Overwatering.

it could be over or underwater... the way they curl im thinking under...
the yellow leaf is telling my there in need of way more nitrogen..and the twisting and light color is telling me there mag short aswell...maybe its a ph flux/issue...

Hey digital they where wattered and ph was proper as it turns out I must be missing somthing in my my tea probally like you said Magnesuim or some other trace elements as i gave them a dose of Chem ferts at 550 ppm two days ago and they totally recovered, all leaves have streightend out.The had a nice growth spurt of two inches in the last couple days. Dam I must be missing somthing in my tea mix. I have all three npks as im using kelp, bat guano, alfalfa and wormcastings. Back to the drawing bourd we go

I think you're over watering which is causing N lockout, just a guess because the in the pic the soil looks wet. I also have dealt with overwatering and my plants looked quite similar to yours. how dry is the soil before you water?

 

[skunke]

Ya i let the first layer of soil dry out, it must of been a deficiency, as i waters with 500 ppm of chem ferts and they perked right up agian.
