@Dutch_Headshop, sorry for the late response. I stopped giving them nutrients in the water about 3 weeks before harvesting, as well as giving them ice water from the fridge (~5 degrees). Also at night I keep the door to the tent open so the night temperatures drop to around 16-18.
If I had to guess what made the biggest difference I would say the straight water, as well as the night temperatures. I am not so convinced that the ice water did anything really.
Groetjes uit Enschede trouwens!
