It's the moment! 😍, I washed roots with water 10lt with pH 6.5 each pot, each one was two days in darkness, the missing clone and the longest plant, they still have a week and something else to wait.
Happy of the results! tricomas by heaps and a very attractive citrus smell👌
I just think its signs from your HST and the transplant to the bigger pots.
And if you haven't flushed her sometime under the veg its time to do it now.
I dont think it something to worrie about but i would keep an eye on it.
Good luck.
