Pre 12/12 Dark Period and Nutrients

I was planning on giving my plants 72 hours of dark before switching to 12/12... I was wondering if I should go ahead and switch over to my bloom nutes or stay with the veg nutes during this dark time?

I see no reason two do this the plant will adjust to the light change itself no need to shock it into submission.

I must agree with Bryon. She is a plant and a female so just switch her lights to 12/12, and the rest is up to her hormones and genetics.

when switching to flowering, give it 24 hour darkness before switching to 12/12. No need to make the process longer.

even sure about 24 hour dark before going 12/12?
