Also, DON'T TRIM off her mid section to get better colas (or because of damage), she will get way taller than expected if you do that. IF your going to do 1 plant... top her once or twice, and strech out the 2-4 main's you'll get and be patient.
Just trimmed off a lot of dead shit from a soap project with spider mites, and killed a lot of the mid section of my ladies. trimmed it all off for the most part and in a 2.5 gal bucket of soil im tying her back already in the second week of flower i think from touching my 1000 watt cool tube thats almost 5 feet in the air... Although they are loving being so close, its counter productive to let them hog all the rays lol. (if its multiple plants). If its all one plant, do whatever the fuck you want. But if your sharing light with other plants, make sure they kinda get the same coverage, otherwise you'll end up with one huge bitch, and a bunch of small premies... no good.
