Looks like it needs less N and more P & K and Ca!

What’s your nute schedule?

Are you growing in coco?

Z-man,

Looks like calcium is being locked out somehow to me.
Any yellow tops?

I agree whole plant pic would help.

What medium are you growing in?

Ph of your medium?

You're short on Ca, but it's too late to try and fix now. I would simply see your girls to the end, go back and check your feed notes and make the necessary changes for your next run. Still looks like you'll have a nice harvest. Good luck.

Thanks everyone, i flush with ro ph 6.0
Run off ph 6.5 ppm 1500
Soil ph 6.4
Hit with pk booster with calcium, 2ml karma put the girls to sleep. Woke up to the color return. They wont be back to there 100% but thats ok. Yes yes definitely check the notes. Weird happen to 2 out of 8. And didnt stunt their growth . Thanks again
