im doing 10 plants in the atami wilma system useing only 100% canna coco with the pump going on for 15 min every 3houre useing green dream bloom nutrient

i then have 10 outher girls in the same room planted in a mix of 1kg bat guano and 2 bags of canna coco in 10 litre pots with these girls the ones useing bat guano and canna coco will they need nutrient feed or should i just water them daily also do you recomend me upgradeing my light what do you think would be best for a 20 planter soundo
