Just my two cents, but that's a lot of frequent watering... the more often i water my girls the more the leaves tend to look droopy like they're filled with water. I'd try less frequent waterings, like once every few days, and use a decent amount of water. Cannabis just like tomatoe plants really like their soil to get dry before they have more water. the top leaves should be sticking up in the air like they're "praying" or look like the people in church holding their hands up. Goodluck with the issue!
