Yes pure crop 1 once and I think and the day before I took them as cuttings. These are probably 15 days old as cuttings total and rooted maybe 2 days ago.
DWC 1.5 gallon cloner. Do I use bleach or hydrogen peroxide when cuttings are in there

I’ll venture a guess and it’s from what you sprayed.

That'd be my guess also.

How wet do they stay? Looks like rot. I usually get a couple that look like that if I leave them in a dome for too long,

Looking now, did you have them in real humid conditions, then put them in real dry conditions, without acclimating?
Yes kind of under a doom in rock wool, I would have them at high humidity the first 4 days around 90% then I would open the dome up and let the humidity get around 65%..... However when I put them in my dwc cloner setup, they would do the same thing. The humidity would always be around 50% in this setup.
Yes I did that in my dome... However in my dwc cloner setup humidity would always be around 50% bc of no dome.
There were times I spray nothing in my dwc setup with no dome or anything where humidity was around 50% and it did this. Idk maybe I sprayed when lights went off and 6 hours later lights came back on. But I use a small bulb that is like 4 feet away. How can you spray stuff on cuttings without this happening or dunk them in something?

It’s not from spraying.

In hydro I’ve always used Clorox at .25ml/gallon keeps the bad stuff at bay especially if you’re not chilling the res

Looks like rot. Excessive humidity/wetness usually causes it. I usually have a couple do it myself out of 150 or so clones.
Its done it depending on the strain though. I use a dwc cloner where the water shoots up from the bottom of the 1.5 inches of the stem... What can I do about it?? IDK I use to let the very bottom of the stem sit in the water in the DWC cloner. This time I put the water like 4-5 inches below it so the water shoots up on the stems.
Is bleach just as good? Send a amazon link to the pool shock you use and the amount you use.I use diluted pool shock every 3 days in my aero cloner. I never change the water, and get 100% every time....Thanks to @Aeroknow
Well I'm on day 7 of dwc cloner method where the water is like 4-5 inches below the bottom stem and this has not happened yet, although 1 or 2 of the 10 clones I started with damped off or whatever it is... The pic I posted of the flower burning off or whatever is in rockwool, do those black grow cubes (not sure what their called) less likely to get rot than the rockwool?

That foliage rot in the pic isn't cause by the medium (rock wool). I get it on a few clones sometimes, the ones I leave in the dome for a bit after they've rooted, not all of them, maybe 1,2 or 3 out of over 100 usually will get it. I've also gotten it from unrooted cuts and rooted cuts sent in the mail. When the rooted cuts sent in the mail do it, they also always arrive too wet (saturated medium). Since they're mailed in a sealed container the foliage stays wet. How wet or moist does it stay under your dome? If you're getting water droplets on the leaves and domes I would suggest giving them some air frequently and wiping off the inside of the dome.
Should the dome ever have water on it? What should the humidity be in the dome from day 1 til the end of rooting period? I would get water droplets on the dome and they would drip onto the leaves..... LIke I said though in my dwc cloner it has no dome and the humidity is the basement humidity which is 50% and it gets the burnt flower thing too. Maybe when the water was up very high in the dwc cloner toughing the bottom stems it would shoot up into the cloner collar gap and get the stem and leaves wet?? IDK..... Now I lowered the water like 4-6" in it, so water just shoots up to the bottom stems... It is the dewey mister, google it.
When I dunk the rock wool in the water I don't sqeeze the extra water out, so the medium is pretty wet in the beginning or until I open the dome up and lower the humidity.
