Photo flowering on 18/6!?

I'm 11ish weeks into what seems to be a solid grow with (fingers crossed) no major malfunctions so far. I'm running a 4x3 tent with 1x Auto Northern Lights, 1x Auto Great White Shark, and 2x I49 CBD. As it turns out, this is far too many plants for a tent of this size...... but oh well, lesson learned. This is my 2nd grow cycle. Last one was fine with 4 plants in this space. These girls are much larger.

The autos didn't start to flower until week 8 which I didn't think all too much of until I realized how small the buds are at week 11. I've done a little research and have found that it's not abnormal to have autos run long. I had a few minor glitches at the start of the grow which likely caused this, so I'm not worried about it. I expect them to run 17-19 weeks. They look REALLY solid with lots of colas and nice tightly stacked bud sites. Fingers crossed for some big solid donkey buds!

Anyways.... on to my actual question. My light cycle has been 18/6 for the whole time. I do spend a fair amount of time out of town, but I'm quite certain that there have been no light malfunctions as I have a camera in the tent and check it every so often to monitor humidity and temp. The autos have been in flower for about 3 or 4 weeks. Just the other day I noticed pistils on one of the Photo period I49 CBD, but not the other. She is definitely coming into flower. I cannot for the life of me figure out why. Flowers certainly appear to be female, so I don't think she's gone hermaphrodite.

Any ideas as to how this happened? Anything that I need to be doing or watching out for?

Now... part 2 of this question... I'm debating switching the whole tent over to 12/12 and put the photos into flower. My priority on this grow is to ensure that the 2 autos get as much as they need to have a good solid yield. I'm not worried about how long they take. My initial intention was to run the tent on 18/6 until the autos were ready to harvest and then kill the lights for 48 hours to a) get the autos ready for harvest and b) switch the photos into flower and start the lights back up on 12/12. As I'm thinking of switching to 12/12 roughly 6 weeks before the autos are done, I'm now wondering how detrimental it will be to the autos to switch them to 12/12 at this stage.

Any thoughts and ideas would be greatly appreciated! Thanks all!

As I'm sure these questions will come up:
1x 1000w blurple per plant with a full spectrum t5ho running down the center of the 4 plants.
Temp has been pretty steady through the grow at ~25C/77F during the lights on, down to 15C/59F lights off
Humidity was running pretty steady between 60-70% during auto veg, now that they are flowering it's down to 40-50%
- Could the drop in humidity have caused the one photo to switch somehow? I don't think so...?
I'm using amended organic soil with compost, worm castings, bat guano, dolomite lime and a splash of 4-4-4 mixed in.
Nutes have been roughly 600-700ppm during veg, more like 1200-1300 during flower (for the autos)
pH in and out has been solid at around 6.3 to 6.5

Crazy i came across this thread immediately, I'm experiencing the same issue with my photos. I just noticed big ass pistols coming out of my blue dream plants while still on a 18/6 cycle.

Woo hoo! I'm not the only one! Hahaha!

Any theories? The best one that my buddies and I have come up with is that maybe because the autos are in full flower they are influencing the photos to follow suit.
 
It does look like it's trying to flower. That's a new one to me, but I do 24/0 for veg. Probably the strain, but that's just a guess.
Well... I considered that, but only one of the 2 photos are doing it and they were both sold to me as the same type - I49 CBD. Worth mentioning is that there is a 3rd of the same type in a friend's tent and it is still veging on 18/6 and was germed at the same time. Admittedly, it was the weakest of the 3 hence it being donated when I ran out of room.

Well I ordered mine and the only theory I have is that they mistakenly sent me autos.

There can be lots of different phenotypes that come from the same batch of seeds. My theory is genetics.

My theory is you have ruderalis genetics mixed into your photoperiods. I've had it happen to me and I killed them. But since you are growing autos maybe let them finish.
