From what you told us it's a lockout due to the high ph and the ph fluctuation. If you flush your medium it could help to reset the ph value and the Ec value of the soil ; my guess here is that she received the right amount of nutrients but she wasn't assimilating it correctly due to the ph and while the issue was settling up it was more difficult for the plant find nutrient in the soil so the nuts start to accumulate. About the fact it's not flowering it is because you have a Photoperiodic "auto" , it happens sometimes and it is due to the genetic , ruderalis are crossed with feminised photoperiodic to have more potent and flavorful plants and sometimes the autos have to be forced to flower by flipping into 12/12 ( recessive Gene's if the photoperiodic used for the cross )
