Help, Noot problem???

I am experiencing a leaf discoloration problem and don't know what is causing it. My plants are growing very well but a couple of them have leaves that are sort of variegated. They are not yellow or white but sort of gray/green and only half a leaf. Picture a five or seven segment fan leaf. One or two of the leaflets will be half "camo colored" and the other half of the same leaflet is healthy dark green, split down the center vein of the leaflet. Also, some of the affected leaves have curled radially inwards towards the affected half of leaflet, as opposed to curling up or down at the tip. I don't know what could be causing this except maybe a micro noot shortage. I am using ebb and flow with NRS Greenleaves solutions. I used the Grow for veg and am using the Bloom and some Boost in the bud stage. And some of the discolored halves have actually disintegrated or dissolved as they are missing. Not all plants are affected nor all leaves on a plant this way, just some. Also, the problem starts with the new leaves, not from the bottom up like too much or too little noots. Does anybody out there have any suggestions? Also, a couple of my cuttings are exhibiting the same discoloration on a few leaves and they are in soil. What gives? Sorry, I don't post pics. D'oh!

There is a chart full of leaf pics in GROWFAQ , the link is at the top of this page. Go there and find a pics of your leaf.
