Has anyone used royal queen seeds easy boost? What...

What up fusion! I’m using a dry amendment in my coco which feeds the plant it’s whole life, So I guess my question is will flushing this type of thing still benefit me. With the nutrients still being present in the coco this would prevent her using stored nutes as there is active nutrients still available to her even after flushing, Perhaps I’ll just do two rounds of a large amount of water and get rid of any buildups, Being an organic amendment I guess this fits in with the people who don’t flush organically grown plants,
