First thing i noticed is, its not topped at all (topping will produce multiple flowering shoots.) Maybe that's what your talking about when you said looks weird.. yes its weak looking and the tips of the leaves are burning, (possiable heat issues) but 76f wont cause this result. Are you giving any fertilizers? What kind of water are you using? What light are you using? Also i see a heater in the room.. don't run the heater pointed at the plant (i would try not to use the heater at all, and use the light as a heat source if possible) unless you just using it for the fan to get air moving. But your plant has grown well for a month and a week old.
