Heat spike in late flowering help!

Hey everybody,
I'm coming to the close of my first completed (second overall) grow and i've got a question...for the duration of flowering I have had to close up my tent two hours before lights off making the temps spike up to high 80s and low 90s for two hours every night. How bad is this? I mean how bad is 90 degree temps for two hours a day for like the last 4-6 weeks of flowering?

there is some light-burn damage to some fan leaves and even some sugar leaves and definitely some heat stress but what are the effects of this kind of stuff on the buds themselves---which smell delicious, are sticky as hell, not crispy or anything?
thanks if you help

If your plants sativa it may be able to hold the heat a little better than some plants, lol may I suggest getting a huge chunk of ice and putting that in front of a fan in your grow room.

or get a cool mist humidifier and a fan and mist the leaves so they can weather the heat. Add superthrive and silica blast per directions.
The heat will stress the bloom. Maybe you could harvest after 6 weeks?
