New growth yellow - slow growth

I was given this clone (pic1) about 3 weeks ago , I was told it’s either black sherbet or some kind of kush so not sure myself what it is . The clone was in soil about a 1.5litre pot, I transplanted it into a 3litre air pot using canna coco coir . I did not try to remove any soil from the roots . I gave it a watering with canna nutes 1ml/litre a&b ,1ml Rhizotonic and 1ml calmag , ph 5.9 and ec 1.2 .
after a few days I topped it and stared training . .its been about 3 weeks it has grown but all the new growth is very pale yellow colour . I have other young plants in there that are fine so it’s not my light . I’m using mars ts 1000 and my tent is 100x50 . I knew it would go through stress but it really seems to be growing slow and weird . Is it to much nutes? should I flush or let it do it’s thing ? Any suggestions ?E13F1BB4-A4F2-426B-8982-96EC9B09E11F.jpeg

Are u watering/feeding daily in the Coco
No not everyday only when the pot feels light usually about 2-3 days now . I did forget to say I flushed it with just water ph5.9 and a few days later I feed with nutes but put a lot through and checked my ec and ph run off they both cane out just .1 under what I put in .im thinking iron deficiency as it’s the new growth that’s is starting to yellow first
 
Never let Coco dry out, ever

Feed daily till runoff with 1/4 strength nutes


Thus her slow growth and unwell look
Ok I will give that a try , could it possibly be not enough nutes only been giving them 1mlper litre canna a&b , Rhizotonic, Cannazym and calmag that is about half cannas light feeding schedule .

Coco should be fed at least once per day to run off with a pH around 6.0.
Never plain water.
Never let it get dry.

Would you say that for the first stage of veg aswell as I find from seed to about 21 days they only need a little watering about every 3-5 days . Also I germinated these 3 seeds in pic below same time I started all off them on 2ml per litre of Rhizotonic and ph 5.9 then after about a week I feed 2 of them 1/4 strength nutes and 1 I just kept it with the Rhizotonic, the one that has had no nutes apart from Rhizotonic is doing far better . I will definitely be holding back on nutes till atleast a week in future 2E0B1ACC-65F3-4C0C-A864-A37814FC66C7.jpeg

How old are the seedlings in the pic you posted?
 
Dude


Do what u want, but you have issues, because your treating coco like soil

Listen or don't, yer call
I’ve never used soil in my life I’ve always used coco but grown from seed and never have major problems .this was a clone that was in soil and since transfer it’s not liked it so was just asking opinions in what the issue could be and how to possible fix it .

I start in 1 ltr air pots. I feed daily to run off starting about day 3 from sprout.
Daily feeding to run off replenishes the nutes, pulls in fresh oxygen to the roots, and prevents salt build up.
