Can anyone tell me why some leaves are nice and green and others are dark green/black? I am 2 weeks from harvest and a lot of leaves have turned yellow/brown which I understand as part of the process, but dark green or black?

Nitrogen abundance...too much nitrogen available to the plant :)

Ok, excuse my ignorance but I do not know what nitorgen is. I use GH so is it too much Micro or too much Bloom? A local buddy thought it was too much CO2. I had it at 2500 ppm so I have since turned it down to 1600 ppm.

One more thing, they were left without water for 9 hours during the day cycle 4 weeks ago,...could that have contributed to it? All the leaves were drooping when I walked in, I just about freaked! lol.

If your going to grow marijuana... you really ought to read up about what Nitrogen is, also read up on Potassium and Phosphorous.

Youve got N(nitrogen) abundance. Most of the N is in the Micro, and there is little or no N in the bloom. You should cut back your use of Micro at this stage, though I don't know the exact recommended ratio.

theres alot of controversy as to whether flushing is needed or not. I don't have the experience to say one way or the other but I would suggest you consider doing a flush. Read up on it and decide for yourself.
