help with growing first timer

iv bascially grew my plant blind haha dont know anyting about anything but i have it to the last stage flowering tha room is completley dark during the night time and i have it on 12 hrs light and 12 off i have a heater in the room andi have a fan blowing out all the air in the room out the bottom leaves are ike dying but that just be becausei hade a black light on it but i dunno if i can make it flower it faster or if i could do anything better let me know please

what kind of lights are you using what nutes what medium umm there is probably like a million other whats that everyone can ask we can't see what you have going on we need much much more info and pics cause well a pic is worth 1000 words

I'm suprised it's still alive. I won't even start on that blacklight bullshit. At this point, you might as well piss in it. If it was going to die, it would have already done it.
