flush your shit, not your plants.

flushing only helps fix problems in the substrate. Do you have a severe enough problem in your substrate to warrant a flush? If you are adding too many nutes or even just a ratio that results in one inhibiting others if repeated enough over time, then you may need to flush. This should easily be avoided by adjusting levels and ratios of fertilization based on early progression of symptoms on leaves. Flushing is something done due to a massive failure on our part.

There is many different opinions on when to flush or if not to flush at all. A lot of „broscience“ out there. Just try what works for yourself! I‘d suggest to not feed for the last week of flowering, but with X answers you might get X different opinions. For organic growing there is definitely no need to flush… :) Good luck with your last weeks and have fun with the harvest 🍀
