White widow clones turning yellow

Can someone help me out and tell me whats wrong with these clones? They all seem to be turning light green.

how long has it been since you tryd to root them?,iv notived some strains yellow more than others, but that kinds looks like new growth

There are too many factors to say what is happening without more info. They look massively underfed to me.

they look pretty nice to me, maybe a little pale green, but still, i would just keep the good N flow in, whatever is that u use

I'm using grow big from fox farms. They've been rooted for a week an I was just apprehensive on feeding them full feedings. It's my first time cloning so I am getting the feel. Thanks for all the help!

I like to hit my cuts with full strength grow big (1tsp) I personally have no burn problems, and I also Do a tbls bigbloom(should pick some up it's amazing)
