Is this a N deficiency?

I transferred rooted clones into 5gal pots. In the beginning they were looking very sad, burnt tips and yellowing around the edges. After I started using FF nutes they began to look a little more healthy. This is a before and after pic. But there is still yellowing on the new leaves. I looked at the chart that shows all the deficiencies but i couldnt find one that matches. This is my first grow and im trying to learn as I go.

I think they look great. Leave them be for now. If the entire leaves start yellowing there may be a problem but for now just keep on cruisin

They look good , new growth allways is a little lighter !

Yup .... lookin' pretty good to me

Raise the light or cool down the room.

magnesium deficiency if anything. just feed with cal mag

I usually start with young ones that look like this. They turned out great in the end!
