Praying intrigues me, but I think its just simple plant happiness
3 examples (I can sort pics if needed). I've got Strawberries praying outside, also had it with cuts in the prop last year and with plants in my 4 x 8. These are all in different environments at different states of growth / flowering yet all showing the same praying
4 x 8

Picture was take after watering..with just water (in soil)
I don't think its nutes (see pic above), its not roots as my cuttings in the prop had none when they prayed and we've a mini heat wave here in the UK so there's enough light / heat for the Strawberries outside.
Only conclusion I can come to is the plant is in the sweet-spot and just happy with every equation (heat, light, humidity etc..)
