i am growing 6 afgani and 3 skunks haze, and i started to think i ll get troubles cuz there are differents flower times....anyway i ll not veg more than 5 weeks, i wont a 2 meter height plant, AND i noticed that the skunk grow more tall than the afgani.. so i am in trouble at this point i ll have to top cut them, or the afgani x 6 will get less light
