What is the discolouration telling me?

I am growing a few strains, and all of them are a solid colour of darkish green, but this Blue Critical auto from Dinafem has some odd discolouring that makes me worry something is wrong with her. I'm a total newb. Can anyone tell if something obvious is wrong with this plant based on the weird colour pattern.

Also uploaded a picture of my white widow for comparison

Some seedlings start out goofy

Give her love and a week or so, she will probably pull out of it

What's the soil, water pH, etc

I have been watering with tap water left out in a bucket for 24 hours with airstones to dechlorinate and then phd to 6.5-7

I haven't checked the ph of the soil because I haven't watered to the point of run off and I don't have a soil ph meter.

TBH my ph pen is a cheap one and not that accurate so i aim for water at 6.5ish knowing my pen is off by a few tenths but hopefully still in a reasonable range.

It's about a week later and the new growth seems to be looking a bit better. Still odd colours compared to the other 3 though.

Cool, almost looks variegated. Wouldn’t sweat it still, looks healthy.

Do any foliar applications during lights on?

Thanks,

No foliar applications, at least not intentionally, but I have to admit the blue critical hasn't grown past the top of the pot yet and it's hard not to get water on the leaves.
