Flower food, or hurry up and wait another week?

Hello- I, personally, would start tapering off on the veg nutrients. Your plants appear dark in color to me and show the possibility of a little nitrogen toxicity. Perhaps next week you can start tapering in flower nutrient amendments. Then after two weeks you'd be on primarily flower nutes. With the visible pre-flowers, she's getting ready for the switch. I say this primarily because the nutes I'm using now seem to be added to some degree just prior to flower. But I still haven't found the ideal balance. I don't see what nutes you are using on the diary.
