Beginner Cultivation Question

First time post.... Be gentle. I have done a lot of reading prior to posting but could do with some help. I have limited experience with mushrooms but am well versed in microbiology cultivation and have a fairly well equipped lab.
I am growing golden teacher from spawn (not spore). I have two batches going that are slightly different. I am growing in a grow tent that was disinfected prior to use with low wattage fluoro light. Air exchange is achieved by exhaust fan on timer. I have a humidifier with a controller and keep the humidity in the 90% range. Temperature is around 20-21C
The first batch the spawn bag was propogated off a purchased kit (the one I used below). I took some of the spawn bag and mix with sterilized grain spawn. It was mixed with 8 parts coco coir, 1 part worm castings, 1 part used coffee ground, 1 part vermiculite. It was sterilize at 15PSI for 3 hours. At two weeks it was fully colonized and I moved to fruiting chamber. I did not case this one. 3 days in the fruiting chamber I am noticing a slight yellowish/off white tinge on the top. Is this normal and is one of my conditions off (eg humidity). It is growing in a plastic tub directly in grow chamber. I do not mist.

The second one is from a kit purchased. The substrate is straw. It to 2-3 weeks to colonize straw from spawn. The straw was pasteurized in pressure cooker. I cased using sterilized casing (15PSI 3 hours). It took 10 days for me to be comfortable that colonization was complete. The kit came with a cover but I have not used it as I didnt think it would be necessary growing in humidity controlled chamber. The only thing i have slight concern is that on each of the two main growths there is beads of yellowish covered water. The rest is snow white.

Questions: 1.) Do these look ok or am I worrying over nothing 2.) Should I cover them even though they are in a humidity controlled chamber.

The yellow could be completely normal by the way you describe them sounds like metabolites. Like the stuff that can't be consumed is how i understand it. Although I cant see your pictures for some reason.

that shit looks like a trich bomb just waiting to happen. also that big ass blob aint a good sign either.
stop buyin shits and check out bods teks and get to making all the shit urself and make up some agar and do it the rite way from the start. cuz chances r that spawn is already fucked before u even get it.

Thanks for the heads up JCM4620.
I did take some samples of the spawn bag and was able to get a nice solid culture that I am planning to convert to a liquid culture. Would you ditch this as well? The culture looks pretty damn clean.
I started with a kit because I wasnt confident starting from spore. I didnt realize how notorious for contamination.
For coffee grounds, are they still able to contaminate despite 3 hours at 15 PSI? I would have thought this would kill anything.
Btw: What is a Trich bomb? Which Big ass blob are you referring to?
Would you wait and see what comes of these before ditching?

Looks like you have a bin full of pubes. There are a few big blob's. I have encountered the yellow liquid many times, but only in jars. Not enough oxygen or high humidity. It never seemed to hurt anything. Keep growing until you get psychedelic colors on the mycelium mat. I too started with a kit, 40 years ago.
