theres not a set schedule. Water when the soil feels dry up to your knuckle. Also pick the pot up and feel the weight. You will get an idea by how heavy the container is if it’s time to water. As a new grower er on the side of caution and try not to over water.
Plants are only seedlings for about a week. By week 4 even from seed the plant is mature enough to flower. Every week that plant is going to double in size and so will it’s drinking habits. Just pay attention and you’ll be fine
