HELP! Is this a light issue or a nutrient issue? Or both?

[Ags98]

I’m noticing disolcoration in both plants. Left has darker green splotches on the leaves whereas the right-side plant has yellowing around the edges. I’ve done research on this but my plants seemingly fall into a few categories and I can’t decide which problem it is. Because of the HPS light it’s hard to see the yellowing around the edges of the right-side plant so hopefully that doesn’t affect helping.

setup is:
1x autoflower northern lights (right)
1x autoflower blueberry (left)
sun sustem 150w HPS
bedroom humidifier
table fan
clip on fan
soil: foxfarm ocean forest
current nutrients: fox farm 1x/week 6-4-4 (either grow big or big bloom, can’t remember right now I’m not home posting this)

Right off the bat I can tell you that they are not liking the solution combo your feeding if your feeding bloom? Autos don't take full feeds right off the bat.

So just hold off nutrients until flowering or later in vegetative, only water every 2-3 days or when dry to the touch 1in down?

They are too young to feed them with nutes.
normally with autos you almost have enough nutrients in the soil to get past the first 2-4 weeks.
I know it’s tempting to just feed it right away, but I would wait a little bit.
I think it’s nute burn also as budgal is suggesting

Okay thank you guys for the help! I will hold off on nutrients and keep to just a regular watering schedule!
