Been a haze lover for many years myself, with ssh at the top of the list. Which seed co did you get them from? Mr. Nice has the true ssh, not that there isn't other great versions out there, just his is the real thing. The breeders from out that way tend to list their finish times based on the onset of flowers, not the change over to 12/12, so I always add about 2 weeks for that to the time, and another week just cause things always like to run longer than advertised, most of the time I find anyway. But ya, watch for them to look like they are maturing, and then take another bump in growth, some will even do that again, but it doesn't look like you have any heavy nevils phenos so I doubt you need to worry about that. Most of the time its at least 12 weeks with this one, but some phenos can go to about 16
