Monotubs pinning issues

Hi guys! I have a problem with a few monotubs I'm currently running. One is not fruiting after almost 20 days since spawn. Two are fruiting badly, only near the liner. What do you think? Bad FAE? Side pinning? I'm considering in flipping the substrate upside down to see the situation and attemp eventually a bottom fruiting but I'd like to know your opinion before doing anything. Top holes are without polyfill but I live in a humid environment and I guess it's better this way. FAE seems ok, judging from dryspots... At day 12 or 13 I guess I've discovered that all monotubs have collected a lot of water under the liner, maybe this can help...
In the last picture you can see there are a few knots and some pins also in the middle of the substrate, but things are miserable also in this case...

I read a thread recently on here with similar issues (I'm also having the same) and they increased the FAE to get surface evaporation to increase, try that maybe

I already tried to leave the lid off for a few hours but I noticed a few spots with bruising mycelium even before all surface water evaporated. Can you link me that post please?

I may be off here, but i thought bruising was from direct contact with water etc, or extreme dryness of the substrate. I'll drag it up for you =)

Is it drying up? Is there still good condensation on the walls with decent humidity? That looks like some thick ass myc. Lol.

I left tubs opened for a few hours and this time this seems to work. At least for the best mono, now it's covered in knots and a few pins in the center. It bruised a bit but it's not really an issue I guess. I'm considering the idea of picking the biggest pins to get a more even pinset. I would appreciate a suggestion from an experienced user on this topic

I just pick them as they mature. I don't think you're goin to get an even Pinset unless you clone, and set the conditions.

Good to hear, a mate loosened and tightened his polyfill until it maintained humidity at minimal airflow, misted a bit and now cranking fanning to evap the surface. hopefully it works too haha

20 days since spawning isn't that long....
is your polyfill stuffed in super tight?

Yeah just be patient, looks good to me. The substrate looks a little dry. I have been told the biggest pinning trigger is evaporation at substrate level, so maybe a light misting just to cover the surface with moisture will help you. To maintain humidity levels you may benefit from a very small amount of polyfil in the top two holes.
Also what variety are you growing? How did you prepare your substrate? Could you show a pic of the entire fruiting chamber from the outside?
Here is a pic of a tub I did awhile back at day 10 into colonization, you can see a lot more moisture on the surface:

This image is 9 days after the picture taken above (9 days into fruiting conditions), you can see I dried the sub out a bit:

Here RH is +70%, and I usually have more troubles with polyfil in top holes. I'm currently out of it also, so this time I'll just take an eye to lightly mist in case substrate dries too much...

losen it up a bit. Fresh air is a pinning trigger. Look up How Frank Does Monotubs for info on how to dial it in

I loosened it a bit after noticing that the "biggest" pinset is in the monotub with super tight poly, and in any case the vast majority of them where near bottom holes. So, I suspect there was stagnant air and too little FAE at substrate level. Now I used the remaining poly for top holes, to help with humidity... Let's see!

I had the same issue with this one op

Happened everytime I tried dunking my grain spawn....it was the oddest thing since the others did well.... I attributed it to bacteria retained during the dunk.... not 100% sure what is up with yours.
