I use recharge and Orca in coco coir and Orca and WP Mycos in RDWC and Ebb & Flow. I add some dry Amino Acids  to the hydro grows and some Humic Acid and liquid Kelp too both water and coco. I have developed quite a cocktail for the roots. It seems to work. The last RDWC grow I just put in the root cocktail for a day and then add the  nutrients and supplements, they seem to like that. Sort of like grapping a burger and a beer after a weekend at a Vegan house.
