In this week the plants looks so healthy, they only needed water and a little more dose of nutrients. In the second picture you can see the coco so dry because i thought It was overwatering the plants, but i investigate a little and i realized that is very difficult overwatering your plants in coconout and more so on aeropot pots Since It make i dry faster. I trasplanted the plants to 7L pots (It is not yet final) and i'm sandwiching mammoth and roots Excelurator in every watering. Im watering once or two at day with 200ml with nutrients and 50-100ml of only water in the second watering.
