Is she dying or is it normal?

Hi All
Can I ask for someones advice please......
The strain I have is Durban Poison. She's about 3 weeks into flowering but over the last couple of days she doesn't seem to have grown any!!.

I have checked the 'problems' forum but couldn't relate to any of the symptoms.....however I am a novice and probably can't see the woods for the trees (the probs mentioned there, I just haven't seen it).

If you have a look at the pics you will see that some of the leaves are turning purple...is this normal for the strain or have I got some kind of defficiancy

If so what would be the quickest remedy as I havent got much time left with our weather (UK).

Thanks in advance

I think the purple may be just from the cold.. but I don't know about the stunt growth.. may be from the cold too I guess..

iv read on a few other people's outdoor grow that they went purple when it started getting cold.

it has started getting cold recently here in the uk so i would say its just that.

not sure on the stunted growth though sorry.

purple = cold

Growth stunt, couldnt say :S

dude that shit looks DANK if u want want it ill have your purple wonder!!!

Thanks people. At least now I know whats causing the coulor change. I'v just fed again with tomato feed to see if that helps!

the strain has natural purple also

those plants are doing great, let them go as long as you can durbon poison is really good in the cold and youll be rewarded with some fat purple nugz... peace
