just for the record ( yes this post is old ) coming from grand daddy purple him self states that temp brings out purple colors only if its in there genetics. Also some are auto purple too.
When to lower temps for purple strains

First plants I ever grew outside got snowed on in the last 2 weeks of flower , for 48 hours they were exposed to 30-35 degree temps and they went from bright green to deep dark purple, the two plants were banana kush and pineapple express, note that most of the trichomes were striped in the freezing temps

I've heard that I'm trying on plants just to see.

I agree with all of you that say, "Don't change temps!"
I never alter my lights on temps. Night gets to as low as the seasonal ability of my heat to kick on. That is held to a 10 deg. drop.
I run everything at 72 deg. F and cooling holds that to a 2-3 deg rise....Rh is set for 45%.
I have found over the years that balancing the nutrition ratio to like 4-6-6 and adding a K supplement (K sulfate) of 6% and increasing to 12%, then stopping at week 6-7 (2-3 weeks before harvest) does encourage more color expression in strains that can. I get some nice colors out of plants not "normally" thought to. I do run longer than most I see around here. Not much but, it matters to end quality - greatly!
Dropping temps at night, can have adverse effects too. Slowing of growth by limited up-take from cold roots and coloring from that resulting "def." Outdoors in cooler climates get this problem. Lends to airy and less density, smaller finishing buds....
I bet @doctorD, you don't get much drop at night either, or like I do.....
There you go kiddies. A straight answer to an old thread, can be good......

What's the lowest temps you would go when the lights go off? My room goes from 76f to 68F when lights go out. Haven't ran into problems this run but wondering if I should increase/decrease temps when they go off.

I prefer to finish cooler, just to finish cooler. 70 high 60 low at harvest... i start out upper 70s till half way through plus a bit then about 3 weeks out i start lowering temp bit by bit..

Once you start to get below 60. Things you don't like can happen.
To be more detailed. Once the roots and soil around them, begin to drop below the 60's. The plant starts to have problems up-taking some nutrients. The longer this happens with them in the light. The more pronounced the problems. Being able to warm the soil around the roots fast, can help. Potted plants moving in and out for night and day. Prolongs the period of outdoor plant life. Thing is, days getting colder, makes for pots less able to stave off the cold around them - it's the sun warming them that keeps the temp up....
Colder temps make for loose budding, nutrient up-take problems, and slowed growth rates.
Coloring aside, not good for plants, especially the roots to get below 60......

I wonder how large the purple genetic gene pool is now 12 years later

I'm on blackberry lol its looking nice and purple, for the record I believe it's maturity not temperature related.
Incidently it was a purple strain I was growing 12 years ago, I got the mother as a clone I don't have a clue what it was but it was top notch, what were the popular purple strains back then, a long shot but I just might recognise the name if I seen it.
Anyone?

IMHO lowering the temperature below ideal is never a good idea, if it's a purple strain it'll colour up near the end.
They colour up in the summer just fine when it's warm 24hrs.
Each to there own but retarding a plant for colour isn't my thing I like to keep it moving forward.
We live and learn lol
