Oxy Cloner Roots going Brown

I been running a oxy cloner 20 site for over a year now with a water chiller and 2 air pumps with one big 4 inch air stone and 2 smaller ones..Between each use i clean with alcohol and circulate bleach for 24 hours then circulate hot water with dish soap, then rinse and run it again...I change the water and ph every 4 days...

Couple days ago I notice the later rooted clones have brown roots, so I circulated bleach for couple minutes, then hot water with soap and rinsed and steralize with alcohol and put back my tray, also changed my small air stones to new ones, kept the 4 inch..

Why am I getting brown roots? The first rooted clones already planted had white roots... I chill at 78 degrees and found this the ideal temp after running continous clones for 12 months with no problems...

I also use clear rez, my air tubing dont even have any slime at all

Ideas?

Look to the mother plant where they came from. Is the donor plant unhealthy? Has it got a Thrips infestation you haven't noticed yet? The leaves would have little yellowish speckles on them.

No perfect mothers, 18 different mothers

I emergency steralized the cloner yesterday and planted most clones with brown roots

No thrips where im from

Are you running anything constantly to keep your roots healthy like bennies or some kind of hypochlorite?

Clone X 10ml in 2 gallon water/rez clear thats it, been running fine with white roots for a year, hundreds of clones, only now running into brown roots...The first 13 clones of this recent batch was white, the last couple days turned brown..no slime

That's weird man.

probably that the air n contact to your roots is too dry .. not containing enough humidity so roots dry out and get brown

Are you using city water or RO? If city you might have just gotten some shit blooming in the water supply.
Is your Resclear old? I love me some hypochlorus acid but it does have a shelf life.
I use UC roots (same thing as Clear Res or whatever its called) in the seedling tray, works awesome for rockwool but I have not had luck with it in rdwc.

no wonder why everybody says French weed is the worst on the planet.
@kingromano the air is too dry? LMAO.

Lol...

I did turn down my temp to 75 as theres a 3 degree differnetial before the cooler kicks in and will see, going to change my cooler tubing tomorrow, new clones shooting white roots thus far...No city water im from the islands up the mountain, no dry air up here haha, pure fresh water here...

Lower temp plus cold weather and all white roots, of course grows slower in colder water

78 is too high. Anything above 74-75 and root rot can start (if there’s not enough oxygen). I always keep my temps at 70 or below (usually more like 65-69, though this is for grow+bloom, not cloning. I just use an aero cloner).

Edit - also, have you ever replaced the air stone? Or have you been using the same one for a year? I’d recommend replacing the air stone if you haven’t yet. They can harbor some funky stuff, especially if not disinfected properly.

Wouldn’t hurt to add a bit of h2o2 as well.

No slime? Have you had the brown slime before? Is your ph spiking (high)?

Ummm all issues are resolved...Colder temps no bacteria but twice as long to root

I run my cloner unchilled. It stays at least 80F sometimes higher and I dont change the water until they leave it.
1-2ml of southern ag has kept it clean and I pop the lid every other day or so for fresh air. No issues yet.
If what you were doing worked for a year, i doubt you need to change anything. Just some bad luck with something getting introduced into it by accident imo.
Glad you saved this batch though!
