So, I want to add something here. But before I do, I need to ask...is this an auto flower or a photoperiod? Autoflowers don't care about cutting a light schedule. In fact, some growers leave the light on all the time. If you're at 18-6 then leave it. That plant is not big enough yet, and it needs to continue its vegatation stage. If its a photoperiod...meaning that its a regular seed, then you would have to change the light schedule to 12 12 before the plant would flower at all. I suggest reading the difference between the two so you don't screw things up. Trust me...leave the light on for now until you understand what you are seeing.
