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 ! 👊

Hi everyone, I need some advice here. I am currently using a 200W dual spectrum CFL for Vegatation however I know that I will require a more powerful setup for flowering, if I want to get a good yield from all 3 plants. Can anyone tell me what would be better, HPS or LED?

Do you have any watering tips? No way to find out what is the best way. Do I initially water with less water but more often or soak the whole pot? Someone who has experience with airpots?

First hydro. Is there anything I'm forgetting about ppm, maintaining pH from the resevoir, keeping rot from growing (non-issue with hydroguard right?) , etc? I plan on something for light, and change the jar and nutes if needed. Will let the roots breathe at the top.Canna->Lucas.

Good evening, When looking at the trichs under a microscope, I am noticing basically just clear or clear with red tips, and no cloudy trichs like my last grow. I don't want to go much longer, the buds look great. Any ideas? Can I harvest part now and some later with autos?

Remove lower branches Would it be beneficial to also remove these lower branches? It's my first grow so I'm not sure if this would be useful. I'm in about week 3-4 of flower, but don't know if this would create bigger buds on the main branches. Experienced growers help me out pls xp
