Hey, those look like some fully active bud sites to me. I guess when i think of preflower, i think of those very initial wispy hairs that start poking out of the bode space...yours look like they've gone much past that to where there's actual cluster of pistils in the various spots. The only thing I did think about with the diary was when you might remove the "grow" nutrient? I was just curious if the additional N could slow things down at all?
Good luck with the flowering, she definitely well on her way.✌️
