PLEASE HELP!! Purple strain

OK so I have a couple Fem. Ice bomb (vanilla kush x white rhino x bomb #1 from bomb seeds) which grown in the right conditions will turn purple. I get a few mixed answers when researching, but I get it has to deal when it is in the flower stage(no where near, few days old, but yet it is a 65 day seed to harvest) so my questions are the temps? When should I start and end? Any other suggestions?

Please help!!!
Greatly appreciated

Start and end what ?

What is end? And strains dont usually just turn purple. You could youtoube some stuff but they wont stay purple. The purple is strain dependent.

I didnt really realize I put end but meaning starting like when do I start lowering temps at night in the flowering stage? ive also read something with nutrients? Dont know how true...ive seen some videos but different people say different things im trying to figure out what would be the best for me....and there is purple tendencies I guess with it im assuming the bomb #1? Atleast how the description read

If the genetics your talking about have a tendency to turn purple then you have a pretty good chance at it turning purple, regardless of temperature or nutrients. But if your plant does not genetically have those tendencies you can try to bring out the purple coloration by keeping the temperatures below 50-60f during flowering, and when lights are off preferably.
