100 degrees+? Jesus dude. And also did they have any pre flowers before you switched? If not then it could take another week to two weeks to start showing signs. I only think sativas grow in that temperature well and those have up to 12-16 weeks flowering periods my friend.
Jiffy pots aren't good at all, it's come in the bio degradable netting, and the marijuana roots grow so rapid that they get twined in it. You can use them, but your going to have to rip that netting off before the tap root grows thru the bottom.
I try not to be a fat-ass, but when I have the munchy urge, I can't help myself.. I hate doing it cause I regret it the next day shitting my brains out. Swiss cake rolls are the shit.
