You are using a 1.000 watts led light right? Is that the true power draw or more like a 1.000 equivalent?
Second, you have a 3 x 3 tent, but you only are growing 1 plant. You need to fill all the grow area that your light covers to get the most of it, in the case of autos, as a rule of thumb plant 1 seed per sq ft, in a 3 x 3 = 9 sq ft, you would need 9 auto seeds.
If you want to grow only 1 or 2 plants, then I suggest a female photoperiod seed and veg a couple of months in order to really fill the canopy before switching to 12/12.
