Help! Early signs of deficency??

[janedope]

Hey guys, a few of you know me, for those who dont this is my first grow, i have 12 clones growing in organic soil. We fed the girls some N for the first time about a week ago and took some cuts off them. Im now seeing some signs i dont like particularily the curling of the leaf tips and some discoloring... any advice would be GREATLY appreciated....

Rather than deficient, the claw hints at a nitrogen OVERDOSE. Also remember that when you are cloning, adding N immediately before taking cuts is counterproductive to your purposes, as it signals the plant to grow lush foliage, not roots, and can actually slow or prevent rooting.
Try feeding with bloom ferts for a week since you have PLENTY of nitrogen and need the plant to use some of it up. Also, check on your drainage- your soil looks on the wet side.

Also, on top of what Ms.Attic said, a dead giveaway on too much N is that very deep green color.With that soil mix you have, you could just flush with ph'd water and just continue to water w/o feeding up till flower, then dose em with some P-K ferts.
Still, they look as if they are doing well...

Im saying this only because your new to growing, its important that your lighting schedule be consistent. Very consistent.
