Seedling leaves pointing directly upwards? Actually vertical

Hey guys,

here is one of my jack herer seedlings that is in a dwc bubbleponics system. Air temps are mid 70's to high 80's, humidity is 50-70%, water temp is a constant 68F, ph ranges from 5.6-6.4. They are vegging under a 125w blue cfl that is hung vertically about 6 inches away.

I'm using tap water which I know to be fine, along with the appropriate amount of superthrive. All conditions as far as i know are within the optimum limits.

The only thing that I could possibly see causing this is about a week ago I forgot to turn my fan on and temps soared to 90f n res temps were in the mid 80s. Since then the seedling stopped growing for about 4 days, until about three days ago when it's leaves did this:




Sorry the first one is a bit blurry, but you can see what's going on - I have never seen anything like this before - it's totally bizarre!

Thanks a lot for any help =)

looks all right to me, but do watch those temperatures

I think you need to bring your light closer! Its reaching to get the light!

I second MaiaPax

3rd it! lol

cool ok guys, thanks a lot - gonna get them under either a 400w or 600w mh soon anyway so =)

Your pH is too high. Leaves downward = pH too low, Leaves up = pH too high. Move your light closer, It could be reaching for the light too.. 1.5 inches from it.

I have the same problem. Out of 8 plants, only 1 of them was growing pretty much vertically. It still is, even after its 5th set of leaves. But on the bright side, it's the densest plant I've got.
