You are feeding too much, getting nitrogen claw due to excess. Back off the nutes, and see how it responds.

2100ec!!

Try 300-500 ppm on the .5 scale. Lol but rinse the bejesus out of them first. What's your starting water ppm? And what are you adding for nutes?

 

[Jimster]

They look to be suffering from Nitrogen toxicity. I grow in Promix and use a lot less nutrients but still have great results. Force feeding a large pizza daily isn't any better for plants than it is for people. I'd cut the nutes back for a few days and pour a few gallons of decent water thru them to flush the excess out of the soil/coco. Less is often better!

Agree looks like overfeeding I bet the PH of the soil is very low as i'm seeing signs of a lockout. Flushing as was suggested would be where i would start followed by a light feed.

looks like your clawing is only up top, atleast what I can see, maybe your light is to close or you are getting to high temps sometime in your schedule.
