Good advice.it doesn't hurt to flush periodically in coir, the worse that will happen is that your nug will smoke better. i prefer 800-1000ppm in a hydro style feeding program. it's all dependent on your strain and light intensity, how hungry is she? she'll let you know.

For all flushes, except my pre-harvest flush, I use epson salts or a diluted amount (1/4 strength) of the fertilizer I am using in that given stage. Epson salts have an amazing ability to leach out natural salts that build up in soil or hydroponic mediums. Epson salts also have the ability to leave behind traces of magnesium which is commonly locked out with salt build ups.
To use epson salts as a flushing agent, mix 1-2 tablespoons per gallon of water and run the solution through your soil or hydroponic system. My second option, 1/4 strength fertilizer, works to pull out excess nutrients because alike molecules tend to bond to each other. A diluted fertilizer will leach out more salts than plain water alone.
For recirculating hydroponic systems, run an epson salt formula or diluted fertilizer regiment for a few hours and then return to your normal fertilizer mixture. If your plants are stressed due to a salt build up or a nutrient deficiency it may be a good idea to refill the nutrient reservoir at 1/2 or 3/4 of normal strength until your plants show signs of recovery.
