removed it and this is how it looks like

It looks like a strong salmon pink in the picture because I had to remove a all the mycelium in the corner. I'm worried what could this be. It just happened so fast I don't know how to identify it.

Could it be a reaction from the mycelium to the water I misted/sprayed?

Yes, you are, and have been contaminated for a long time.
Looks like Serratia marcescens, a bacteria. That will create perfect conditions for trich and cobweb. Witch you have in the other corner.
Either your sterilization methods failed when you prepped your grains (and/or your MEDIUM) -OR- it was contaminated shortly after.
That bacteria comes from dirty feet, hands, bathroom towels, sinks, showers, mat, etc,
The trich in the corner is about to fruit itself.
There is no need to be poking at your grow either, especially before your substrate and medium are fully colonized.
Misting a tray during colonization, over and over, is no bueno.
most all the water it needs to colonize was already added during the prep of your substrate- so misting a tray, you just spawned, is just adding mold and bacteria.
If ye need help figuring out what steps need work- PM me with whatever questions.

Holy shit so Where's the trich? I'm not sure why the lower right corner looks green but is not in person I'll try to take a better picture tomorrow in the morning.
Is the white fluff in the lower left corner cobweb?
I'm pretty sure the jars I spawned were clean, it must have been my cleaning procedure for the coco and the tray where I failed.
Thank you for your help Civ I really appreciate your input, I'll be working to inoculate more jars now and start it over again or do you think it's still worth saving the tray? I'm pretty sure the consensus is to just throw everything contaminated but I've read in some places that contams can be treated with lime but I don't mind starting from scratch it just sucks to throw a tray I thought it was doing good.

Here are some pictures of today.




The contam is more of a yellow hue today. Is the fluffy white cobweb? It looks very different from the actual mycelium. I just want to identify what this is.

Yeah, especially when your contam is fruiting- eject. eject.
No gain to keep around. Its droping spores all over your house.
If your having slow colonization times, the vigor of the myc can be dramatically reduced by the time you spawn.
The only thing that does that to a healthy strain, is poor medium preparation- or poor environmental conditions for colonization/spawning/fruiting.
If you prep right, and spawn right, you wont contaminate.
... and dont mess with it. you should never have to mist a substrate, that isnt fruiting. Treat it just like a jar, IE, before a tray is colonized- leave it alone. You contaminate the uncolonized medium, in the tray, with each spray, and FAE. You also confuse the colony by adding FAE, during colonization. It will halt, if it thinks its time to go- and if it stalls, then contaminates will take residency up in the areas not colonized.
Are you using QT jars? Grow bags? Sometimes sterilizing smaller portions at a time, along with smaller spawns, can help make sure you get to full colonization, more often, faster.

I'm positive that I didn't sterilize the coco coir properly mostly because I didn't spend the time to meticulously do it as when I inoculated the jars. Horrible mistake.
Thanks for the tip, I'll leave the tray alone until it starts fruiting.
I'm using half QT jars, my pressure cooker won't fit QT jars. I'm inoculating more today and I'll make sure to not fuck up the tray this time.

You don't need to sterilise coir, just pasteurise in a bucket using boiling water

Yeah I did that but I'm not sure if I did it properly. I will make sure I follow every detail in the instructions I've found here.
