Those are my first casing experiment.
At the right, I used vermiculite and brown rice flour and made cake. Then i break into pieces with my hand. In aluminium tray , I put perlite at bottom, cake pieces in middle and casing layer to top.

A perlite layer on the bottom is considered useless and often harmful since it doesn't contain nutrients it can harbor contams that can't be seen until too late. Read around thats the general consensus.

Humidity sounds good, so long as hygrometer is working correctly. You can tell by the amount of water vapors or droplets on the sides of your FC. Water vapors will begin to form on the sides on the FC at 99%+.
Make sure fresh air exchange is good, and
make sure they're getting approx. 12on/12off of good light.

Those are the first things I would check.

When you crumble or spawn to bulk you need to give it 7-10 days to recover from the trauma.

That left pic looks very odd, that growth doesn't look right but you didn't mention what species you're growing.  If those are cubensis I'd be worried.

I cant believe people are still spreading that myth that humidity can be gauged by water droplets on the walls, which is complelty untrue. You cannot judge humidity by eye. it was even disproved by someone posting a monotub and asking what the rh was based on all the water droplets. There was a lot on condensation on the walls. What was the rh, it was 86 i think.

Condensation on teh walls, indicate a temperature difference between the inside and the outside, when its warmer on the inside than the outside, the walls of the fruiting chamber will be cooling, which will condense water out of the air.

The the OP, you shouldnt use anything in the bottom of your trays.  When you fruit cakes as cakes, you dont sit them directly on the perlite, why you you do it in trays?? a bottom layer will encourage pinning where you cant tend to it. Neither perlite or vermiculatie should be used.

Those casing layers look very odd. The one on the left looks ok, except part of it looks like cobweb, the one on the right just looks plain nasty and the mushroom thats growing just doesnt look too healthy.

is that 50/50+ - peat/verm/lime??? and did you pasturise it. I hope it wasnt sterilised

Information about the hýhumadity helps me to better understand. But I also use hydrometer. It says humidity is %95 in FC.

I used perlite at the bottom as water reservoir. I used it because , I start cultivating from a grow kit which I bought from Amsterdam and the kit had bottom layer. I decided to use as well...but will never used again...

I was thinking the right one is the healthy one.

After 3-4 days in FC, i realized that I put casing layer very tight. With a sterile tool, I dig the surface of the layer a little bit to obtain fresh air better. That is why it looks plain nasty.

I put some new pictures of the mushrooms and expecting an explanation what symptoms considered that they are not healthy.



Cobweb, I am not clear about that. Cobweb is the big white solid thing or smtg else ?
And there is another picture shows a little pinhead ( the only I have on that casing ) ...


For casing layer preparation, ý used Poul Statements recipe. 10 part Vermiculite, 10 part peat moss, 1 part gypsum, 1 part calcium carbonate. And I pasteurize it , not sterilized.

It's hard to tell without knowing every step you did, but bluing is very often a lack of moisture. My friend can tell if his cakes are bluing by dehydration or bluing by contam by picking it up and comparing it to ones that aren't bluing. It should feel noticeably lighter in weight, if it is lacking moisture.
