it could be possible you where heavy/over feeding N during veg
and switched to bloom nutes that are now lower in N
im not sure its just a guess
when was the last time you potted up?
how many days into 12/12 are you?
what type soil?
what type nutes? /how often? / how much?
do you check ph?
how often do you water/ is it possible your over water?
I wouldn't go adding any N
its ok to have mild N def in late bloom (if that's what it is), that's better than too much, and they do look very green despite the yellowing at the bottom so stay away from adding anymore fertilizer for now...just water until you sort it out

It did happen right after I re-potted her. Soil is the same she was in previously, Happy Frog amended with vermiculite, perlite, bat guano, and worm castings.
I've never checked the ph, I haven't switched the lights to 12/12 yet, she just went into flower while under the longer light cycle.
The only thing I've fed my girls is some worm castings and bat guano in the soil, some leachate from my worm inn, some additional bat guano mixed with water, and 1 feeding 1 week ago of fertilizer, Jack's Classic, and I gave the recommended amount for houseplants.
Thanks for your replies.

You sure as hell have done something to kick in flowering. You should switch the lights to 12/12 before you stress them out.

its hard to pin anything down with certainty cuz we don't know why she went into flower
maybe be its a auto
but im going to go with calcium and magnesium def
its nice and green from the EWC and such
the guano was it high P or high N
foxfarm is low in calcium and magnesium from the bag
id add 5mls calmag and 1/2 tsp espsom salt 1x
and then cut back to 3mls calmag 1/4 tsp Epsom salt evry other watering

Thanks for your reply, it wasn't sold as an auto, caramel kush from barneys farm. First time growing this strain. There are 2 other plants of different strains that don't have these issues and they've been treated pretty much the same.
But to answer your question it is high N bat guano. They have only been watered with city water which I thought usually contained calcium.
I also add crushed egg shells to the worm bedding so I think that would be a source of calcium.
I will try your recommendation of cal max and Epsom salts and hope that helps.
Thanks again

magnesium, ide add a bit of cal mag and sprinkle a pinch of some epsom salts on top for good measure.
magnesium is burned up during photosynthesis, you can tell by your purple stems. the plant ran out of magnesium so its killing leaves to be able to keep up with the mag thats currently available.

Do I add the Epsom salts in a solution, so 1/2 tsp : gal water?

your in soil so you can either
add 1/4 to 1/2 tsp to a gallon and let it dissolve and water it in
or you can sprinkle 1/4 to 1/2 tsp on top and water with a gallon of water
1/4 tsp for reg feedings
1/2 tsp for def

next time
if I where you
id use the fox farm ocean forest soil and not bother amending the high N guano..theres already enough N in it
you don't need the perlite or vermiculite but if you want to add it go ahead
egg shells are great and all but it takes a long long time to break down before its available
if your intending to go organic I would amend 2oz gypsum per cubic ft (7.5 gallons) of foxfarm ocean forest soil and water only (with the occasional 1/4 tsp Epsom salt) for roughly 5 or 6 weeks before adding fertilizers

guano is great and all but if not properly used it can cause more trouble than its worth
its very strong and very quick availability and if used requires very little
I only use guano in tea and only if im N def or P def (depending on the guano)
I throw a little extra P in there late bloom maybe
if your not running an organic grow or if your using a well balanced fert I wouldn't bother with guano at all

I may be wrong but I think the egg shells are broken down by the worms. I add crushed egg shells to the worms to give them the grit that they need.

man If I was using fresh worms id not be using liquid fertilizers or salt fertilizers at all if possible
sounds like you talking no till organic which is something different all together that im just learning, for that reason I don't yet give advise on it
but in that case youd be looking at brewing teas and relying on soil amendments and such to build biology
maybe go over to the organic section of the forum and post direct in there
that's where youll find the most help on organics and not till and such
seems like those guys hang out in that section

There are no worms in my soil. I have a small colony of compost worms, they can't survive in soil.
I just use leachate that drains from the worm inn and the castings for fertilizer.
