3 week old Critical Rapido CLAWING! Pls view pics and help!

[bongwater923]

One out of three of my Critical Rapido autos started severely clawing overnight and is getting worse. Now there is discoloring on the curled leaves. (green area getting splotchy with yellow). I just fed them 1/4 strength nutes at the end of their third week for the first time using AN connoseur and bud candy. Also changed lights to 12/12 for no other reason than take it easy on the electric bill. They get 1/2 tap and 1/2 RO water ph to 6 (best I can tell with the dye drops method of testing) I am growing in 100% coco in three gallon airpots under 400wt HPS. Please oh please take a look and help her with some advise for this old hippie growing in coco for the first time. Much love in advance for your help! Peace...bongwater.
Sorry, pics aren't better.

might wanna raise your light aways up until she takes off.

N-overdose?
Salt-buildup?
pH-issues?

I have some serious clawing going on to, but on bigger plants. Youll find a post about it at the infirmary on the frontpage...

Please hit me if you find a cure for your plant!

How come 12/12 when they are so young? I was under the impression it should be 24/0 or 18/6 during veg especially that early

I know when I overwater they start to droop and yellow up. maybe let it dry a little and foliar feed to green her up

Consider giving them epsom salts. I'd give 1 teaspoon per gallon. Water 24 hours later with plain water to flush the salts out and next day reload with fresh nutes. Afterwards let them dry out a little as well. Good luck.
