Maybe a dose of folier N? I know they are flowering, but this seems urgent.
Do it now!
i
am organics !
i am 100% its a N def showing and the PK an micro nutes are probably def. too.
i go through this all the time with organics.
first off mycorrizea does not buffer the soil. it attaches to the roots , so the roots actually stretch farther lookin for food.
In your case all the food is gone so they need more.
As much of an organic freak i am , i would still recommend using a dose of instant food to fix this prob, cause by the time your food (blood , guano, tea, whatever) breaks down in the dirt an starts getting eatin ALL your bigger leaves will be gone.
She is still reachin for the sun so she is READY for some food.
The reason behind this mess could be
many things.
The reason for such a big change would most likely be in your soil with the microbes (all of them , not just mycorrizae) some of your pots are full of bacteria activity and some of them aint. the more alive your soil is the more food they can process for your plant.
usually all the pots in the room will have close to the same results , but there is always that one that has a lot more/less bacteria activity.
When its hot in there , it causes the top 3/4 of dirt to dry out quicker then the bottom 1/4 an that itself can cause a big change in the bacteria activity in the soil.
So even if you got plenty of food in the soil , if the soil cant process it all then you will become deficient.
I think in your case , your soil is healthy and there just aint no food left in their to feed the microbes.
The only instant fix would be to go get some instant food. it dont matter if its MG 24-8-16 or advanced nutes with perfect "pot" numbers. in your situation its all the same.
Give her one or two full doses of "hydro food" (instant food , already chelated) then start back with your organics , and add a tiny bit of carbs (molasses) to help keep your microbes healthy. then by the time the instant food wears off the microbes will be creating new food for your girl an she will probably need full feedings the rest of her life too.
this is derived from more then an opinion. this it whats going on with your girl.
