Have you been checking the pH of the nutrient solution and the runoff?

shouldnt the soil be able to get it down to the right level? i have checked the tap water once, it was about 7,8...
i do no longer have a PH meter, but thanks anyway

i thought it might be deficiency as well, as i have only fed them once with nutrients, so yesterday i gave them some and i already think they look better.

does nutrients raise or lower the PH value of water?

Nuts and other additives can deff mess with your ph. go get ur self a digital waterproof ph meter.

Im very thankful for all your help!

i think i have solved the mystery.

i have 3 small plants as well wich i only fed with clean water so far and they showed the same symptoms, so i guess the PH of the tap water was to high, so by adding nutrients i might have lowered it to a more proper level.

I had a PH/EC/TD combo meter wich i sold to a m8 who was growing hydro, but i guess i should regret that now :\.

Thanks again peps

Nothing is deficient, your ph is out of wack. The contorted leaf tips are a dead give away. Becuase your ph is out of range some of the elements are unavailable to the plant, this does not mean anything is deficient. Correct your ph problem and back off on the ferts, you have some burn going on. Good luck with your grow.
