If your plants are yellowing on their own, like almost all the sun leaves are gone. You have already let the plant flush itself. If on the contrary its still really dark green it'll taste more like chlorophyll than anything.
I have lots of experience with this. If you're growing in soil and and have not over-fertilized your plant(s), there's no real need to flush. There's no effect on the taste, etc. Simon
What about in hydroponics? And I have over fertilized at one point but nothing significant, just slight nutrient burns at the tip.
It's running in an aeroponic system with ph in the range of 5.5-5.8. There are two 1000 watt sodium lamps. Feeding it with advanced nutrients bud factor x, rhino skin and sensi bloom base. Temp is held around 76 and humidity at 50%.
