Cfl scrog temps need advie

Basic info:
FIRST GROW
DWC scrog with 3 300 watt replacement cfls (68 true watts)
2 weeks flowering
Tiger bloom, calmag, bat guano
Strain is blackberry
Day time temps : 77-82, 25 to 45% humidity and night time temps remain the same
Its in my bedroom closet, poor venalation

My question/concern is my night time temps, I have no way of dropping it the desired 10 degrees,
Everything seems okay, seems to me like its flowering rather slowly tho, does anyone know what kinda damage high night temps can do?

Any advice is much appreciated.

Anyoneeeeeeeee

proper ventilation is the answer mate the only way to drop temps is by getting the hot air out the grow area

I kno, I can't have a ventalation tho, will it still be okay with the high night temps or will it cause problems?

Buellerrr....
