I've always wondered why my plants leaves point up.
some say it is a sign of magnesium deficiency - the so called 'praying for magnesium'
Many plants can change their leaf angles and orientation in response to a change in light. Some do this to increase interception while others do it to avoid high light. A good example of optimising light interception through leaf move-ment is given by Oxalis oregana, an understorey herb of red-wood forests in western USA (Figure 12.4). This plant is able to track sunlight on dull days, but can change leaf angle from horizontal to vertical in only 6 min if exposed to full sunlight (Björkman and Powles 1981). In this way, leaves can maintain maximum photosynthetic rates under a variety of light conditions. Omalanthus novo-guinensis, an Australian rainforest plant, can also change leaf angles in response to full sunlight within about 20 min (Watling et al. 1997b).
I've seen that on seemingly happy plants and also plants that are less than happy. The Kali Mist seedling below started doing it in FFOF right before it started to show what I now think was bad nutrient burns. My flowering plants now are doing this a bit (to lesser extent than Jay's) and they look very healthy to me.

BTW Jay - I had my first Hop Slam of the season last night.
Those plants are not magnesium deficient!
Not sure if this applies to cannabis:

What did you think about the Hop Slam? I cant even compare it year to year because it's best fresh. I loved it. It's still sold out everywhere around here.
