hey guys, kind of a noob here but just have a general question. My plant is 4 weeks into flowering and doing well, feeding 1/4 strength FF trio every other watering. However I heard Fox Farms recommends flushing every 4 weeks, should I do that or should I just flush 2 weeks before harvest like they say to?
Also, what is the best method of flushing I should do? I’m not really sure how to go about it.
