I'd be looking at anything you are doing differently.
New cubes? New anything?
Old anything?
It seems much deeper than a nute issue.

I think you should repost your question with pictures and a filled out nursery form here asap.

did you soak the cubes in ph'd water first ?

I'll attempt to answer the answers in order :

EVERYTHING is being done exactly the same as before. Same rockwool blox, same nutrient, same trays, etc, etc. I do a Ph reading every 2nd day, and they are steady at about 6 to 6.5 .. I have always germinated in a 1/4 strength Dutch Master Grow mix , which gets them started, then up to full strength when roots appear out of the bottom of the blox. This is when I pot them , and they are in a flood / drain setup.
Yes.. the seed is from a homegrown plant which somehow got hit with a male ... maybe a fly or something... the seed is only about 2 year old.

I've always started them off under a 600 watt light ... usually about 12 - 15 " above the blox ...

As of today, ALL the yellow ones have withered and died .. the partly yellowing ones have finally come good and gone green ....so I now have 8 healthy looking little baby's coming along nicely....

I'm NOT computer literate enough to work out how to send photos .. I'm almost 60 yr. old and only startede computers a year or so back.. I will get there one day ( if I don't die first..LOL)

I would just like to express my appreciation to all who replied... it's good to know that people still care enough to want to help an old phart... Thank you all ..

Maybe it was just bad genetics. You probably got a hermie and thats why your plant had seeds. If everything is exactly the same then I would guess its the genetics.

I would go to straight 5.8 water and see what happens. If all are being treated the same, then the only difference is the RW cube or the seed it self. Saying that, your only choice is to remove from existing RW cube and grow in another. You state in your detailed reply "all things the same, the same RW bloc" Do you literally the same RW bloc you grew in already? If so, that might your problem.

You can't change seed genetics, so change what you can. I would first try the water only, no improvement, new container is your only choice. Good luck from one old phart to another. BTW, all the advice I just gave is base on logic alone, not grow expert, but a logical rookie. BH

So you are saying nothing has changed in this grow from the last one except the seeds.

I don't believe it's the seeds.

It took me a while to figure out why sometimes I can clone easily and others its difficult.. I narrowed it down to the time of year I was rooting.. When I rooted (seed or clone) in the summer they grew awesome.. When it was cooler outside it was more difficult.
Anyway my lesson was heat.. Germinating seeds and clones like heat.. they require heat to crack, sprout and grow. But too much heat or too little heat can play a large part in successful growth.
I guess Im suggesting that, even when you do things the same, environmental controls also need to be in the equation. Im guessing your problems have more to do with temperatures then seeds/your germ. practices..
You also mentioned that you used the same trays, Im wondering how they were cleaned? You could also have some sort of algae or other infection causing issues. Having a 600W light 15" above the rockwool is a little excessive for a
How about humidity? Do you know what the RH is in the room? I would invest in a couple floro's and use them for sprouting and vegging.

I say it might help to switch to organic, you cannot burn your plants. I hope you get a great harvest! Also try and find some clones or new seeds, it might be that your seeds suck.

420oz... you can, indeed, burn your plants with organic ferts.... be careful.
