Downturned leaves?

Hi everyone-

Before I got my meters it turned out I was running my nutes way high and I was seeing a little burn. I got my meters and adjusted my nutes way down to 650 ppm (complete water change out).

The plants took a great growth but now a few days later and this is all of a sudden happening.

Am I missing nutes? Still to high? What is it?

I'm only now just learning hydro myself but first, check your roots- are they white or brown?
Cover that other hole in the res! The roots are probably JUST getting to the point now where they are poking out of the medium and you don't want them exposed to light.
They look hungry too. While you are fixing the other stuff, hit them with a foliar feed of a complete grow fert with 1/2 teaspoon per gallon epsom salts added to it if you have any kicking around.

The hole is totally covered, that was open just as I was testing the nutes. The roots themselves are white, BUT, they have like a brown on them but I was pretty sure that was from the nutes I was previously using which was brown and sludgy. The water is pretty fresh and looks clean (I don't see green algae or anything).

How much do you foliar feed it?

Thanks.

just bumping this up because these plants are not looking great.

maybe just a few enviroment tweaks. check rockwool ph.

i had 2 soil clones before that looked 5X that bad for over a week before finally taking off...
