Seedling/clones yellowing help!

Alright so I have got some clones and some seedlings going. Reason being I'm not a 100% confident on the cloning and don't wanna mess my cycle up. But anyways both are extremely yellow and idk if it too much light for both or too much water!
 
If pics are needed let me know. Also both were sitting I. The window sill with not enough light at first and idk if that could be it and then goin straight to direct light.
 
Well at first they were in plain soil no nutes. And I thought they were lacking nitro for some reason so I added a tid bit and still same as they were. I also changed the soil in the container to a cheap soil from Walmart called Pennington. Yea I kno that ain't helping any but I always do a cheap soil and add my own nutes. But no other than the one time of a quarter strength feed I am just watering with water. Also I changed soil due to it being pure mud
