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!
