having some yellowing

[tnbuds]

I really appreciate all the help i have gotten from you guys on here. I have a new question now lol. I have 46 plants under 1000 watt mh 8 of these are showing yellowing starting from new growth and it goes from there and makes its way up the leaf from inside out. I checked ph and it's neutral, checked npk and they are all good except low potash i just transplanted them 5 days ago but those kinda started that a lil before the transplant. they are only 2 weeks old right now but looking good except the ones i am asking about. i am using soil less mix and transplanted from jiffy peat pellets. thank you to all that read and reply.

Could be a lack of Nitrogen but hard to tell without pictures.
