Those plants are super stretched. Cfls should be kept between a half inch and 6 inches from the canopy.
As for watering it looks like your doing ok, maybe overwatering a bit, but you shouldnt be following a schedule. How often you will have to water depends on the size of the plant, its growth rate, and the size of the pot. What i do is i wait till the top couple inches of soil i can feel into without disturbing the roots feels dry and thats when i water
Also starting in large pots is not a good idea imo. I like to start in solo cups, then move to 1 gallon, 3 gallons, then i flower in 5 gallons. The pot being too big causes it to dry slower and overwater easier
