Been 2 weeks and 2/4 grain bags have yellow fuzz. Looks bad... holding out hope it's myc piss but curious to know for sure. Thanks for any feedback!

Can't tell if it's metabolites(myce piss) or if it's some yellow mold. Either way it's doubtful that bag will finish colonizing.
Did you inject a spore syringe into this bag?

Yeah, I used a syringe and SAB.
Edit: Is there another way to inoculate grain bags like this?

So spores aren't sterile. Mushrooms grow in open air so there's always some contams in them coupled with water in the syringe and put on grain it's a dice roll for disaster not in your favor.
If you're going to work with a syringe I suggest you check out these links https://www.shroomery.org/forums/showflat.php/Number/27952058
If you want to work with grains then you have to learn agar so you can isolate a clean culture. Lots of agar links in my signature to help you there.

Thank you for your feedback and the links. I didn't realize that grain bags and spore syringes weren't ideal. What makes BRF cakes better for syringes in terms of minimizing contamination?

Iโd I understand correctly, PF tek is more resistant to contamination because its nutrient profile is less complex than whole grains, and the water from the syringe gets absorbed by the BRF and vermiculite, which reduces the motility of any bacteria that rode in with the spores. Why spores to grain is not ideal.

Imo I think brf cakes are better with it because the flour and verm soak up the syringe water better leaving the spores in a better surface condition smaller matrix of inoculation points. With no standing water the contams have it harder.
Vs on grains the water stays wet on the grains making it easier for contams to grow and a less than ideal surface for the mushroom spores.
Just my take on it though.

I vote aspergillus. Definitely contaminated and a goner, sorry for your loss
