Strange Leaf Curling

I'm new to Bubbleponics using a GHWF and noticed that some of my newer leaves are curling strangely sideways.....any ideas what this is from?

Any help would be appreciated.......peace.

Curling up-Heat stress
Curling down(claw)-Overwatering, over fert
Twisted leaves-Ph problem

A pic or two would be helpful.

Great, simple tool to use.....

with this twisting ph or watering....if ph, too high or too low?

Thanks again....

A PH meter is really a necessity if you want to grow cannabis!

I'm using a ph meter, digital.....

so is this a ph problem or watering problem?

Ph problem

For hydro, pH should be between 5.5 and 6.5. ....5.7-5.8 is idea.

Looks like its re-vegging.. is it a cuttling taken from early flower plant?

no.....but I did find some spidermites when it had just rooted and was able to clear them out.....she stopped sprouting for a couple of days.....maybe re-vegging like you mentioned?
