Clawing

[NZwarrior]

Hi guys just having an issue on a couple of my plants when the tips of the leaves are clawing down

I'm growing in coco on a 6 on 2 off light cycle I'm feeding everyday with cx nutes pH is at 5.8 when I feed.... I've looked around but can't seem to find anything about clawing down is it a huge problem?? Not all of my plants are doing it

Thanks for any help

Looks like perhaps a tad too much Nitrogen.

That's what I was thinking I only see a few yellow tips so you may have caught it in time to reduce the damage...don't know much about hydro/DWC...but that plant looks like she's on steroids and wants a break from feeding
EDIT: must have confused this thread with another what type of soil are you using? Yeah she's been over fed! If you're using a soil mix with nutes in it, cut back on watering, cuz damn, dem leaves is curled and shiny

I'm using canna coco pro plus... I did think nitrogen overdose so I started feeding a little less MLS per litre I'm hoping that's it
