So like the title says all my new growth on 2 clones and now my seedlings is very light green really veiny and jus doesnt look the same i tried takin some pics my camera kinda blows any feed back is appreciated...

New growth usually does appear to be lighter in color. There doesn't appear to be anything wrong that i can see from your pictures.
