Snips didn’t open and had some kind of moldy crap.

[daleharris]

This is one I have not seen before, I received some cuts from a known and trusted source and they arrived in good shape I thought. The snips were wrapped with a paper towel around the roots of the cuts, they were in a bunch together, and as soon as they arrived they went into a glass of water/clonex solution same as the rapid rooters which is the normal way around here and always works. I was short on time and trimmed the leaves of each one individually and trimmed stem, dipped in clonex gel and into rooters. Times 5 and they all looked fine and the tip of the cuts was still closed like a flower but thats not uncommon for a few hours or so after they arrive in the mail.
Anyway I had to go to work and when I got home they still had not opened up in the clone dome with 90 plus percent humidity at around 77 F. I just figured they were still acclimating and by morning they would be open and looking normal.
Well by morning they had NOT opened up and looked a bit odd so I pulled out the tray and kind of carefully opened them up and they were not happy, looked like they had some dark material in the growth tips and withered. Id call it mold for lack of a better term or having dealt with it before. So back in the dome and Im trying to keep the humidity around 80% but its hard and its gone down to 60 before I caught it and closed dome back up and little spritz of water on cubes. I will add a pic in a few minutes but I have never had this experience before and Im pretty sure a couple at least are not going to make it and MAYBE on or two may bounce back, thats OK so long as I have one viable to grow out for another mom at this point.
Im scratching my head and I just hope this isnt a powdery mold situation but I kind of doubt the person who mailed them would knowingly send cuts from a plant with PM.

Pics and it’s not pretty. Two on end really look like they probably won’t make it. Tallest one looks most likely to recover and other two is a toss up. They look fine on arrival other than still like a rose bud that’s ready to open. No visible moldy looking yuk just not open. In less than 24 hours the brown stuff showed up and easily seen on leaves before I manually opened them up with a pencil shaped piece of plastic.
These pics about 36 hours or so after I manually opened the tips up.

This is not a case of powdery mildew.

Those clones are dead and rotting away.

I can deal with them not making it but don’t want to give PM any chance to enter my grow space.

They're gone. Just throw them away, and probably the tray too just to be sure.

Have you checked for insects? Mites?

No signs of bugs but I will watch them closely for any further issues until they expire or recover.

I'm seeing some signs of insect damage to the leaves.

Also they don't need 80% humidity, especially beyond the first day. 60% is just fine, so is 50%. I was clued into that when I saw a video from KOG in Australia, over a decade ago. He was taking clones out in the admittedly humid open air, no dome. What they need is just enough humidity not to dry out. Same with seedlings. That's why seedlings get damping off fungus.

 

[daleharris]

No bugs. I pulled 2 of them. The tallest one is still hanging tough and the other two look a bit better but I’m not going to trim off any more at this point for a few days which will either make or break it. I’m trying to keep humidity around 60% already and it’s kind of hard to control it that closely. At the moment.

Looks like they got cold or the temperature swung and the roots are tender on cuttings so snipping them off would hurt. If they had roots you don't need cloning gel,try a heat mat next time. The dark is necrosis. jmo

I have a heat mat under the dome for sure and fingers crossed here. I’ve got a feeling at least one will pull through.

You have thrips.

On the left photo, there is a picture of a thrip at it's larval stage. Notice the 2 feelers.

The second photo shows a lot of insect damage/predation.

Mystery solved. Man you have a good eye for insects Tanzan and you are right. The next question is did the clones come with those bugs' eggs?

I honestly see what you point out on the pics and can’t see them real time on plants with my USB microscope BUT I need to look again tomorrow.

Sorry friend your clones crashed. As the clones die the bugs do too unless they move. That's the main reason I don't ever use clones from some other outside source. NEVER! If you have other gardens in your house then you just exposed them to the same pests on the clones.

It can take a few weeks to a month for an infestation to appear to the naked eye. You wouldn't even know where they came from had you just tossed those in the trash. Another thing I never let anyone in my garden around my plants either because I don't want any f__king bugs. Look at all the time and money wasted using those clones. Sprout your own seed and pick the best keepers and clone off them.

I honestly see what you point out on the pics and can’t see them real time on plants with my USB microscope BUT I need to look again tomorrow.

Basically it's like this:

- The clones are gone. They're not going to recover. If they do, they'll forever be infected.
- They can infect other plants in your grow.
- For your own mental health, you need to chuck the diseased plants, and move on to growing healthy clones. And don't give it a second thought - keep moving forward.

Seeds have their own problems, however they don't transmit insects. So that's something to look at.

 

[daleharris]

I keep looking and can’t see any. The second pic you pointed out under microscope that appears to be some kind of plant matter to me. I’m checking them every 8 hours or so like a hawk. If that’s what they are I will definitely keep looking for them.

 

[Hammerhead]

IMO not possible to say that's from Thrips. The amount of damage is minuscule. Necrosis isn't good, pick the best looking snips and try to save them. Most likely a temp issue that caused the Necrosis. The tray will be fine after it's cleaned with bleach.

 

[daleharris]

At this point I’m not seeing it but IF I get at least one to throw roots and be viable anything including thrips will be in for a war. I keep all my plant bags from main grow of 5 gallon bags to 5” square plastic pots with bonsai moms and backups crawling with hyposaspis miles predator mites that are always there looking for fungus gnat larvae and they also like aphids, thrips and other pests but unfortunately not the borg. I transplant them by the table spoon from big bags to small pots when I pot new moms etc. about once a year I buy a new batch. I can always see them when I pull a sample and look under one of my small inexpensive USB microscopes. If I feel like I need more Natures Goodguys has plenty of more specialized predators as needed but if their food of choice isn’t available they die off. IF one or more of these make it to pots I will grab something from here to slay them.

Thrip Control

Thrip Control A common pest found in greenhouses and indoor/ outdoor gardens, Thrips damage plants by sucking their juices and scraping at fruits, flowers and leaves. Plant leaves may turn pale, splotchy, and silvery, then die. Injured plants are twisted, discolored and scarred. Think...

Basically the way I see it is this:

- That's a thrip larva

They grow and as they grow, the size of their bite and damage increases. This is a very early larva that just came out of an egg. That implies there are lots of eggs around.

Basically if you see insect damage - there are insects around. If you see 1 insect, there are dozens or hundreds of insects around. Or in this case, hundreds or thousands of eggs waiting to hatch.

- Thrips spread tospoviruses

I'm not an expert on viruses, however this looks a lot like the rest of the damage/necrosis.

- It's a clone, indoors

If this was an adult plant, outdoors, I'd say some thrips wouldn't be a problem. You just use water pressure and some fermented sprouted hempseeds/microgreens full of plant specific beneficial bacteria, fungi and sugars, and that's it. However indoors where there are no predators, prevention is the thing.

Just for information I came across a post about these crazee mites that are seemingly the top predator mite there is but it’s not available in the US it seems at the moment.
