Tops 'Cupping' ???

So out shaking the rain off the girls this morning, I noticed something I haven't seen before. One plant was doing what I can only describe as 'cupping' . The tops were not quite curled, but formed like a bowl or shallow cup like formation. Pics aren't that great, but first two or 3 pics kind of show it. Doesn't look bad, just interesting.

The other two pics are just shots I took this morning...

Any thoughts?? @ganga gurl420 - ever seen this?

Looks like they're just praying to the sun gods?

They are praying man. Sign of very healthy plants.

Maybe cut back on nitrogen but normal for many strains
Good job

once they get into very hard flower you will see even at night they look the same. They dont go to sleep anymore.

I've noticed this exact phenomenon. I wonder why it happens, may they aren't releasing their sugars and carbs every night like they do in veg?

My God Bud's always praying, day and night
