Your plants turning yellow and curling is generally a sign of heat stress. What kind of lighting are you using, how far away and what kind of exhaust system are you using?
Your temps actually sound fine. It's hard to tell from your pictures, but judging from the pic of your plant in the other thread, I now believe that your plants are suffering a nutrient deficiency. Sorry for the bad info and to put a scare into you.
