Clones turning bright yellow with dying tops.

grapeman,
is it possible you have more nodes on your clones than Stress test? I think you're both right. If you have too much leaf surface area for the size of the stem, the stem can't pull enough water for the leaves to remain turgid. Look at Al B Fuct's clones. If he left all the leaves on his 9" clones, they would certainly wilt.

The amount of water that the stem needs to transport seems to be directly related to air movement, temperature, humidity and light intensity. The amount of water it can transport seems to be directly related to the diameter, the height of the clone and the propagation method.

Just a middle of the road opinion.

Oasis cubes, rinsed and ppresoaked with some PH 5.5 water with clonex nutes. I take the cuts and put the domes on. I adjust the openings on the domes each day after I leave them close to fully closed for the first five days.if the mothers arent that healthy I wouldn't even waste my time taking clones as they would prob not be as vigorous as they should be costing me time waiting for them to root and time waiting for them to get started vegging when they get transplanted.

OGs are notorious for being stubborn to root they usually take me an average of a week extra per tray so it usually takes me 3 weeks to get them banging in the cubes.
They are also sensitive to overwatering and because the roots are slower on the OG it tends to be overwatered more often.
Over watering usually leads to a slow roots and overwatering will usually cause magnesium deficient looking plants. The Ogs are also magnesium hogs. This could be where alot of people go wrong. The Ogs also do not like being rootbound either. Needless to say they're tricky plants but if you take enough cuts of her like anything you'll eventually get the hang of it.

From your pic it looks like it could be phosphorous deficient or magnesium. Seeing as how the plants are so small it's prob not a good idea trying to feed them. Or it could be the leaf temperatures are too high so your getting light burn/bleaching.

The aerocloners are cool and get fast results. Only problem is if you don't sanitize them properly after each use you could end up with a bunch of clones with root rot which is systemic and will probably continue to infect all the cuts you make until you sterilize properly. The pumps sometimes are too strong ( think the 144 site uses a 1200 GPH pump, overkill) so the water tends to get too warm with the pump running 24/7. Either way I'd rather use the room I'd be using for the aerocloners and just do the clone trays and domes. You could prob fit 3x as many cuts. In the same space and then you'd have a lot better of a success rate also.HTH

I usually do 3 nodes. but I do believe you are correct in that all of the above come into play. At least imo.

 

[Stress_test]

I do 3 nodes or 4 or 5 or 6 if I can, hell the bigger the cutting, easier it is to root. But it doesn't matter really, it still applies.

Cutting the leaves is illogical. While there are valid logical reasons for NOT cutting them.

 

[Yes4Prop215]

still havent been able to figure out what this is...its now starting to happen on some new cuts i took...tops only again. totally different tray, i dont think its mold or something. i turned the lights down too....man wtf!!!

. Overwatering for sure, start with stronger clones, try 10-15 ml/g PBPSB in your soak and never look back. I use a 4ft, 6 bulb t5 fixture with only 2 bulbs on for 1-4 trays or kick 4 bulbs on for 8 trays, take domes off once a day for 5-10 min to vent and you should be good to go, way more space efficient than aerocloners. I actually use rockwool but have done oasis the same way with good results as well.

 

[Yes4Prop215]

cool il be cutting back on the watering then, its definately not the perlite because its happening on clones that havent even popped roots yet...also happened to a few sour D clones i just took...turns yellow then white almost then burns. its always on new nodes never on the fan leaves...so i just pinch the nodes off and let them focus on rooting first, they can develope new nodes later..

some of the rooted ones from last week are doing much better after being transplanted and givin the foliar spray..

 

[Guest 150314]

ST, i clone with an aero cloner and without my 4 bulb t5 right above the AeroC the plants would take weeks to clone vs. 4 days.....


y4p215, FOR SURE it is burnt from the bulbs... i can tell becaue of the dead leaf tips (which were more then likely touching the bulbs) the plastic barrier could still be very hot EVEN from the CFLs...

do the clones have roots yet?

I don't think so if the light was close and hot enough to burn a clone it would probably melt the humidity dome, but cfls don't get very hot. I root clones under a 600w and they don't get burnt ever, looks like overwatering. A handy way to keep clone moist in rockwool cubes without overwatering is to use a eye dropper. Once they have a few roots I let the cubes dry out and the roots grow much faster out of the cubes looking for moisture.

I also cut a little square hole in the bottom of my tray so that the runoff can drain out and they don't get to wet.

Yo Yes4Prop215, did you ever work out what was causing this problem? A similar thing has just started happening to me for the first time. I've never had this issue before in years of cloning.

Suddenly growth tips of newly cut clones are going yellow/white after a few days then going brown a few days after that. Only happening to 20% of clones if that.

Temps 75-80F, low lighting (20W CFL 5ft away). Medium is peat and perlite. Never had any issues before.

Peace

 

[moses wellfleet]

I have no clue... Can I still get dished me up some rep?

 

[moses wellfleet]

Seriously though... I am cloning in perlite and I sometimes get those symptoms.

I figured it is from strong light, leaving the clones in high humidity for too long, and possibly not enough ventilation. As the op says it is not a serious problem and cloned always recover.

I don't think it can be too strong light as the last batch of clones were much much closer to the light and this problem did not occur.

Maybe it's a humidity issue but why the discoloured shoots? I'm still getting wilting if the dome is off for more than 10 min or so..

Peace

sounds like some bad cuts to go black ! happened to a few of mine in the end I just threw them not worth all the hassle !

 

[Nifty_PoT]

I had this issue consistently for a few years on an og i had , it got to the point where it was slowing down the clones so much i just said fuck it and threw it away , i think it may of been a boron deficiency as it usually started on the newest leaves and then gets worse. og's can be bitchy like that ive found. I think they need a low level of nutes in the medium while rooting to have the best chance.

 

[BB420]

piff rhys jones does the black tips turn in to brown /black patches as they grow ?

 

[Piff Rhys Jones]

They haven't rooted yet so no new growth. They've been in there about ten days now and I pulled a couple out as the damaged leaves had turned to mush.

The top shoot turns pale almost white gradually, then becomes greyish brown. One went mushy and the other kind of dried up. This has only happened to about 20 percent, 3/15. They're mostly smaller ones. I reckon it is a combination of humidity and some kind of pathogen attacking the weak clones.

Can't figure out why though other than it's the summer. I had 100 percent success in winter and spring.

How are you controlling temperature?

yeaa sound exactly like what i had.. I initially thought that it was a virus expressing its symptoms or some shit lol but i weaned off that idea .
Then i thought it may be a pathogen like u said, i sterilized absolutely everything and it was still the same, the clones just sat there for like a month and eventually they will root and recover but 1-2 months was ridiculous , wish i knew what was causing this as it cost me a great strain :/

 

[BB420]

same here I lost over 10strains wished I knew what it was I thought it might be fungus or something

 

[Piff Rhys Jones]

Not really controlling temps as such, just have them in a room that stays ambient 75-80F day and night.

The bigger ones seem to be rooting nicely now with no brown leaves, it only appears to be the smaller weaker ones that get affected.

It's all good, as long as I take a few more clones than I need, I can afford to lose 20 percent to this mystery illness.

Peace
