I'm growing northern lights autoflower and today I noticed in my tent that some leaves are starting to turn purple. I change the water every week and refertilize. According to this schedule. https://www.aeroweed.info/nutrient-schedule/
The tent temperature has gotten as low as 62 at night but normally it stays around 75 to 80° in the tent . What would be causing my leaves to turn purple? Is it a nutrient deficiency? Is it temperature? The plant has been growing for 67 days now. The pH is kept between 5.5 and 6.5 the highest. I adjust it to 6 daily. I use general hydroponics fertilizers. Please help!
The purple is from it getting cold at night. When it gets cold the leaves tend to change. It’s very normal and fine. At least I believe that’s the cause of it

You don't think I need to add more fertilizer? I ordered I heater for the room to try and regulate the temperature at night. It should be here Saturday. I'm just concerned, because I saw this purple change happen to another one of my earlier plants and it didn't recover. Eventually the whole plant turned a dark purple. It was a soil plant, but this one is hydro.

62 at night is fine a little low but fine. I think my tent gets down to about the same like 64ish and during the day gets to 74-80. I wouldn’t even add the heater, only if your tent is getting to temps like 50’s.
