I keep hearing that 3 weeks prior to harvest you should stop feeding your plants N. I'm using GH 3-part system and I was told that in the last 3 weeks completely cut out the Grow and only use Micro and Bloom. However, looking at the bottles, it appears that there is more N in the Micro then there is in the Grow.

I'm obviously missing something. Can anyone clarify?
