100 degrees F is pretty fucking hot if you ask me. They should never be exposed to temps like that. Even temps sitting at 85 aren't acceptable to me unless you have Co2 running in the grow room.
Looks like the top leaves are getting most of the abuse, so it's either too hot in there or the lights are really hot and you need to move them up. Can you get better pics?
"proper temperature for most marijuana strains is between 70-80 degrees, but using carbon dioxide will allow you to grow in temperatures as high as 85 degrees. At night, the temperature can drop 10-15 degrees without harming the plant."
