yellow plz help pics

why is my stalk yellow? also how do i keep her warm at night so she dont freeze?kiss-asskiss-asskiss-ass

Get a space heater, or depending on how much heat your lights give off. You can switch up the light schedule so its on at night to keep it warmer and off durring the day (you will have to have it "light tight" so none is escaping into your grow area).

As for your yellow stalk, i have no clue. It could just be your strain.

whoa, those stems are way bigger than they should be for the size of those leafs?

shes outdoor forgot to mention.
