Dark green leaves are a sign of nitrogen toxicity; and it has many drawbacks: including nutrient lockout, weak stems, reduced yield for starters. So you should reduce the feeding already and let the plant consume it's reserves. I strongly advice you to get an EC/PPM meter, it will allow you to stop guessing how much to feed. Anyway, give plain water for now until the leaves are a more healthy light green. As stopping feeding at the end of the grow; once the buds stop fattening, you stop feeding, that will give you 10 to 14 days for the calyxes to swell and thricomes to mature.

Hello @PureMedicin ! I am checking the trichomes with a microscope like this ( https://www.amazon.com/Forrader-Pocket-Microscope-Currency-Detector/dp/B00JEKXBQ2 ). When i see a lot of milky trichomes above 60% i am decreasing the nutrient strength at half and when i see the first amber trichomes i make a very very good flush and i use water for the rest of their life. This will help you to have a nice yellow plant at harvest with no fertilizer taste and smooth burning. Happy growing ! :facepunch:
