That's enough ! 6 days are ok depending on how your plants are being watered.
This thing works very fine, and should last easily the 1 week.
Care not to over water AND apply this watering system, so you don't drown the plant.
btw, just saw your diaries, yous plants are too wet, if you don't let it dry the roots won't be develop until the flower time.
No roots or small roots on flowering you give all kind of problems possible, and nothing will solve because there's no root development on flowering. Also, if you kill roots on flowering (like you might be doing right now) it won't develop again as it develops on vegetation stage.
Just water the plant when the pot is light, the plant is dropping, and the soil is really dried up.
Also, make holes around the pot so the root may seek for oxygenation, roots need oxygen. otherwise they don't develop or die...
