Are you runnin soil or hydro? I dont know much about hydro, soil you wanna flush with 3X more water than soil in container, so 9 gallons of water for a 3 gallon pot. I try to set mine up so that i chop it when it gets bone dry from the flush, usually 7 days before, but check the trichs wait till theyre where you want them to be at when you chop it, if it goes dry before its time to cut it down water with distilled or RO water only till the trichs are right, i go nine weeks almost always(usually works out perferct for indicas indica dom), i wont grow sativas, i dont like that kind of a high and the flowering can get rediculous ive heard of 16-18 weeks of 12/12 before they were ready, fuck that, and i dont count flowering time until after they show flowers the trainwreck took a week to show so theyre gonna get 10 weeks of 12/12 total as long as the trichs are right if they need more time ill leave em in there till theyre ready, (id rather have more amber than cloudy) you shouldnt have to use clearex unless you wanna run nutes till like 3 or 4 days before the chop and i dont know if id risk makin the bud taste like shit just so i can juice em a couple of extra days. What was the reccomended flower period for yours? Were they showin sex before you put them on 12/12? Have you chcked the trichs yet? if you dont already have a microscope youre gonna need to get one, theyre only like $12 at radio shack just make sure its 30X or higher and that its got a light on it. All the flushing stuff is if youre using soil, Be cool 1
