A week later and HxT #4 is still not flowering. I now had a look at my photos from 2012 when I grew Nirvana's Haze at the same place, it started flowering (first pistils on tops) on the 22nd of September. So Ace's Haze x Thai seems to be at least a week slower in flowering initiation compared to the dutch Haze.
Anyways, it seems to be in good health, despite having several of its lowers horizontal branches broken by a recent storm:
