Seeking light. probably perpendicular to the light source, eh?
The excess 'praying' of the back-right plant in picture #3, might be a sign you need more light. Leaves angling upward is a good sign, but when it is extreme, that's potentially a symptom of not enough light. This stuff is a matter of trial and error because each garden has it's own local variables that impact exactly how much light a plant can handle per day. It's better than drooping, that's for sure, lol. Maybe get the light an inch or 2 closer and see how it goes for a week.
The resulting spacing of nodes (new growth) will help guide light intensity --- too tight? needs less. too strechy? needs more
if your temps, rh and atmospheric co2 remain consistent, it'll be roughly the same next grow too... some seasonal differences are possible. A little cooler or less optimal VPD and you get less potential photosynthsis per day possible (less DLI needed than other seasons, for example).. take notes.. if temp/rh vary, expect some slight differences from one grow to the next, but it'll mostly be the same.
