Dude... let the plant grow to FULL maturity! When it starts to get cloudy triches and the calyxes start to swell, feed 1tsp of ORGANIC, BLACKSTRIP MOLASSES per gallon, every feeding (every time the pot gets DRY! I actually do this throughout the entire grow, use molasses.). Then AT LIGHTS OUT (ADD a 4 hr lights out if you're at 24/7 light) start cooling the soil with ice water/ice cubes. Just fill a bowl up with ice water and dump that shit on the soil, let the cubes sit on top of the soil! This will induce the plant (aka SHOCK THE SHIT out of it) to want to reproduce, in it thinking that it's VERY SOON going to die! You're doing nothing but mocking the first frost and or winter by doing this. The plant will push EVERYTHING it's got stored in its roots to the buds, in hopes of reproduction before death occurs!!!
You will notice NOTICEABLE gains in size, denseness and trich production! Also, if side branches finish FIRST, or vice versa - chop at different times! This will give the plant time to focus its "new found energy" on parts of the plant that hasn't fully matured. Works EVERY TIME for me, AND THAT'S WITH SIDE BY SIDE COMPARISON!!!
*Also, the icing down and the water that the ice produces will help with FLUSHING the plant of built up salts and other unwanted "things" in your soil - for a GREAT, SMOOTH, COLORFUL smoke!!! Yes, ICE MAKES BUDS CHANGE COLORS! Once my plants leaves have ALL almost "died", that's when it's time to chop chop chop!!!!*
