Flowering plant is getting stupid tall. Need Help!

So I'm new to growing and I have a unknown female in flowering. She is about 5 weeks into flowering and is in a Dwc 5 gallon bucket. She looks good she is just now over 5 feet tall and still growing everyday. It was two feet tall when I started flowering and was 7 weeks old. Trying to get pics up but having trouble hopefully soon though

just bend em over, and tie em to a stake. i like these a lot

basically like a piece of rebar dipped in plastic. come in lengths from 3 to 8 feet, getting a little thicker the longer you get.
since you're in dwc, you can use a couple of good bungee cords or tie downs and strap 3 or 4 of these to the outside of your bucket good and sturdy.
try to bend them without kinking them too bad, do it a little at a time if you have to, and tie them in place to the stake.
all the buds on the bent over piece will stand up and grow like little colas, sort of like scrogging the top of the plant

Listen to Mr. Shrubber. 5 weeks in? Your stretch or vertical growth should be about over by now.

Did you ever top it? Sounds like a vigorous plant. Next round do some training.. Post a pic.. We'd all like to see..
