I'm hoping that you started your flush to get rid of the stored nutrients in the soil, forcing the plant to use up it's own nutes stored in the plant itself. This wil rid your plant of unwanted taste and aroma caused by nutes hanging around in your buds. Definitely so a 3x flush (flushing with 3 times as much water than you have soil. Example 3 gallons of soil needs 9 gallons of water to go through it) that helps a lot more than just a normal watering with just water. Just flush loke that once in the beginning, and once 3 days before the day you picked to harvest. Remember that the plant takes nutrients stored in the plant and pushes it down to the soil at night, so chop your plants BEFORE your light turns on at harvest day! That will make sure that ANY nutes left in the plant will stay in the soil when you chop. And if you're not completely positive when they're ready, put your camera lens up to the magnifier you got to check the trichs, that will work great to post a very clear picture of where your trichomes are at. And ALSO remember that harvest time also resides on your preference of high. If you like a nice energetic head high, then you want to harvest earlier when you have around 15-20% amber trichomes. Looking for a real intense body high? Then wait a little longer for more amber trichomes, around 60% amber is the LONGEST you want to go though because this is where your potency will start to degrade and your high will be too harsh and tired... Me personally, i like to harvest at three different points! In the 20% amber stage, the 35% amber, and the 50% amber! Hey, variety is the spice of life haha. And it's nice to have an energetic high for during the day, and a coughlock narcotic high to undwind at night. You can do this on a single plant too, you just chop individual branches and allow certain ones to further ripen. The plant is already going to kick the bucket towards the end of flowering, so don't worry about messing up the buds still left after chopping most off. The point is that just being connected to the plant's moisture is enough to futher ripen the buds. So if you take this all into account, you'll get everything you hoped for with your hardwork, effort, research, and most importantly your PATIENCE! haha, enjoy the fruits of your labor brotha! Any other questions just message me up man. Take it easy brotha
