I’m not sure why ONE is wilting when the rest have plenty of turgor. I’ve examined the roots and it only appears stained, nothing slimy looking or smelly. I have further topped off, and added UC Roots as preventative if the dreaded rot is starting to show
Ph 6.3
Ppm 900
Water temp 71
Is that a aerocloner or a small top feed hydro setup?
If aero…you check all your misters to see if they are spraying properly…they tend to get clogged all the time!
Just by looking at the color…looks to be on the dry side…also looks to be on the verge of Pythium(Root Rot)
When’s the last time you did a full clean out on the system?
EDIT: On a good note you can see fresh white new roots growing!
It’s RDWC. The emitters are clear, so no problem there. Besides the root mass sits in water
Before I started first week of flowering from veg, I drain the entire res, fill partially and drain sediment at the bottom, repeat until water is clear, then refill w new nutes.
I’ve had it on 6 feeding at 10 mins, thinking it may be too much I’ve reduced it to 4 now
Yes, that’s what I suspect is starting. That’s why I’ve added UC roots now so it doesn’t spread. Other than that, I’m baffled.
It’s hard to see in the pic but what do the roots look like coming out of the net pot?
I hate to even say it but I think you already have one of the versions of Pythium…I don’t think Pythium Blight…which is good as is the worst of the 3 and almost impossible to get rid of…and systemic!
But wilting is a very common side effect of Pythium!
Fusarium wilt?
I don’t see any signs or symptoms such as chlorosis, necrosis, or premature leaf drop which are a indication of Fusarium Wilt…but I wouldn’t rule out quite yet…but not likely

Yeah you are right, leaves don’t match at all. I got fooled by the base of the stem looking dark and mushy.
Back in the day(15-20 years ago)some friend’s and I grew in the custom made, hybrid DWC/Sprinkler systems…long story short one of my friend’s got Pythium a few time’s…what we used back then was a product called Subdue Maxx from Dow…it even worked on Pythium Blight! Didn’t get rid of it but would manage the disease enough to finish a crop…
Then intensive cleaning! Pythium Blight is systemic so in every cell of the plant…imagine cleaning everything top to bottom just to miss a tiny little piece of leaf that finds it’s way back into your res and re-contaminates the grow once again!! Seen it happen…
These day’s I wouldn’t use Subdue Maxx as contains some nasty stuff…TBH I’m not even sure a safe product to use…I’m guessing there are a few ones to be found though.
Not saying you have Pythium Blight…but might have one of the lesser forms of it…something you definitely want to keep an eye on my friend!

I agree with @Alaskagrown .
Are you using any hydroguard or southern ag?
( beneficial bacteria)
@Alaskagrown Oh yes, I cleaned w vinegar and h202 after last use. I knew going into this kind of growing I had to have a strong fungicide. It would be stupid not to. I also have Organcide too, but I believe UC is stronger. In effect it’s plant safe bleach. As for the roots at the cup, it’s two thick tap extending down, yes stained from nutes, but nothing funky looking or smelling. I’ll take closer pics later. As you noted, there’s tip growth but it has slowed. Also not mushy or soft, so still fibrous. Perhaps early stage before that happens, thus UC roots treatment to get in check. If necessary I’ll remove it, but I’m hoping early treatment allows recovery and prevention of spreading
@Hydro921 since I’m running mostly organic hydro, I haven’t prior to noticing wilt. I did use Microbe brew Now I have 45ml to 15 gall res of UC roots. I’ve been reading more. I take it the UC roots can sterilize the water, but removes bennies. I guess this is where Hydroguard comes in ? I don’t have on hand, but that and Liquid Karma has been ordered. I take it Hydroguard can restore colonization of microbes ?
Well it’s gone. It was bent way over and drying out. Leaves getting crispy. Under the cup, bits of soft roots. I’m thinking 6 top watering were too much even though short at 10 mins OR suffocated by the larger roots. The rest are still fine w praying leaves, so if it’s one loss, better than the whole crop going to shit
I wont claim to be an expert on this but hydroguard replenishes. Some use southern ag saying it’s the same but cheaper but I havent done the research.
I add hydroguard every time I add to the rez and have never had root problems. I was thinking in the pic they look more brown than I would like.
Let’s ask @Esrgood4u
You obviously don’t want to use anything that creates a sterile environment while running beneficial bacteria in a rdwc system. Beneficial bacteria in hydroponics doesn’t multiply like they do in soil but they do thrive well and will keep root rot at bay.
Water temperature is massively important while running a rdwc system so I’m my opinion a chiller is needed 100% to keep the solution at 18 - 20c.
Personally I run a chiller and Dutch pro keep it clean so my system is sterile.
Running a large air pump so there is plenty of oxygen in the water is a must also.
Thanks @Esrgood4u
Classic root rot.
Change the solution, sterilize, and cool down the reservoir.
I recommend adding bleach or another sterilizing agent to your water as a preventative measure, especially if you’re having trouble keeping it nice and cool. Frozen bottles of water in the reservoir between now and time you get the chiller are a good option.
Your welcome bro. I learned this lesson the hard way personally and it was a PITA to get back in order. Hopefully the issue gets resolved quickly 
I find it funny @vernal rot only struck one plant though, the rest seem fine, but I’m not going on that basis now. I’m going on the basis the whole root zone is endangered. Even at 71, I’ve dropped under 68 (67.2) and yeah the merry go around of ice packs isn’t stopping to keep cool. I’ve already looked into chillers, and I don’t have anywhere to hook it up and too expensive, so I have to settle for ice pack rotation as the best alternative. Yes that’s what UC roots is BLEACH, just plant safe formulated, so sterilization has been done at 5ml for 15 gall.
Then you’ve done all you can do. I’d just consider yourself lucky it only got one plant. A lot of people swear by UC roots, just bleach is so much cheaper and does the same thing.
IDK what else it could be. Sudden wilting like that from an otherwise healthy plant…there’s really only one likely culprit. Fusarium or root rot, and it’s rarely fusarium. Especially in winter indoors with no other plants around. Are these clones or seed plants?
Yes I will consider myself lucky if I got the rot very early before taking foothold in res. Again, no smell or slime, so it was stealthy and very fast to kill. I’ve tossed the rocks too. Will wash basket in bleach solution. I did research on the fungicide to have on hand for whenever, and I decided this was best. Also yeah I know it’s similar, just feel safer using a plant safe formula. I think I started to have this when I was beginning in a smaller DWC, and rushed for the h202, didn’t realize it was too much, almost lost every young plant to immediate wilt I’m smoking now and have as mothers. I think household products are best to use when you’ve done it regularly, otherwise it’s unfamiliar and guesswork by ratio, that’s why I opted for a safer but costly product. All clones. I guess all I can do now is keep watch and the water chilled. Thanks everyone, I appreciate the help offered 
This has been my “go to” for any kind of water culture growing…works flawlessly in my aero systems!
It’s concentrated barley straw extract…it creates a bacteria that itself creates enzymes that consume organic matter.
Extremely concentrated, organic, and safe for all plant and animal life! Oh and cheap!!
Also keeping water temps under 70 is pretty important…
