First grow attempt, RH or FAE off?

This is my first mushroom grow attempt. I used PF Tek to make 10 jars of P. Pulmonarius (Phoenix Oyster). The cake inoculation went perfectly & without any signs of contamination. I birthed them into a SGFC (1/4" holes, spaced 2" apart on all 6 sides) with a damp perlite base. The SGFC is elevated over the table top using empty 1/2 pint jars, so that there should be enough air flow below it.
I've been misting the cakes about 3 times a day and keeping a light on in the room about 12 hrs a day. The weather has been hot (85° F / 30C) for the past week. I'm into day 8 post birthing.
Here's the problem: I've been seeing a dense, white cotton-candy like growth forming at the base of several cakes, and spreading onto the perlite. It is not poofing up like cobweb mold is supposed to nor is it exploding out rapidly. Is this just myc?
Second, the small fruits look like they are growing their own pins.
From what I've been reading here on shroomery, I'm guessing the RH is too high and the FAE is insufficient.
So - it that accurate? And if so - how can I fix it for this flush and into the next flush? Pix are attached.

They look very dry to me, and are growing to water at the base. It appears the fruit bodys contain the most water.
The temperature has dried out the sub. Perlite will not be sufficient.
----
You can try a rescue, use very clean water and dunk for 24 hours. Re-roll and purchase a hygrometer to check RH%.
----
You can allow the myc to grow on the perlite. In your case you will benefit.
----
Your container walls should be wet.

Otherwise it is too dry.

Thank you for that suggestion! I was thinking the RH was too high and have limited misting for past two days so as not to make things worse... and instead I probably have!
It makes sense that the higher than normal temps have dried this out.
When you talk about a rescue, does that mean stripping off & discarding the already grown pins and mushrooms? or just carefully dunking the cakes intact, rerolling in verm (which would now be coating the existing mushrooms)?
I can use boiled/then cooled water for the dunk, that should be clean enough. I will also get a hygrometer because that would have tipped me off right away so I can see the benefit of it. (Actually I might use one that's in an musical instrument case I have!)

Yea oysters dont do well in a shotgun. Maybe pinks but not many others. You need active fae and high RH. Try hooking up a cool mist to feed it.

Thats up to you, I would remove them, dunk, re-roll.

So here's my update on the oyster mushroom grow. Please remember this is my first attempt growing any kind of mushrooms & so I'm not sure what's normal & what's whacky.
- On 7/20/16 (10 days ago) I cut off all the deformed pins & malformed fruits off all the cakes. I rinsed off all the loose verm I could, and dunked them in cool water for 24 hours.
- The next day I rebirthed them: rolled them in dry verm and set them into the SGFC. This is technically the 2nd flush but I used all new perlite and a new SGFC.
- I've attempted to mist more frequently and using more water this time, to avoid the drying issue. I'm fanning & misting 5-6 x a day. Average room temp is about 80-85°F in the past week.
Overall more mushrooms seem to be forming, but a number have dried already, and a another small number are growing small primordia atop them, in a kind of fractal arrangement. This was happening before too.
Am I still not giving enough water via misting? Not fanning enough?
Pics are here.

Fanning and misting will never work for oysters, you need active FAE meaning a fan with some sort (s) of added humidity. Ultrasonic disks in a bucket with a float valve is a good start for less than $40.

I have never seen that happen with oysters before.
Take the lid off, as said a sgfc is no good for oysters. While they lack tolerance for high co2 they will fruit quite happily in an open room with no additional humidity though obviously it's less than optimal.
BRF cakes are really not the way to go about doing oysters. They will dry out really fast and it's a hell of a lot of work for what will essentially be breakfast for 2 people at most. I would grab a bag of chopped straw then pasteurize and crumble your cakes into it. Getting 1000% more yield than the cakes alone is quite realistic.

Well good second attempt, and well done with the rescue, everything looks clean. Shame about the conditions not meeting requirments, 5 stars for the try.
Now you know what the issues are hopefully you can fix them.

Why is it that the BRF cakes dry out so easily?
Irkles, I grow oysters in bags of sawdust and wood hips and just grow them in my living room, room and even my kitchen . I always thought that the bags kept them humid. After you dunk them try putting one of them in a bag and tightly around it so there's no extra space in the bag and just poke a hole about the size of a pencil and just leave it anywhere in your house. Maybe it will work even if BRF dries out quicker.

Surface area to volume ratio, they are small so dry out fast.

Thanks for that tip! For now I've crumbled the cakes up and mixed them with some used espresso coffee grounds I got from a local coffee shop. Put this mixture in a couple of 2-quart jugs and left the lid slightly open.
The myc is growing like *crazy* into the coffee grounds. I'm thinking I should wait until I can almost *not* see the dark grounds anymore, then open the lid up all the way and set it in direct sunlight. Maybe that would be enough to trigger pinning at that time?

Please read a lot more. Your way off with a few of your methods. They do not need much sunlight at all

Sunlight is for vitamin D, direct sunlight will dry out and possibly damage your mycelium. As Gr0wer said they don't need much light, near a window is enough, indirectly.
Temperature, FAE and humidity is more important.
