Do fan leaves usually turn reddish brown right before harvesting?

The fan leaves are turning reddish, brown. Buds filled out nicley. Trics are 80% milky. Is this a normal thing for the leaves to turn red to purple to brown as the plant nears the end? I just want to make sure they are not getting too cold at night as i can't check thermomitor at night when lights are off.

i think your good. Mine are kinda red too and my temp stays at 77-80 degrees.

Ok thanks. I'm close to the end i hope. Growing sativas. Is discoloring of the leaves like that just an outward sign that they are in the next phase , close to finishing? trich's are 80% milky.

Yep. they are just "autumning" off. In my room the temps drop below 65 degrees this time of year and this also contributes to it. It's a natural thing that most plants do.

Hey, get yourself a 30 power jewelers loupe or a 420 magnifier scope and you will know for sure... Peace

Thank you upthearsenal for your responce.
