In fact, I did an 80 run of CDD last grow and I liked that version better than any other I've grown. The taste and the high were both at their pinnacle IMO.
CDD is good any time after 60 days, but gets better at LEAST up until 80 days. So there's plenty of time to get a good flush in.
As far as the flush goes... clean is clean is clean. If you don't feed very much in the first place, your flush might not take very long. However, if you feed em hard, then you'll need to flush longer to get them to yellow up.
I recently read an interesting theory about flushing... I just started to experiment with it last night... Flushing with out-of-range pH water. In other words, giving the plants ONLY water that is not in the pH sweet spot of between 5.7-6.3 (ish). I gave a nearly finished plant water at almost 8.0 last night. The idea is to lock out nutrients by giving the plants water at a pH that won't allow nutrient uptake to occur. It's just a theory right now, but it sure does make sense. The only thing I can see getting harmed is the taste... but that's not proven either. One way or the other...I have an experiment under way right now to see for myself if this theory can work. If it DOES, I may be making some changes. Stay gooned.

It makes sense. I wonder, though, if other elements that are usually NOT allowed entry will suddenly be in range with these high or low pH ranges. Know what I mean? What if... let's say, mercury were not allowed entry at a normal pH range, but it IS allowed in at a higher pH. Mercury is just an out-of-the-air example for the sake of argument, nothing factual. All I wonder about this idea is... what --if anything-- WILL be allowed to enter the roots at these high or low pH ranges? Gotta get an answer to that question.
