Odd color growth on clone????

[CannabisTHC]

Alright heres some clones that I took 12 days ago. I have clones in Rapid Rooters as well as a DIY Aero-cloner. I can't figure out why I keep getting this growth that is greyish black. I've been having this problem the last 3 times I've cloned. I thought it was the humidity dome last time on my rapid rooters that caused this, so decided not to use it this time. But I also get this same growth on some of my clones in the aero-cloner.

Never really seen any pictures of something like this in the past 8 years of being on forums and growing. They will start to get this problem and slowly die. Some clones will root and not get this problem.

RH: 40%
Temp: 72

Aerocloner is on 24/7 water temp has been 70.

RR water them everyday or every other day depending on how moist the cube is. Make sure its not soaking. Heat mat set at 75.

Been using well water (125ppm) on all clones.

Light: 2, 23 watt cfl's a foot away.


Thanks for any help!!

When the tips fade their nice green color it usually means you've overferted. But don't know what to say about clones.

Can you fill out the questions below?
NUte burn does not affect newer growth, it's older growth first.....

when leaves come out disformed like this there is a few things that come to mine with your situation....

micronutrient problem, light being too close.... pathogens since your using cfl's they would have to be extremely close to get this problem.....

Can you get a little more of a closeup of the problem?

HYDROPONICS/Aero Ponics/Coco/Soiless/

Been there done that....

You will definitely get better response if YOU take the time to fill these simple Q?S as being you have a very low post count and people won't help if you do read the sticky and do your part...

That being said I'm going to go out on a very short limb here and say you have a mold growth problem that is tied in to your environment...

I say getting too cold and humid at night. Now mold is worst then any pest. IMOP. Prevention and environment control is key here. First fix environment. Second remove any infected areas ( whole plant if can would allow to start clean!)

Now after fighting the good fight myself and helping other for years (and a LOT of credit is Hidden in IC mag. lol) , have come up with a really good mix to fight PM , mold, BOTRYTIS..... ( never ever buy a used AC..... lol) to BEAT them all.


Do major damage removal.

First spray with Zone 10mill per gall and penetrator 60 mill per gallon.

The Zone is basically chloramine and it will kill all activity on the surface. People have gotten good results just using this but IMOP is just waiting with the door open for an easy Re-evasion ( you are warned....)


Then NEXT DAY spray with a 1:3 or Aquasheild/Hydroguard : water ratio YES WAY over recommend dosage.

JMS-Stylet oil 4 tablespoons per gallon.

60 mill gallon penetrator.

So , in my pump sprayer I'll mix 250 mill Aquasheild, 750 mill water, 15 mill JMS-Stylet oil and 15 mill penetrator. ( this is close to a commercial regime )

YOU must keep shaking your mix as the oil and water will want to separate. Turn nozzle to fine mist .( must be some sort of pressure spayer, they got small ones for 10$)

Treat early in day once a week.

Any Q's

Can you fill out the questions below?
NUte burn does not affect newer growth, it's older growth first.....

Really? ALWAYS? From your guide...

"Now for having too much nitrogen in your growing mediums or soil. .... [snip] Leaves can be twisted when growing… mainly new growths."

I too notice it affecting new growth.

If I had to guess the plants pictured are hungry. 125ppm? Time to start feeding. They are showing various micro-nutrient deficiencies. Keep in mind clones are "fully mature" and require a bit of nutes.

 

[reckon]

the brown color is rot or mold

they are too wet, and somehow the humidity is higher than your posted 40%,...what kind of hygrometer are you using?

that's from what I saw in the pics

honest easy question, and a simple answer

Thanks for all the replies!

Yeah not the case here.

Thanks for the advice, I don't feel like I need to fill that out since I gave you all the info that is needed. Maybe I would get a better response but thanks anyway.

Only part I missed was there isn't any ventilation in this room or fans going and there are some gnats. Which I thought maybe they caused a pathogen. Doubt its a micronutrient problem considering I've never fed clones for the 8 years that I've been cloning. I am adding Olivia's cloning liquid after 5-7 days. PH'd water. Light definitely isn't too close. These clones are affected sporadically. RR=Rapid Rooters.

Thanks for the info I'll keep that in mind.

Thanks for the response but thats not the problem. These are clones without roots they don't need nutrients yet. Theres the possibility that a low dose of macro and micro nutes would help root them faster but from my experience straight water works better. Obviously with the 125 ppm there is some micro nutes in the water though.

Thanks for the answer, I think you and W.P. could be right, although not sure how considering I have such low humidity, I know for a fact that the room is 40% humidity (Live in a very dry climate).

I thought I was feeding my RR too much so I let them sit one day longer, seemed to dry out too much if they go one day longer though.

But that wouldn't explain the aerocloner's results. I never foliar spray the plants fyi.

"These are clones without roots they don't need nutrients yet"

If you filled out the forms people wouldn't have to play guessing games ;-)

Honestly it looks like heat, but who knows. Looks like the lights burnt the crap out of em or something man. Fill out the forms and see if you get better help.. (hint hint)

Clones dont just look like that unless you overnute them, or fuck them up somehow like too much light. If its too soggy itll just usually never root. Too dry it'll just wilt. I'd say maybe the "RR" was pre-charged with something? Try rooting in some perlite for a control?

 

[CannabisTHC]

Already got it figured out thanks though. Honestly its not really a guessing game, theres two people that have confirmed what I have in this thread. A few other experienced growers outside IC said the same thing.

Its Botrytis (rot), need more airflow in the room as well as make sure no dead leaves, the room probably got too hot at some time and the medium was probably a bit too moist, I should squeeze the cubes to get a bit of the moisture out. Some probably got air bubbles in the stem as well. If I let the Rapid Rooters go 2 days without watering they get too dry so I guess they're too wet from everyday watering which does make sense. I had better luck with Rapid Rooters in another location.

I think I'm going to go back to a bubble cloner they're foolproof and been using them for years. I'm going to add a cloning gel as well for sterility purposes as well as keeping the air bubble out.

I love how cloning has all of a sudden become complicated after being able to previously root cuttings in a cup of water. Will never stop learning.

BTW I did get a bunch of these plants to root, just lost a few as well.

 

[bergerbuddy]

Warm up things.... spray em a few times with a good fert mix PH'd TO 5.6... new growth should green up... If these don't have roots and have turned this way since cloning.. then yup you do have a fungus attackin

Cann, how do you know this is rot? Where did you find this at and how?

MynameStitch Cann, how do you know this is rot? Where did you find this at and how?

Because I told him so lol lol.... J/K!

I needed about .5 seconds with one of those pics before I knew EXACTLY what was happening.....

Ps follow the recipe above.... ( you can cut out the zone step if really low on $$$....) , had the worst case of botrytis ever, seen too many keeper moms infected had too save them...... Many, Many remedies tried most were very ineffective. This one is GOLD.
