First time DWC w/ white widow...looks fine but leaves curling up....w/ pics

White widow plants are about 2 weeks old from seed. I dont think its life threatening but one of them has leaves that are curling up for some reason. Roots are bright white and are just starting to come out of the bottom. Just wanted to see if anyone else has seen leaves curl up like this one...

Ph is @ 6.0, checked daily.
I use and ice probe so the water temp stays b/ 62 and 65 degrees.
Solution is distilled water with a tiny dash of Superthrive, Root 66 and Sugar Daddy.
Temp-70-75 max
Humidity-48%

Slightly too much nutes on these little ladies. I have the same prob in my clone room if I give them over 100 on my ppm.

High ph can also cause twisted leaves. Be sure your meter is calibrated of course..

^Exactly what I was thinking. Are you sure your meter is calibrated? Those twisty leaves are the classic sign of high PH, that's why I'm asking.



EDIT: Damn, I didn't even read your whole post, i only read the part about high PH, then I responded almost exactly the same.lol Must be right then, eh?

hehe thats funny

yeah that looks like a PH issue to me as well.

Cool, pH seems to be the general consensus. My ph meter geeked out on me last week...I have a new one on the way but in the meantime I've been using the pH test drops. Obviously an inferior way to check it but until I get my meter it will have to do. I changed out the solution and am now just using distilled water and a drop of superthrive. Thanks for your alls' help and I'll update in a few days to let you know what the culprit is...

Best of luck!
