Looking nice and healthy ! The only thing I might suggest fixing is your heat 31 is abit high and you might see your plant suffering because of it later on . The ideal temps for veg are 25-28 in the day and 18-21 at night , during flower you might seek something like 26 during the day and a lower temp at night such as 14-16 to trick your plant into thinking the season's are changing . Other then that you're well on you're way to having some kick ass medicine !
-Happy Growing!
