Browning on cutting

[Norkali]

*The cause has been found. Lack of light. Every cut returned to normal and rooted after it was placed under more light.*

Okay, this is a new round of cuts. I have dialed in the temps and environment the best that I can, on a mat and they hover from 73-78F throughout the day and night, along with raising the humidity dome a couple times a day to exchange fresh air. These are about a week along from cutting, and yesterday I was only able to lift the dome once - sure enough browning started.

I dipped these into a solution of 1:100 bleach/water solution and isolated them. The question is, has anybody found a cure for the browning on a cut like this? Look close for the browning, it's there.

this guy has somewhat the same problem...

only you seem to have a PH problem going...

 

[Norkali]

Thanks Core. My pH was at 6.3, (Which reminds me, what is the optimal pH for Rapid Rooters, 5.8 or 6.5?) the twisting was from the black/brown spots, the tissue gets soft and gooey.

I've misted with a solution of h2o2 and r/o water, mold taking hold of a few more cuts. Should I continue with the h2o2 spray, or go with something else?

it looks like they are dying up to me. this happens to my cutting also, after they have been transplanted. For me it clears up after a couple days. i ph my rooters at 6.0 and keep about a 3/8 of inch of water in the tray. hope this helps

Where did this clone come from? It looks like phosphorus from cold temps or very slow rooting times, I also agree with Core about the pH as well, the curling leaves are from improper pH/heat

could be caused by those, but I would go with pH.
Core! It's so nice to see ya again! I been away for a long time
It really stinks being sick and you can't get stuff done you want too.

Too wet & too warm. Or too cold.
Whatever the case,that cutting is All Done,toss it out.
Always clone 120% of what you need,that way there's room for these things to happen.

Cheers!

 

[Norkali]

Thanks much everybody. I tossed that clone later that day, along with about 8 others. Stitch, that cutting came from a mom who had been experiencing a little neglect, so your probably right about that. This tray had to go without a heating mat, so you guys are right on the mark I guess, they dipped down to 60° at times.

Is there a chance on saving any cuts that have a slight amount of browning? Perhaps use a 1/100 bleach solution as suggested in another thread?

 

[Norkali]

Bump. That whole tray ended up going in the bin. Now, some other cuts are showing the same thing, no twisting but some browning, before I spray anything - 1/100 bleach solution, good idea or not?

I'm still having that very same problem. I lost ALOT of cuts.
Heres the thing, alot of folks say its ph but I have never ph'd my water before and i had no problems.
Currently i put my clones in a cup of water to root. But i had the same problem when i tried cloning in coco and when i use my (Botanicare) power cloner.
I'm clueless as to wtf happened but REZ gave solid advise, take extra clones cause ya never know how many wont make it.
I took 40 cuts of a Mango/Widow mom and only 3 are still alive. The rest looked like yours.
Sorry i cant help, just wanted you to know you're not alone. Peace...Evl

Thanks Rez Very sound advice.

I used to have 100% success in my old setup. I'm still working on dialing in my cloning at this new location. Current success rate is about 30% right now. ROTFL!

Cold temps will warrent off clones from rooting and therefore the plant feeds off itself, the purple brown you see is due to cold temps, yes as long as your plants are not affected by mold/mildew you can keep them.


You have to get them warm and keep warm and slightly high humidity depending on your cloning method.....

 

[Norkali]

Bump again. Thanks for the advice guys, I've managed to get a good amount to pull through now. I'm thinking the environment was too warm as well, I put the trays directly on top of the mats, now the are elevated slightly on a towel.

My question is, has anybody managed to get rid of the browning on a cutting once it has started, or should I just throw them out and save the rest?

 

[Norkali]

To the top!

This happens to me when I use Rapid Rooters. If the humidity is too high (temps too), that shit spreads like wildfire. The clones will snap out of it as long as you have a healthy node or two. Once they start vegging that browning will dry up and the plant will drop the leaf.

 

[Norkali]

If anybody has problems with clones 'browning out' it is due to a lack of light!

If anybody has problems with clones 'browning out' it is due to a lack of light!

Cuttings yellowing off is usually caused by TOO MUCH light intensity.
Too close to the lights causes the cutting to spend precious energy trying to do photosynthesis,
which in turn causes it to translocate mobile nutes (stored away N and other mobile elements) from it's oldest or largest foliage.


Many many things can cause cuttings to fail to root, but yellowing off on unrooted cuttings is not caused by a lack of light.

 

[Norkali]

The cuttings were not yellowing off though; they were turning mushy and brown/gray, then eventually slimy. This is not to disagree with your point though, I agree too much light can be just as deadly.

My first time cloning (C99) I had a 100% success rate with a regular fluorescent above them, I ended up having more clones than I knew what to do with. After that, I tried to use the light from a 600W MH that was ten or so feet away, not very intense at all because of the angle as well - 3-4 trays (separate attempts) worth of clones had maybe a 3-5% success rate, and even those had this brown/black mush. Here's what tipped me off, once I took any of those clones that showed roots and put them under more direct light, the brown seemed to 'dry up' and the cuts resumed normal growth. Here's a picture of one that this happened to:

Now that I am putting my cuts under more direct light I have RAPIDLY approached a near 100% success rate again. Edit: I tried everything I could think of to try to fix the problem before putting them under more light; one at a time in an attempt to fix the problem: dialing in temps/humidity, using Serenade, using Subculture via foliar spray, not spraying anything, you name it.
