good find RG, I haven't seen this before! I can't remember where, but I read that this angling of leaves is usually about making minor adjustments to light intensity.... Think of the leaf as the solar panel it is, and how directly, squarely it faces the light to get the maximum exposure possible; the best posture for this is with the rays hitting straight on, no angle at all,... conversely if it's a bit too much, in the leaves' case, altering the face angle so as to make the light hit more obliquely will reduce the sheer intensity striking it; the sharper the angle, the less directly (squarely) the light hits,.. this affects the heat absorption as well of course, and all the implications for VPD, etc., associated with that.... We experience this ourselves every day, dawn and dusk right, so called "weak" sunlight.... color spectrum changes then too but that's another topic altogether!All caught up! Sorry again to read about the Hermie... That always stings. This is me when that happens...

Now @Waira can correct me if I'm wrong but regarding the "praying leaves" "pointing up leaves"... I always contributed that to transpiration rate being optimal or at 100% transpiration rate. Over watered or bone dry they are completely droopy (zero transpirtation). So do they do the opposite when they are in the prime zone?
Food for thought
Looking fantastic by the way!!
....So is the common pre-sunset/lights out drop in petiole posture that looks like over/underwatering symptoms (it's not, leaves stay same shape, it's the petioles only that "relax"), which was sorta explained by AutolowRyder, which I now frikkin' forget where...... I wanted to ask him more anyway, so I'll PM him to see if he can expand on this,.. but it's some sort of physiological "gear-shifting" response very basically put....

Oh my yes, bad VPD is hitting the "machine" right where it hurts most, so much depends on the ability to transpire well, anything that screws that up can bottleneck many things downstream of that... it's a combo-stress event, not just one thing like a simple defc., physical trauma, nute burn, root trauma, etc.,... This is a known cause for triggering hermie manifestations...Thank you I looked up the PAK and she looks very nice, my list of strains is unattainable in my lifetime.. Sigh...
My VPD was in the red, and I never really put it together that it could have that big of an impact on the grow? Looks like it can tho.
I gotta check up on your thread, I'm still doing catch up.
:smoking: OGC looks nice RG, a photo' right? .... yes, the impossible gotta-try list! I suggested her because I think she'd be a good fit for your conditions....
