Is this contamination?

Hi All, First time cultivator here. I'm wondering if my spawn looks contaminated? The reason I'm suspicious is because one of the jars has some pins forming, but there also seems to be a section of the WBR in that jar that isn't fully colonized. The other thing I'm unsure about is the fuzziness at the top of the WBR -- it seems more fuzzy than most pictures I've seen. Sorry for the newb question, but I just can't figure it out myself, comparing pics of healthy and contaminated myc to my jars. I would just birth them and see how it goes, but I don't want to shoot myself in the foot on my first time out.
Thanks in advance. Your thoughts are much appreciated.

Yes, that looks bacterial. I am making that determination due to how much moisture/metabolites are forming on the glass and some of the rice is beginning to look "slimey", along with how the myc is "freaking out" going all rhizomorphic. I can't really tell from your pictures what you mean by the top being more fuzzy than you expect. Healthy myc can be quite fluffy, in this case though I think your spawn is fucked.

I agree, those look bacterial to me too. I'm sure some people have success with rice... but picking another grain like rye, wheat, or oats would probably make things easier for you.

Hard to say.. it looks like its way too wet. But there is definitely some mycelium growing. I would wait alittle bit before you throw it away.

Well, I waited a little longer to see if a contam would make itself obvious. When they looked fine a day or so later, I opened two of the three jars (I waited 2 more days for the last jar) and carefully checked the smell. Luckily, they smelled like straight up mushrooms so I was pretty confident they were fine. I had originally planned to spawn to bulk, but when I downsized jars last minute to fit my pot, I forgot to take into account that I wouldn't have enough spawn to be at a 1:5 ratio or better for the monotub I was planning to use. And since the jars had slight shoulders, my best option seemed to be in-vitro fruiting. So, I sprinkled them with verm and popped a ziploc over those bad boys and have been misting 3-4 times a day since the 24th. Well, this morning I saw my first two pins! Hooray.

I'm happy to have gotten this far and have since started some PF cakes in wide mouth half pints that I will put into a sgfc. Thanks to everyone for the advice. I also ordered a 23qt PC that should arrive tomorrow and I will start over with a proper grain tek. I'm thinking BOD's easy AF Oat tek.
