Dark leaves - possible N toxicity?
Much better....but I still think you're going to have a bit of a fight later on....they look pretty damn happy and growing well there.
Weedhound Reviewed by Weedhound on . Dark leaves - possible N toxicity? Ok, I've got kind of an oddball situation. I've got 6 clones in a DWC system sharing a common reservoir - you can see a pic here : http://boards.cannabis.com/hydroponics/151678-sog-gone-overboard.html. They've been growing fast and I've been gradually increasing the nutrient concentration, intending to push it as high as I can until I just start to see some nute burn, and then backing off. This morning I woke up to find that one of the six appears to be showing signs of nitrogen toxicity - Rating: 5
