Success until fruiting

First time grower. On the 27th of July I spawned 5qts to bulk, following Bod's guides, and I tried a mono tub. The first 3-4 days there was obvious growth, then it slowed. August 2nd the humidity started to disappear from the sides of the tub, so I started misting. 2 or 4 sprays twice a day. One day of heavy misting today.
Where I live it has been abnormally hot, and my AC doesn't work as well as needed. So I wouldn't be surprised if the room got to 80+.
Anyways, came home from work and noticed dry tub sides again and that sweet earthy smell was gone. I smelled it last night before bad. I heavy misted (12 sprays) and about 30 minutes later while helicoptering I noticed the tinest of tiny pins.
Can you help identify where I went wrong?
Grains 6 days before spawn to bulk(looked thicker day of):

I suggest adding a casing layer next time. A casing layer is just a layer of hydrated coco coir/verm that covers your grain and allow it to retain moisture. A casing layer also protects from contamination imo. Looks like you can allow it to continue to fruit, I don't see any mold and it doesn't look bacterial to me at the moment.

There is no humidity on the sides of your tubes that's just condensation, it just shows your tub was being warmed by the mycelium eating its food so that temp difference causes the walls to condensate , if your temp in your room catches up though then your walls stay dry.

  It doesn't matter what i think of you...all that matters is clean spawn I'm tired do me a favor

Definitely is drying out. Substrate cracked overnight. I'll do the casing layer like you suggested.
Would you suggest that I put the lid on the next mono tub the correct way when it is this hot, and open it up every day/drill a couple holes?
I'm 95% sure I had field capacity correct. There were times I came into the house and my downstairs thermostat was reading 78+, so to try and cool off this room and the house I turned on the attic fan and cracked a window. My guess is that 80+ degrees and too much airflow caused the substrate to dry out.

What is your FAE like? Is this an unmodified mono or FAE style with holes? I read BODs TEK so I am assuming unmodified.
Firstly, I prefer to NOT have any grains exposed, so layering or a casing layer (as previously recommended) is a good idea.
That doesnt solve your moisture issues however. Drying out in an unmod may mean that you were well under field capacity. If done correctly, you should not have to mist it for a couple of weeks and sometimes all the way to first flush.
Try Pastys EZDial - drill 1/4" holes on the long side about 1-1.5" above the sub line and holes high on the short side under the handles. Mine are 26qt with 3 holes long side and 5 holes short side.
This tek is new to me but working very well.

You need to get a way of knowing the exact temp in the room you're cultivating in. You need 73-77f for colonization and fruiting, however an unmodified tub needs precise ambient temperature control so try to keep your room within the 73-77f range. High heat environments dry out tubs quickly, modified and unmodified alike: water evaporates. Do not remove the lid, modify a monotub to allow FAE while retaining moisture, polyfil or even just one layer of micropore tape will benefit you in covering the holes, micropore tape I find retains moisture better than polyfil, fyi I live in a desert and its 101f outside rn.

 I would definitely follow this advice. If you want some ideas on monotubs I'll post up pics of mine, I have tampered with differing hole size, placement, and more. I would measure just slightly over field capacity by just half a quart extra when making your substrate. I use one brick of coir/verm with boiling 1gal 1qt of water in a bucket which I then cover and allow to reach room temp before spawning. Some folks dont boil but I suggest it as it does help in preventing contams.

I agree with you. To be honest, I thought I had too much water in my coir. When I squeezed it wasn't a couple drops/small stream. It was a small stream to almost a squirt of water. I left it like that because of the heat.
And yes, it is just an upside down lid. I can see an airgap all the way around the upside-down lid.
EDIT:
I'd love to see what you use in the desert. I am in a desert, but not what most people think of when they think of the desert. I also boil in an insulated container. I will add more water next time as well.

An unmodified tub if done correctly will yield quite the weight.
 I have noticed however that with unmodified tubs the ambient temp of the surrounding environment must be kept between 73-77f. On the lower end 69-72f you'll see too much moisture retention causing stunted growth. On the higher end 79-83f you'll find your substrate dry and again stunted.
Modified tubs I find easier to dial in.  This tub is a basic SGFC that i've left the bottom in tact so it can double as a monotub.
Here you can see I'm using a combination of Polyfil/Micropore tape to achieve proper FAE and moisture retention.
  This is my basic monotub setup, it provides adequate FAE and the option of easily increasing or lowering the FAE.
 This is currently on-going, I am using one layer of micropore tape on this B+ tub. This tub is 1 brick coco coir, 2qts verm and 1.2gal of boiling water left to drop to room temp before spawning. Within the utah, nevada, arizona area we all know how hot it can get, this is why I fill over capacity as substrates will dry out quickly during these hot months.

That's awesome. Thank you!
As I inspect more I'm seeing almost 100% side pins. I'm going to use a liner in the future. I'm going to let it grow, but do you have any suggestions on how to approach this last week?
By EOD today(its a hobby right?) I'll have a total of 42 qt jars, and a 5qt bucket colonizing. I figure I just have to try to get it right again, and again, and again until I say, "Oh fuck...I have waaay to many." I'll modifying the tubs tonight while I'm at it.

I am not totally convinced that blacking out or using a liner will stop side pinning. Light is secondary to surface conditions and FAE. The side pins are likely caused from creating a micro-climate in those areas.

So then the real answer is keep my substrate moisturized properly, and pack it down it bit more?
One day the answer will be something other than: Do it the same, but only better next time.

I have found that liners actually do aid in preventing side pinning if you tamp your substrate down properly. Every time I've gone without a liner I have had major side and even bottom pinning. They're useful for clean up and rehydration as well as with harvesting because I leave enough of the liner to grasp and retrieve the myc.

Especially the "outer ring" i slightly tamp down more, and pull the liner a bit away from the walls. Great with a double layer liner, one sticks to the condensated walls, the other to the cake. You can easily get heavy condensation, so it`s just running down the tub, to be poured out at harvest.
So yes, to me it`s the best choice to prevent side/bottom pins. Your surface may be perfect, but the sides may be a bit better due to that heavy condensation sometimes.

Something’s off with that tub I think, it hasn’t colonized at all on the surface but it’s pinning already.
Could be from the heat, if I let my room go above the low 80s weird stuff starts to happen.
I’m in a desert too, usually around 12% rh and unmodded tubs work great. Tiny adjustments with fae make huge differences though.
