Just started to notice that the colouring of one of my girls is off could anyone shed some light on this for me? Any thoughts are appreciated.
Could anyone explain the colouring of this seedling? Promix Soiless mix no nutes just pHed water so far: White Widow autoflower germinated July 27

It's too early to tell but looks like that seedling has TMV (Tobacco Mosaic Virus). It's too early to be a nutrient deficiency. It's possible it's just some abnormal discoloration that she'll grow out of, but does look like TMV. Who was the breeder? And, are you a smoker? Smokers should always wash their hands before handling seedlings, but more likely, the breeder had some infected stock which got passed down to the seeds.

I’m not a smoker and the seeds are from Crop King Seeds . I germed in a peat puck and used tweezers to put the seed into medium
NOTE: In looking at that pic again, it appears there's another seedling next to it. Be VERY careful of that possibly infected seedling. If it is TMV, it can spread to the other plants, so if you think it is, you may want to toss it ASAP! 
Sounds like you did everything right. Crop King, I believe is only the distributor and not the breeder. That being said, it's always possible the seed got handled by a smoker before it made it to you, or it was already in the genetics. Again, that's assuming TMV is the correct diagnosis, but if you do your own research, you'll see it looks like it! What is the strain of seeds and who's strain?

It’s white widow and I’m not sure as to the Breeder. I’m assuming it’s one of their quality ones from CKS. That being said I will keep a very close eye on it and see what the next set of leaves does when they come in. I have read about TMV and how I can spread since they are all babies I havnt touched any of them yet and won’t proceed to until I determine what this discoloured portion May be. Thank you @Mr. Krip

@Dutchman1990 what is the pH of the water you are using? Before I bought my pH meter, I watered my seedlings with I later learned was 7.5+ pH tapwater and had similar results.
I agree with the ph issue. Check that out. I would keep an eye on it. It may grow out of it.
Guys, you're both correct that PH is important, but it's important so the plant doesn't get "locked out" of any nutrients and develop nutrient deficiencies. That seedling is much too young to have nutrient lockout. It barely has roots and is still living off the nutrients in the cotyledons. That issue is not caused by PH or any nutrient deficiency, IMHO!

Hey guys it turns out the PH was high in my watering can and soil it came in at 7.8!!! So I dropped and lowered it to 6.4 so hopefully that cures any issues !! I’ll keep it updated

I’m almost positive it’s and iron deficient due the the high ph value blocking the intake of nutrients ! But I’m a novice so what do I know lol
For either Iron or Magnesium deficiencies, the plant will show yellowing between the veins of the leaves while the leaves themselves stay green (for an iron deficiency, they turn more white!). Your plant is showing yellowing veins with "mottled" leaves. Also, while PH can certainly cause nutrient lockout and is very important to manage (see my What The Good Growers Already Know: Top 5 Lessons For New Growers link in signature!), nutrient lockout occurs over time when the roots are already uptaking nutrients - not typically in young seedlings with new roots. Again, I could be wrong, but I maintain this is not a nutrient deficiency.
This is what an iron deficiency looks like:
This is a magnesium deficiency:
This is TMV:

Yes I’m letting her rest and grow a bit more. I will update tomorrow with new pictures!! Hey second leaves seem less effected

I'd bet it's pH related.

Hey all so thanks for any advice and info this far!! Here is a updated photo now of her second set of leaves coming in. After correcting her water PH on Friday the other 2girls have perked up this one widow has grown but still showing this patterning.
Here she is ! I’m leaning towards TMV now as the second leaves are slightly discoloured as well.
Any further
thoughts and advice are greatly appreciated

My thoughts remain the same, Brother! In my initial response I said it was most likely TMV or some other genetic mutation causing the mottling of the leaves and not a nutrient deficiency, which would be caused if it were PH-related. I also pointed out that the age of the plant indicated that it wasn't even uptaking it nutrients through the roots yet, or had just begun, and was much too early for lockout related to PH.
That being said, I also acknowledged I could be wrong, so, for any of those that really believe it's PH related, I would simply ask, what nutrient do you believe is locked out due to PH and does that type of deficiency match the symptoms displayed?

Yes thank you @Mr. Krip I am a complete novice myself so I’m still trying to research it as much as possible !! I understand it can be given to another plant easily so I’m makig sure not to touch and of them until I confirm to the best of my knowledge of what the problem is. If it is TMV could I just move it outside in a 5G to finish off her remaining life to see if she makes it but keep the rest of the girls safe !? If it’s not worth it then I’ll see if anything changes by weeks end or sadly I’ll have to end her young life.
You could try anything, but nothing is ever guaranteed, although, outdoors would be much safer for your other plants assuming it is TMV.
If it were me, and I didn't have another seed to replace it, I'd just wait until one of the other seedlings has 5-6 nodes, top it, and root the cutting to replace the seedling with TMV. Whatever you replace it with is bound to be better than fighting the battle with TMV. Even if you were able to prevent it from spreading to your other plants, the quality and quantity of the harvest would likely suffer considerably.
