Indica Harvest Question

[ToxicWaltz68]

My indica's leaves are starting to get purple (i read its from the cool temp outoodrs) and the pistils are about 40-50% brown. Is this plant at its peak or should i wait one more week to harvest it ?

Most people tend to go by the color of the trichomes for an idea of when to harvest... not the "hairs". I have had pistils turn on me just 3 or four weeks into flower and it obviously wasn't time for harvest.
