Is this contamination...?

Please, more experienced people, i need your opinion on these 2 rye jars. Pictures show them exactly 2 weeks after inoculation, syringe to grain, Cubensis. Are they Healthy ? If not WHAT contamination is this ??? They look fine to me, don't smell bad, but on second picture (jar 1) you can see some kind of yellowish tint. Is this normal ? I'm surprised at this rate of colonization if they are good.

Jar 2

It's hard to tell sometimes in pictures, but I think they're okay.
The only thing that would concern me would be the wispy, kind of gray growth like in pictures 3 and 6.
I've had stuff like that pop up in a couple jars and it very quickly overtook the jar. I think it was cobweb, but I'm not sure.

Thanks. Yes that grey growth scares me. Could be bacterial but it does not seem to spread. Also jar smells just fine through little hole on the lid. Could it be metabolites ?
I don't want to trash it yet, please people, I need advice on these.
Edit: we could be referring on two different things, I on lower part of the jar - kind of yellow kinda slime and you on upper part of the jar - spider like gray growth which is really expanding and resembles cobweb.

Not trying to be dick but that jar is fucked. You wont even see one fruit.
Can see the classic bacteria issue with: --that one seed that wont colonize. Excessive condensation on the insides. The mycelium looks like icecream on the bottom. If your grain looks like this against the jar and not being colonized my the mycelium is not a good sign.---
The wispy grey mycelium is some kind of mold, most likely will turn green after a shake or after spawning.
Also it looks like you got bacterial cube mycelium going up from the bottom and trich comeing down from the top.
I can see your main vector of contamination assuming you just put tinfoil over the top rather than a filter or polyfil.
