got cfl lighting in a stealth grow box 3 by 3 by 3 ft long and it started 12/12 3 days ago. how long does it take to show sex also what nutes do i use. i used mirical grow for veg.
Dont use miracle grow. Your plants will show sex within the next few days or maybe it might take another week and a half. It depends on how mature your plants are and if they are flourishing or stressed. Use an organic water soluable nutrient to feed your plant.
