They have turned yellow over time.  It is on more than one cross and not 
every plant in those crosses.  Even the increase is yellow on a couple 
of them.
My suspicion is there is something missing in the soil. I'm actually 
growing in two places.  At my house I'm either growing in a soil/compost 
mix or a soil/sand/compost mix.  The seedlings that I didn't have space 
for in the other location I'm growing in pots.  None of them have turned 
yellow and they are growing well, though not as well as the ones in the 
ground.
In my other location I'm growing in native soil, which is mostly clay.  
My suspicion is the soil is lacking something the plants need.  
Yesterday I watered them with BR-61 and supplemental zinc.  The owner of 
the farm seems to think that is what is missing, because he sprays his 
pecan trees with the zinc.  To me it seems like an iron deficiency but I 
just don't know.

    If only some of the seedlings are like this, but  not that many, then
    it could be genetic. Especially if they have always been yellow.

      If it is named varieties then a different story.  There are different
    patterns of chlorosis (leaves  turning yellow).  A good picture would
    help. Otherwise need a description. Does it start on old leaves or new
    leaves.  Is in veins or between veins? From base out or from center of
    leaves out?

    Also any information on what treatments he has done to soil.

    Each problem has it's own symptoms.

    A friend of mine has a problem with his irises.  He emailed the
    following
    to me.


    "I haven't joined Hort.net yet (maybe I should) and I have a  question
    about my iris seedlings at Wes's. Some of the plants the leaves  are
    almost yellow on the whole plant like I am missing something that  makes
    the chlorophyll. My guess is iron, but I'm not sure. What do I  need
    to add to fix the problem? I'm growing on clay soil here in the
    valley."

    Does anyone have an idea of what is  wrong?
