Purple tips I am confused

[Gboi420]

I can't find anything online about this. I am getting purple tips now. I know I have nitrogen toxicity I am doing a flush in a couple days with the correct pH. It wasn't 69° in the tent like it says. But I have been having problems keeping it above 70° in there since it got cold outside. Could that be why I'm getting purple tips? Scared to run the fan. What's weird is I have 3 younger plants in the same tent and they don't have purple tips. same soil and water feeding.
