im only into dert so i cant say nuffin on coco grows...however back in the 70s an early 80s i grew outside and back then all there was to use was miracle grow kinda nutes..used to mix it up in gallon jugs..and carry it to plants..had good plants...wasnt all the hybrid mixed strains as now days tho...i think the reason some folks shy away from miracle grow is sum has times release nutes and they think it prolly is to much, but i never had issues when i used it outside back then and also now days the Soil ya get now days has a lotta extra trace elements ect in it as well as all the grow nutes now days has a lota stuff in it so it might be better but miracle grow shud do fine if you go easy on it and if thats what people can afford more power to em..GL
