Hi all, currently under way with my first grow with a few CBD Hash feminized. They are currently growing in pots in a cold frame.
Most things are going well but a few things have gone astray which I have a few questions about.
1).I transplanted a seedling when it was tiny and had it's first set of true leaves. The seed was raised in seed raising mix originally, I then transplanted it into a bigger pot with some bunnings potting soil meant for tomatoes & vegies. The plant did not take well to the soil and did not grow at all. It just very slowly started yellowing from the bottom up and one of the leaves ended up looking twisted (please refer to picture 1 attached). What could be the cause of this? I noticed the soil I planted in had a lot of wood chips in it as you can see in the picture... Does not look like an airy/light soil as i'm told soil should be for cannabis

Could the soil be to heavy for a plant, especially such a young plant? Or could it be in relation to the plant being exposed to fertilizer/nutrients to early on ie, I should of waited longer to transplant?
I also transplanted another plant in the same soil but this time I made a decent portion of the soil seed starting mix then more towards the bottom or 2/3 of the pot, I potted the fertilized potting soil so the plant can grow into. That plant is definitely doing better but it is starting to show early signs of the slight yellowing the plant in the picture has.
It can't be a lack of nutrients can it? All my other plants have been growing happily in seed starting mix which I'm told don't hold to many nutrients and they have all done much better than the plants I've potted into the tomatoe potting mix.
If I was to do it all again, I would've planted in seed starting mix and waited for the plant to be about the same size as the second, then transplanted it into a bigger container with 50/50 organic potting soil and perlite. Would that have been the correct move?
To note, I have not been fertilizing, only some a small amount of seasol every 2 weeks or so.
2) In picture 2 here, I have my largest plant, If you can see the picture is this early signs of iron deficiency? Maybe it can't be seen so well in the pic but in natural light the top leaves seem have a darker green in the veins. Thoughts?

3) They have not really been exposed to any direct like as they've been in a cold frame for their life. Would it be wise to harden them off slowly and open the door of the cold frame to get some direct light in there?
The cold frame was to hide the plants from neighbors and it will still do that if the doors open. Would this be better for growth?
I always have so many questions relating to the process and am trying to learn as much as I can so my future grows can be of better quality so any help provided is greatly appreciated.
