Rather than water on a specific timetable, dig down a little near the plants to see if the soil is damp or dry and water when the soil at root depth seems dry. Whether watering every day makes the soil too wet depends on how much water is given at a time. It can happen that not enough is given to allow moisture to get down to the roots and it evaporates instead.
Having said all that, it's not unusual for the lower leaves on a plant to turn yellow from simple ageing. It may also mean the plant needs fertilizing but I wouldn't be in too much of a hurry to do that if they were only recently planted.
