Every now and then I'll have a leaf spin around upside down on me. Last night I did a res change and this morning each plant has an upside down leaf. Btw, my lights are on evenings, off daytime so the lights have been on all night since the res change.

Is it reacting to a pH difference or....? I did increase the nutrients but only from 800ppm to 880.

I may have lowered the light a bit too since they are stretching some but it's plenty cool in there, not over 80.

I know this is probably nothing critical but if anyone has seen this and knows what the heck causes it I'd be grateful.

Oh, another thing while I'm at it - sometimes I notice a few of the leaves curl up along the side edges. I dont mean the tip curls up, I mean the sides start to curl up. What causes that?
