Temp. question

i have some plants that are like 6 weeks into flowering. last night it got real cold in the bedroom, when i went in this morning alot of the hairs had changed color. Is this because of temp. or because they are about done? let me know thanx

Could be both hard to tell without pic what strain was it?How big of a temp diff did it hit?

i have a blue widdow, 8 ball kush and cali. orange. it got down to like 60 F. the blue widdow and a 8 ball that have changed the hairs prier to this and the cali. orange did it over night so i am just kidda in the middle here.

60f aint nothing, if you were in the upper 30's lower 40's for most of the night it might be something to worry about and it is not pistil color that tells you when to harvest, its trichome development and bud swelling.

im aware of this. but i was just wondering because they where all white and tall yesterday and after the cold night they shrunk down and changed color
