Help please, not sure what's quite wrong?

[earthling420]

Not quite sure what's wrong. My temps are 75f with rh at 55-60%. I have exhaust running nonstop with passive intake. Strains are feminized critical and feminized chocolope. Watered 2 days ago with ppm solution of 650 my base formula is grow micro bloom by AN. They are 3 weeks into veg with a medium of perlite and ff light warrior with some ffof at the bottom only. Any feedback is appreciated! Thanks!

whats the issue?

The browning on the edges of the lower leaves. And I thought that all the leaves should be sticking straight out for proper transpiration.
Like I said, not totally sure what's wrong, I just know the browning on the leaf tips aren't good.

If it is...it's extremely mild and early. Just back off nutes a smidge.

I use ro water

Thanks everyone, I was thinking nute burn, but it looked dif from typical nute burn. Then i thought deficiency. I think it might be from under waterering previously, too low of hum previously, when I accidentally sprayed hard tap water on them, light being too close, spraying ro water under 5w led turned on or a mixture of all of these and then some lol

But if you guys say they're fine, it's on you lol

BTW I raised light as well to 3' just in case, gonna try and find that sweet spot
