Looking at the fading green between the veins I would say the guys are right in she is a little hungry so start the light feed today with extra Calmag, she looks like a ten day old plant already so I imagine she has used up the soil nutrients that are close to the roots. She will be a big plant bro I can tell.

I started a light feed 2 days ago so hopefully it will be an improvement! Im using 1ml of calmag atm how much more shall I bump it up to 2ml all the way through? And will that sort the rust spots out? They look good for their ages! 11 days today

I would stay at 1ml for now,she is growing well so I wouldn't worry to much.
