Oyster Mushrooms - Stunted Grow in Martha Tent

Hello,
I recently built my first Martha tent, but I'm having issues with fruiting pink oyster mushrooms. The caps are very stunted and they turn white. My assumption is that they aren't getting enough FAE. However, I don't have anything pumping the CO2 out of the tent, instead, it releases from the openings at the bottom. I'm not sure if that could be the issue. Lastly, the tent is made of the green clear plastic, I'm not sure if that could be preventing an adequate amount of light in. There is a large window in my grow room, so I'm using ambient light.

The automation for my tent runs every two hours and I've been able to maintain around 97-98% humidity. The setup consists of a home dept bucket, 3 head pond fogger, with a 4in duct fan blowing fresh air into the bucket. A 1 1/2 PVC pipe pumps the fog into the tent and it branches off for each shelf. There are two fans inside the tent that run 24/7, but they are very weak and are used to circulate the air. Basically they help to push the CO2 to the bottom.

Other mushrooms are growing just fine, but the oysters are having trouble. Any ideas of what I'm doing wrong?
Thanks in advanced!

Need MORE fresh air.. You need an exhaust pulling all the Air out. Moving air inside the chamber won't cut it as sufficient. As you are clearly seeing. You also need to pull the air out.
This used to be my martha with my door open to take pics of the oysters. But I had my intake at the top and exhaust at the bottom. It is best if you make your martha air tight so your humidity doesn't leak into the room and cause mold on the walls... .. .

Thanks for the advice!
Any recommendations for the setup of the exhaust and how often it should run? I was thinking about using an 80mm USB fan connected to a filtered PVC pipe at the bottom of my tent and running it for 5 minutes after the fogger runs its cycle (every 2 hours).
Would pumping fresh air in every hour for 5 minutes be sufficient or would it need more?

Exhaust should be on 24/7. You will get much better consistent results. I used and still use a 4" $50 inline exhaust fan which is piped directly outside. I had cut out a piece of insulation board foam to stick in the window and cut a hole in that. I had just turned it down lower but not lowest for my martha.

Thanks again! I'm going to have to think about this. Pumping it outside isn't an option as the winters are rough here.
I think I'm going to buy this fan for the exhaust: VIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan (amazon)
Then have it connected to this filter pumping the exhaust into my room: Vanleno 4inch Carbon Filter (amazon)

The spores will clog that filter up in short time. If you put a 1" or 2" solid foam board in the place of part of the window it will solve your heat and cooling issue. Think how thin that window is....

Thanks for the tip. I'll have to think about this. May have to move things around to make this work.

You have really nice fruits here. Just a quick question - when slicing bags, do you slice only bag or do you cut knife through substrate (so you slice substrate too)? Also, when they start pinning? I have 3015 strain 5 days in FC and no pinning yet.

Why thank you. That pic wasn't of 3015 strain. Not sure what it was, but my weight wasn't as good as 3015. Although I do have 3015 now. I do cut into the substrate too when slicing the bags. I do not touch them when they start pinning. No. I just keep the humidity up. I have 1 day of the week I put grain into sub bags for my bags to sit on the shelf for 2 weeks and take the bags that have been sitting for two weeks put them into fruiting chamber and slice the bags. It's also my thorough cleaning day. Very busy day for me.. very early start.
These are not pics of my best of the best but so you get an idea: Here is a pic of 3015 after the edges start to curl up
Here is a side by side of 3015 2 different clusters set to fruiting the same day. I will need to move my bags a little farther from the wood and not make the slice so far to be closer to the wood side either, thus why the one won't get picked and sold.(so yes I did notice. I have been experimenting with slice size and shapes). The closest one hasn't had the edges starting to curl up yet, the farther ones has. So you can see the difference. Tomorrow the closest one will look more like the farther one and the other pic. 
I have people more and more one after the other coming up to me RAVING about my mushrooms. Often times in front of customers I am trying to sell. "They taste better than anything they can find local such as through Wholefoods. They look better. Night and day better too. OMG I bought them last week they are sooo Awesome." Stuff like that. As I told the one lady last week, I pick the best for Market and let other people have 2nd and 3rd best. But Farmers Market gets the best. They are paying the premium price after all. Also, before I forget the point I wanted to make before I got on my little happy brag box. Those 2 pics are 1.5 weeks after putting into fruiting and slicing the bags. If I let them stay 2 weeks they would be sporing all over the place more likely and curled up and looking sad, except for the stragglers.
