    If they are outside then they will be too cold and suffering as a result.

    They really shouldn’t be fed yet at this early stage,  they look ok to me,  but don’t feed seedlings.

  • thanks for the replies. they are not outside that was just for the photo. 
    as far as feeding goes all the youtube videos i've seen say start feed with first true leaves. 
  • Too many YouTubers have sponsorship by fertiliser companies...thus recommend using too much fertiliser in lots of videos. They only need feeding once planted out and actively romping away, the compost will have enough nutrition to see them through.

    The potting compost has plenty of fertiliser already in it ... the plants need no more fertiliser until they’re planted in their final spot and are beginning to flower. 

    Feeding before that stage will cause problems.

  • thanks for the Replys. read on another site could be chlorosis and the soil was a bit to compact i thought so i re-potted it and gave it a bit of my worn tea and a few days later all green and rosy again they really took off after that thanks again
