Purple leaves

on 1 of my plants the lesaves are goin purple !!!! and while feedin today i spotted a little spider ?? is it the spider

purple is a result of cold temperature. it isn't necessarily a bad thing, just keep an eye on your temps and invest in heating if it drops below 60 degrees. the spider isn't anything to worry about.

Its starting to get colder near me, my White widow turns a pretty cool redish purple at night, when the lights are off. When they come back on by the end of the day they are looking greener again. Shes looking good to harvest soon so I'm not too worried about it as long as its just the temps.
