PLS HELP whats wrong with my leaves?

iv noticed leaves curling is this a problem? this pic was taken about a week ago 4weeks in flower,
i checked 2day and they look like there getting worse
 
Too hot and the plant is trying to retain moisture, also known as the Taco leaf.
its been gettin really cold so iv had a little electric heater in my 1.2 square metre tent at the bottom, it was set 2 turn on 5min every hour but was still cold. i like to keep temp about 27*c but its been dropping as low as 7*c now iv set heater to 15min every hour and raised it half way up my tent above the plants. now you have said its gettin to hot maybe my heater is drying out the air?

during light on the temp should be at 24*C and when the light is off , the temperature shoud be under 20 , at a minimum of 16*C

27 is to much

buy a thermostat and install it to control your heater.
if u keep the heater on for 15 min. you will get heat stres and burned leafes becouse in those 15 minutes the temperature will go way to hot in that small space.

the heater and the thermostat costed me around 25 $ and i keep a steady temperature of 23*C during light and not lower than 19 during the dark

44.6 is pretty low, but its not causing this problem. when i started it was in a basement in the fall/winter time and during lights off it would hit 45-55f everyday in winter and i never really had any issues other than when they were little it took them longer to take off growing, but once they did i was alright. Point being-It would be better to keep the temps up about 60f+ lights off, but its not whats causing the leaf curling most likely, i never had it happen to any of mine.
