i definatly considered the nute burn but i dobtd it since it had happened before. my flowering light runs from 10:00 pm till 10 am and at night it averages around 80 but it gets hot as shit during the day and no matter what i cant keep that room cool so im not sure what its like when its dark. i water twice the nute them up on the third watering and i end up watering almost everyday. i had some light leaking in recently but i took care of that
