FF nute flush

I am using ff of soil with the complete line of nutrients. I only use about half the recommended doses. My question is about the feeding schedule and flushing. The schedule recommends using nutes right up until harvest but I know I should flush for at least 2 weeks. Should I just disregard their recomendations for the last 2 weeks or maybe just cut out the TB and BB and still use the cha ching, or should I just cut them all out and just use molasses? Thanks for any help

You certainly should not flush for more than two weeks. Flushing shouldn't take more than a couple hours, at the very most when done slowly. Even if you meant that you should flush two weeks prior to harvest, that's not usually a good idea either. Flushing removes the nutrients in the soil that the plants need to survive and they won't be healthy for long afterward. If you choose to flush, you should do so as the last watering before harvest and aim to have the soil dry out and be ready for another watering when you harvest.

I run the full schedule right up to the last watering or two. This time around I'm using FF Sledgehammer to flush during the last watering, but then be sure to let your soil dry good before harvesting or you'll slow the initial drying step way down.
