New Grower Stunted Growth and stiff, curled up leaves

[Atti]

Started an outdoor autoflower grow as a tryout three weeks ago. A White Widow auto, and a Sweet Seeds Red Poison and Dark Devil.
Past two weeks have had terrible weather, non-stop rain and cold temperatures.
The White Widow and Red Poison pulled through and due to the now sunny weather are quickly becoming beautiful ladies.

The Dark Devil though...after sprouting I already saw it had some mutant traits, but I thought I'd give it a go.
But after the bad weather, growth is stunted, leaves are very small, very stiff and curled.
Strangely enought hough, it's got as many nodes as the other plants, and more preflower as well, already showing the color of the purple kush genetics.

I'm growing all of them in soil, water PH'd to 6.3, and only just started giving the two others additional nutes.
So what do you think? Mutant problems? Nute deficiency? Or shock from the cold temperatures and rain?

And msot importantly: is it salvageable?

Probably got stunted from cold and to much water.Iwould leave them go but I don't think you will get much of a yield.

Hmm. Thought so. Shame,w as really looking forward to sampling this strain. Guess I could plant another but by now that's going to cut it awfully short to harvest before temperatures drop in September. I guess I'll just let nature run its course and see hwo it ends up.

Here's the other two. Something's been nibbling on the White Widow's leaves since yesterday, but couldn't spot anything. They're really going into a grow spurt now.
