Possible Contamination

Hello everyone!
I recently got interested in psychedelic mushrooms and I've been lurking around these forums a lot. Plenty of useful information.
I got my first growing kit (already colonized) of the Koh Samui strain about a month ago and it's already on the third flush.
The thing is that yesterday I looked by chance at the bottom of the cake and noticed a considerably big yellow spot (picture attached). I don't know how much time it has been there, nor if it was already there when I harvested the second flush but it's bugging me.
From what I've read in the forums, "not white, not good", but at some point I also read that as long as the mushies look ok, they are fine to eat, so since I am pretty much a noob in this world I'd like to ask if any of you could shed some light on this. The rest of the cake (top and sides) looks fine though, so could I pick the mushrooms when they are ready? Or should I trash the whole thing right away?

Metabolites, which is myc piss. Also, any fruits that grow from a contaminated substrate are safe to eat unless the mushroom itself has mold or whatever on it. Could be fighting off contams or you have the temp too high. Room temp is perfect for fruiting.
Next time just do pf tek or wbs/bulk. Grow kits are a waste.

Thanks! Actually I've been applying heat to the bottom of the cake on a regular basis since the very beginning; could be it.
Grow kits are not that bad for newbies who just want to "open the lid and fruit", but turns out that I'm finding this world quite fascinating so I'll definitely try something more elaborated in the future.

Looks like a bacterial contam IMO.

Ugh.. bad news. Is there a way to know for sure? Smell or something..
Also, isn't it weird to get a contam at the bottom rather than on the surface which is more exposed? (maybe from a previous dunking..)
Anyway, I'll probably harvest this flush and after that I'll just keep the grow kit to see how the thing develops. If it is actually a contamination i believe that at some point it should reach the top of the cake.

If its bacterial, which it might well be, then it'll be growing in the place with the best conditions for them i.e moist and warm. You might be able to smell slightly sweet or vinegar.
After you harvest you could give the substrate a good wash in clean water and clean the tub and see if that helps keep it a bay for long enough to fruit. If it turns to mold you'll need to trash it though

-UPDATE-
Harvested batch (not many cubes but they look ok).

This is the bottom of the cake right now. To me it looks like the yellowish spot is less intense in color but has somewhat spread.

Looks there is some bacteria going on, but you may well get some more if you give it a dunk for a few hours

yeah, even if you used MS you should be pulling way more shrooms off that thing, the yeilds are lower when myc is putting its energy into fighting off contams.

So how exactly does trich get a foothold in a monotub? Assuming you put in some clean spawns is it just a matter of keeping the tub closed off till it colonizes the coir or can it still attack a colonized tub cake?

If you have clean spawn, you already won like 80% of the battle against contams. The rest is just making sure your substrate is properly prepped and not over or under field capacity. Then close up the tub and wait for full colonization.

Mondo cool! And just to clarify, field capacity is just a fancy way of saying how much water is in the sub?

Yea, when you squeeze the mix, a thin stream of water should flow down from your clenched fist. If you squeeze harder, then only a couple of water droplets should escape. RR demonstrates it well in this video. (Skip to the 5:00 minute mark)
