Flush toilets it pot LOLSo the title basically says it. I have been using Fox and Farm nutrients in my pro mix for 2 weeks now. I am on a feed water feed water schedule. Since I use plain water every other water Is it still necessary to flush every now and then. I plan on flushing two weeks before harvest but is flushing it necessary for my Vegetative and flower growth? And if it is necessary how often should I do it? Any information will be greatly appreciated.
