First grow, in hydro, DWC. Using CFL lights for this grow, I have about 16-18 26Watt CFL's, a mixture of 2700k and 6500k. I started flowering on 4-11-12... So that makes today day 45 of flowering... I'm growing sensi seeds Big Bud, which according to their site has a flowering time of 50-65 days... I do not have any flushing solution, so I was just going to give her plain distilled water to flush before harvest. My question is, when? I've read to flush 4 days before, 7 days before, 10 days, and 14 days! I know I want to wait for about a 75% cloudy 25% amber to harvest, but if I want to harvest it THEN, how do I know when to start flushing BEFORE it gets to that point. Here are a bunch of pics, I have my wife going out later to get me a microscope from radio shack so I can look up close at the trichs, but I'm imagining they are all still clear... I don't know though since this is my first plant... Any help would be awesome right now, and yes, I know, this thread is all over RIU, but the information varies from thread to thread and it makes me feel better to post pics and get first hand opinions on MY plant and what to do... I'm using greenleaf nutrients, they imitate major brands, so I got their general hydroponics flora series imitation... gro,micro,bloom... I'm running at about 1000PPM right now... 2.5ml Gro - 7ml Micro - 16ml Bloom per gallon of water. Here are pics.
