Yet another Q bout blue cakes

Here's the setup...PF tek, BRF/Verm, RR style FC(4 inches of well soaked/drained perlite), 2 strains:PR and B+--temps 68-76.
History: This is the 2nd grow. Had fairly good success with 1st in very similar FC when only doing B+. Decided to do new FC because too many holes in 1st and a couple of cracks/duct tape(thought we could perfect this method)PRs birthed at 5 weeks(have read that they can be slow) B+ birthed at 3 weeks--after we started seeing pins begin to form at dry verm barrier.--Not ideal? PRs have been in FC for 9 days with a small amount of weird mycelial growth--the weird growth seems to have slowed and about 4 days ago started noticing bluing--dark blue around the tops. And no, this is not where the cakes were handled. Do not suspect contam as it has not spread quickly and they upheld the H202/Qtip test.
B+(the 1st 3 cakes) have been in FC for 5 days. Only one cake has 2 shrooms growing from it--and that is the one that started turning blue 2 days ago--a much more even and lighter blue than the PRs.--once again--do not suspect contam or bruising from handling.
I know that cakes blue due to some kind of stress. As I understand it, it is virtually impossible to have too much humidity unless there is standing water which there is not. This brings me of course to low RH or low FAE.---The cakes do not feel dehydrated to me. They have much more weight to them than during our 1st grow throughout the flushes. For the first few days they did not get much FAE because we thought our small sizes on 1st grow were due to low RH. Past few days we have upped the fanning to 4-12 times per day. Unfortunately some days they go 13 hours without fanning because of work schedule. (And yes we are using a P.O.S. digital hydrometer now because that is all we have, but will purchase an analog next week.) But this is the same POS we used on first grow. This time it is telling us our humidity is staying consistently higher than on our 1st grow. We are misting every time we fan because we do not trust the hydrometer. There are some holes in bottom of FC and FC is elevated only about 2 inches. There are maybe 80 7/32"(one step smaller than 1/4") holes in a 124 quart FC. We do have AC running and a ceiling fan. I was thinking the ceiling fan would help contribute to FAE, but maybe I am wrong? I guess the questions after all of this rambling are: Do we need more holes in FC to up FAE? Do we need more humidity? Do we need to fan more or less? Should we keep the ceiling fan off? Should we raise the FC to improve flow through the bottom? Sorry for the extremely long post--just trying to stop alot of questions in their tracks. Will post pics as soon as other 1/2 gets home and shows me how. Thank you to this whole community!

usually bruising (without handling) is caused by the cake being dry

Or also direct misting can cause bruising as well.

As already said, blueing is from the cake being to dry, try dunking it. I havnt even reached my first flush yet but thats my experiance with blueing of the cakes that dosnt involve handling.

Thanks for th replies. Triptheory2004 That could be what's going on. They get misted semi-frequently. When they do I try to keep the mister(?) at a high angle over the FC, however they get misted almost as frequently as they get fanned.
First to be birthed were the 3 PR. Followed by the 3 B+ to the far right, as described. 5 days later we birthed the 3 B+ in the middle. We ran out of vermiculite that day too
