Plants drooping?!

My plants started drooping 4-5 days ago. the roots look alright, a little browning but no rot that I can see. Water temp fluctuates from 66-68 (chiller). PPM is 190 using current culture veg a and b, coco called and hydroguard, PH is 5.8. The only thing I can think of is shock from rising water level? I was leaving for the weekend so I dumped 4 gallons into the system and I did notice them start to droop. That was on Friday, and they slowly kept dropping more and more. The roots aren't completely submerged but can they get shocked by the water level rising a few inches?

Those roots are not healthy. And a PPM of 190? How are you measuring it?

I'm using Apera PH20 meter and HM Digital TDS-EZ from amazon.

I was following the current culture feeding schedule, but when I bumped up the nutrients on week 3 the leaves became dark and leather, which from what I've ready is a symptom of over feeding so I backed off and kept it at around 175-200ppm.

I'm confused about the roots, I'm keeping the water between 66-68 degrees and using hydroguard. I don't know what else there is I could do.

Could the roots be suffering because of me letting the water level drop too low?

Water levels rising might of overwhelmed them lower levels back to where they were originally and add a lil nutes see if there’s a change in those 24 hrs if no change I’d look into it further

I use only Apera meters, so if its properly calibrated I guarantee that's not the problem. Good luck!

I agree with harley , use H202 every 4 days in the res to fix the brown roots. Get the 30% concentrate peroxide at least not the 3% shit from the supermarket.

What Hotrodharley said; your roots are not happy at all. Remember the old Light Bright commercials...your roots should be bright white, bright white.

I read your post literally right after I added H2O2 to the res. I have 34% on hand from my last DWC grow that I did before I got the chiller (major rot problems). Here's an update. I've got some new roots popping out and the lower part of the plant is starting to perk up a lot more.

Bjjislife,
You a Brazilian Ju jitsu guy? I just get curious about why people choose their username.

I think Harley and crew got you straightened out. But I like solving puzzles and would like to add some further info. Based on a theory from a guy whose name I don't recall.

OK, the idea is that the plant tips can be underwater if you allow the upper roots to have air exposure. It's the horticultural idea that Hempy buckets are based on.

So OK, your roots were going bad...but the plant still didn't look that bad...UNTIL you filled up the res to a much higher level. So all those upper roots that were absorbing oxygen were unable to absorb oxygen anymore. And plant that was hanging on with it's toenails...went belly up.

Until you treated the root rot.

That's my explanation for why the problem started when you overfilled the res. It would have started revealing itself later anyway...but would have been much worse.

I thought that might have been the issue. When the water level dropped maybe the roots exposed to air became air roots absorbing oxygen, like in a kratky setup. But after hearing from people here that my roots were not healthy I'm sure it was just a combination of things. Because I've ran kratky before and the roots looked a lot worse and the plants still looked healthy.

UPDATE. the left plant is recovering fast.

I went ahead and made my own "UC roots" (Hypochlorous acid) and started adding it to my system. I've been wanting to try UC roots for a while but after reading up on it and learning that all it is, is a diluted chlorine solution I just made my own. $5 for a pound of pool shock (47% calcium hypochlorite) at my local pool supply and I have enough to make dozens of gallons of it. woot woot

I think that it's possible for the underwater roots to be infected while those in the air remain healthy. I believe root rot is a surface root infection and not systemic. But it's a moot point since you fixed it.
