Is there anything wrong with this plant?

I have two white widows and two Northernberries under 400W HPS They are both entering their third week of flowering. I am noticing the leaves (the entire leaf- not just the tips) are all pointing upwards on one of my white widows. Their coloring as well as everything else is perfect. So I'm not sure if there is something wrong or if this is normal.

i grow widow mate , its normal , i like to see my plants doing that . no need to be panic. heres a few widow clones i have going at the min , there are a few nycd and pot of gold in it too.
