Cold Temperatures

Just wondering what affect can cold temperatures have on Marijuana plants?

it locks K and P, also makes CO2 harder to absorb as the humidity tends to rise in cold environments, mold, fungus, moisture stress.. hummm how cold are we talking about?

turn them purple. slow growth, kill them if its too cold, make them stretch, a whole buch of things it depends on when and how long it is cold for. and how cold it gets

makes the buds purple...

but slows down growth

Can it cause thinning of new growth? In the day 70-75 but in the night during veg for six hours it may drop for a couple hours to 40/50. This problem will be resolved in a couple of days i'm not quite sure if this is the reason for thinning of the leaves *rubs chin*
