Cannabis seedling turning yellow help

Can anyone help me please. 1st grow... 2 plants are 2 and a half weeks old. As you can see yellowing at the bottom... they were in a small pot with rubbish soil.. ive transplanted into these finishing pots with good soil ... growth will be a little slower due to bigger pot i know that. Just wondering are these healthy ? Small for 2 and a half weeks? Whats the yellowish about? "/

Looks good, you may start to prepare nutrients.

Normally, yellowing leaves can mean a few things like nute toxicity or a deficiency or when she's in flower and you purposely stop nutes, she'll get them from the leaves causing them to turn yellow. Have you given them nutrients yet?

I started giving nuts two days ago, looking a little better today i think, my friend said they are small for 2 and half weeks from sprout, these are thier final pots now. Potted with plangron mix from hydro store

How much N did the nutrients you fed them have? Does the growing medium they are in contain any amendments? How much N does that contain if any? Lastly, how much did YOU feed them? This is important to know.

Its 10.6-4.4-1.7
It was no nutrients in the soil i changed it too. And as they are 2 and half weeks it says 5-10 drops per pint but i only put 3 drops in at the moment.

Thats them now, i think they look healthy, they sprouted on 6th september so just under 3 weeks

Just misted the grow room thats why the pictures look funny

They do still have very green and healthy looking new growth so just keep an eye on her and keep a journal of this for future grows, just my opinion.
