Late stage flowering, leaves turning deep purple ? Normal ? Hd pics attached

So I'll give you a run down of what I have:

Strain - Auto blueberry
Age - 10 weeks from seed
Lights - 150w hps and cfl side lighting
Medium - Aerogarden
Nutes - 3 step nutes... but none for the last two weeks of flowering

I am in the last week of flowering... I think. The last two weeks the top leaves around the buds are turning deep purple, not sure if its normal or if it's a deficiancy of some type.
Any info will help thanks. Happy Smokin

What are the overnight temps? Cool temps will do that.

over night temps dip to 73 and day time upto 83

Dont sweat it man they are finishing up! Your going to have some good SMOKE on stash esp with a nice cure.

Nope, that wouldn't do it. Probably normal, genetics.

Umm yea, some strains just turn purple. blueberry is one of them.
I had a cab 2 grows back with blueberry, AK and BC Sour. and the blueberry went deep dank purp, sexy as hell imo.
it couldnt be anything else cuz the ak and sour stayed green.
man.... it was awesome lol.

the sour pistils went all orangey / reddish too. it was a sight to see my friend lol.
i wouldnt worry about it, and if your flowering is finishing i definatly wouldnt put plant food of any kind.

Oh man that looks good!!! Problem? WTF lol. I'd smoke it...
