Leaves curling on every plant in CC system

Im using a current culture system 13 gallon in each bucket. I just took a look at everything and found that all my plants are staring to have this weird curl. I first suspected it was nitrogen tox but the leaves are not dark enough green for that in my opinion. My humidity is 65% which is where I usually keep it at, my ppm has been going down over the past 10 days from 290 -> 170 and 170ppm is where it currently sits with a ph of 5.8. My temps at night are 75 F and 78-79 F during the day depending on how hot it was outside that day. My water temps never move from 66 and the water level sits right under the root crown. Ive been in a constant battle with this room where as soon as i fix one thing another thing decides to go wrong. I took these pictures within 5 min of the lights going off. Any help would be appreciated, thanks. image2 (3).JPG image1 (3).JPG image3 (2).JPG

Yea johndoe is right, most people are sitting around 6-8 ppm range in current systems. Id start off with 6 seeing as though you havent been giving them much. I dont have much experience with this type of system. Are you misting the plants at all? Maybe they arent getting enough oxygen Ive never heard of that curling from nutrients. Stress and wind maybe but not nutrients, though you are on the low end. Do you aerate your water?

Jen brings up a good point I was assuming you had some kind of aeration going on as well. It was a odd concept for me at first but your roots need to breath.

I have four air pumps throughout the whole system. I'm switching the water tomorrow. I think the nutrients from low ppm are what's doing it

Let them dry out a bit you have been overwatering wont hurt to let them dryout a bit and start fresh. but like john said dont jump up right away. Plants do very slow processes if you bombard it with a new nutrient even though its what it needs it will shock it. Always slowly adjust plants to things so you can watch the progress

I was gonna have to say this noob is gonna step in and say don't let them dry out! Lol. From what I've seen empty bucket left unattended to results in the ultimate death.

But you make me think of a good thing, get us a shot of your roots let's see how they look. Root rot can look like overwatering some timeS.

Edit: still gonna need to work on upping nutrient levels. Unless you are down to that level becausr you noticed something is off.

Nah man I don't think I'm overwatering if my rdwc system never got over 350 ppm. I think the plants are big enough to take some more food. I'm used to my other nutes but had a bad experience with a bottle so I'm trying something new this round

IMG_2315.JPG IMG_2314.JPG Here's pictures of roots and to show there is air in my buckets. Sorry about the hps yellow on the white roots but I think it's a nite deficiency. It's crazy because I get those aha moments that I figured out the problem but then something like level 2 comes out where it's a new issue, usually small and annoying, but then a new thing. Once I get it dialed in like the others brand I used to run then I'll be smooth. Thanks for all the input.

Those roots look amazing, and its all good. Weve been medicating at least I have, haha. First run in DWC? thats really cool id like to be able to do that eventually, I hear you get massive growth

Nah all I've ever done was dwc and yeah growth is wild when dialed in. I'm probably gonna go back to my old nutes after this. I just got an old bottle and was causing some serious nuts lock up at least I figured that out after realizing many nights of troubleshooting. Normally when something comes in the mail you'd expect it to be fresh

Hello, My first thought is those plants definitely look like an overwatering/not enough air to roots situation, but you're in DWC so how is that possible and your roots look insane amazing. So my next thought is, maybe there is not enough o2 pumping through the system, but again, look at those roots, no slime etc. so my next thought is.. hmmm... could the plants/roots be so monsterous and in vigurous growth mode that they are using up the available o2 faster than it can be replenished? ie DO levels cannot be sustained as before.(?) The roots and their requirements just got so mosterous? -but your super white healthy roots is perplexing if this was the case, if ya know what I mean..

Running nutrients on the low side as you have, I can't see the plants reacting in this way. The plants would pale out and/or get deficiencies if low nutrient was an issue over a few days, in my opinion.

I don't know exact specifics of your system, but maybe set water level in each bucket lower, maybe? just idea..

Good luck.

(edit- other thoughts- check DO levels - add another air pump)

Do you think humidity could cause this? I agree it doesnt look like a deficiency

I've never experienced humidity issues in person before so I don't really know what it would look like. It could be. good thought.

But on another note, I know I read his nutrients are at 170ppm, but it almost looks like what we used to call, 'The claw', nutrient overdose, mainly N. weird.
edit- Actually, looking again, no it doesn't. Disregard claw comment. lol

Its more on the tips than the whole leaf curling like that though, definitely looks like overwatering but his roots are beefcake lol.
