Leaves changing colors

Hello everyone. My plants are going on to my 7th week of flowering and because of the cold my strain tends to get purple hues. But now I notice that they are starting to get a little bit of yellow/orange spots on some of the leaves. I’m using soil and the last two waterings were plain Ph water between 6-6.5 . Any ideas?

Chlorosis is normal in late flower, but it may help with diagnosis if you retake a picture in white light.


@Aquaponic_Dumme I would but they just went to sleep. Probably should have done that lol

You beat me to it

Any ideas? @Aquaponic_Dumme @Majiktoker

Looks like potassium or phosphorus deficiency

What strain is she? How often are you feeding & watering her?

@Aquaponic_Dumme @Majiktoker it is OG kush and sour diesel hybrid but the more fruity version. When it gets cold it turns purple . I water every 3 days now and I water plain ph water twice for every feeding
