Leaves curling ... left and right

so the latest - femmed WW - is in the 3rd week in the bubbler.

 

All looking nice - good growth, good colour, and good roots.

 

However, I have noticed (once again) that the leaves are starting to curl. Not up or down, but *side* ways at the tip. That is they are growing curved. Some lefty, some righty.

 

Now I am sure this has happened with every WW I have grown to some extent.

 

And looking at it. it looks genetic - not environmental.

 

Just curious if anyone else has noticed, or knows what is going on ?

If the light is too intense leaves will twist so the underside is facing up?

pics would help, though what you describe sounds like heat stress. how's your extraction working? I had a carbon filter clog up after time that raised temps and took a while to identify as the cause.
