Hi Bower,
I have similar conditions here in Alberta as you speak of. My GH swings from 40 at night to over 100 some days and all temps in between. Many of my plants were some stage of purple at all stages. I transplanted many to bigger pots. They are looking good. I don't see any more loss with plants with purple leaves. I say. " If they can't take the Canadian climate, let them die" and nurture the tough ones for better seed stock. My issue is more with the cultivator. Most of my losses was with a pack of Mortgage Lifter seeds. Not the variety, I think, just poor seeds.
