 What's wrong with my oyster pf tek jars?

The only things I can think of that haven't been ruled out are:
Bad oyster spore syringes.
Bad ingredient choice.
Not enough time has passed to see growth in second set of jars.
Not enough time for the jars to cool off.
Unknown pressure/temp in pressure cooker.
Needle not long enough. Maybe I injected into the verm filter?
Spore syringes came from a sponsor.
But, how should I proceed?
I could make liquid culture in an attempt to prove the syringes are bad. Perhaps they'd give me a refund or replacement if I could prove it's not me.
I could buy some rye grains?
I could dump the 1st jars out, buy another bag of brown rice flour, and use more spores.
Or you decide something different.
Current jar location:
4 day jar:
13 day jar:
ignore mineral stains
One of the unused syringes:
Also, if you have an answer to this question. That would be great!

What do you mean you filled the pressure cooker (PC) with water? The BRF jars should be placed in the PC and filled with water until it barely touches the bottom of the jars. Does your PC have a gauge on top? If so, then the jars should be cooked at 15 PSI for 60 minutes, then allowed to cool all the way. Then you can inoculate the jars and store them in a dark place that stays 80-82 degrees. Leave the foil on the jars until they are about 50% colonized.

This is my simple religion. There is no need for temples; no need for complicated philosophy. Our own brain, our own heart is our temple; the philosophy is kindness.
There's a part of every living thing that wants to become itself: the tadpole into the frog, the chrysalis into the butterfly, a damaged human being into a whole one. That is spirituality.

Found a better source than answerbag. The necrosis of the epidermal layer starts when the temperature of the epidermal cells reaches 111.2°F; this constitutes the threshold of pain. If there was mycelium inside, it's dead, but if there were any spores left (unsprouted?) they are still alive.

I hope the first lot is just stalled. Heating pads don't heat uniformly so the ones around the outside edge were much lower temp than the ones in the middle which were quite warm to the touch.

I fill the PC with water until until it barely touches the bottom of the jars. I have no pressure gauge, just a weight like this on top. The jars are not in a dark place and are being kept at 75 F as seen in the picture in my first post. No aluminum on top.

Pressured cooked the jars for 90 minutes using the old style pressure cooker with a weight on top. Cooked at high, turned down to low, then turned back up to high. My Dad cans vegetables and the pft pft sound just didn't sound normal to me unless it was on high.
You're supposed to turn the PC down to just under the temp that makes the weight move.
If you used it like a straight pressure canner you probably dried your cakes out.
What can I do about that? Can I squirt sterile water into the jars?
