okay the whole point of coco is so you can water multiple times a day. you do not start out this way! you must get a good root ball first. then once that happens your plants will be begging you for multiple feedings a day. yes you can ad some perlite and water once a day or two but your not going to get the whole point of going to coco. to get the growth of hydro and you will not get that growth unless your feeding multiple times a day.
