New plants from other grower- some damage- correct diagnosis much appreciated

[Immune]

Some info:
-are 3.5 weeks old
-transplanted two days ago. I had to untangle the slightly rootbound roots so I dunno if it could be shock.

some symptoms that I see (check out the pics)
-blistered chlorophyll
-white spots that look like nute burn/bleaching. (possibly getting worse)
-slight leaf curl
-light green tops.
-some contorted leaves

My best guess is that the grower I got these from had the mosaic virus or broad mites, but I have only brief knowledge when it comes to plant illnesses. So if you know what you're talking about pleeeease post!

every grower should have a microscope or good magnifying glass to inspect for bugs. bugs can mess everything up. once u figuire out what it is you can use the mmicroscope again to check on egg development aiding in reapplication cycles.

best of luck

I would do a dunk in something like Physan or Oxidate in any event. Quarantine is always a good idea.

I do see what I would Dx as a Ca-, too. I agree about having a scope of some sort, around 10x or so is very useful to start. I prefer an actual jeweler's loupe, far better viewing.

Good eye, Some of the spots sort of look like a calcium deficiency. How should I treat that?

And jewelers loop sounds like an awesome idea, growing pot with class.

flip a leaf with the white spots over an take a pic to show. i bet ya find eggs.....MITES aka "THE BORG" ya brought home a grow room killer my friend. good luck

I'm not sure those are "mite bites"... Just because the spots seem to be in more of a pattern. Just my opinion...

But if they were my plants I would surely be checking, OP. You don't need a scope/magnifying glass to check for mites/eggs if you have decent eyes but it does indeed help.

Good luck my friend!

Yep. All I can see in the pics is a fairly progressive calcium def...

As requested here are some pics of under the leaf. The spots mirror the spots on the top of the leaves and they don't really look like eggs to me.

I have a question for you...

Why untangle the roots? If the plant was rootbound, all that is needed is a transplant to a larger pot. Untangling when un-needed is a sure way to see stress...

 

[Arthritis_sucks]

ttheres somethin crawling around down there....maybe white flies? couldnt see close up. macro shot maybe?

 

[Neo 420]

Oh yea..... You got insects......

My buddy said that if the plants are rootbound they cant stay in the ball. I'm using growbags, what's the general consensus on this on the forum?

... Did you transplant to a bigger pot? When plants are rootbound, you simply put them into a bigger pot/bag whatever....The plant will take cares of the rest..... No need for a consensus, unless you got something else going on..

Neo, I've found much quicker response if I pull the roots apart. But, the way I do it would be considered akin to rape by some.

Can't say what others do, but I pull the roots apart. I don't bother untangling them, I just grab & pull. If they need to be cut away, that's what I do. I have found that if I simply transplant, it's common for the roots to continue circling instead of finding the new media. If I pull them apart, and lay them onto the media in a spread out position, response is fairly immediate.

 

[Neo 420]

I have never seen that issue with any transplants I have completed nor with any other gardeners I know. I transplanted a severely rootbound plant just 2 days ago and it never skipped a beat.
What's peculiar is you say it is common for you to have issues transplanting a rootbound plant without breaking apart the roots. I have had quite the opposite reaction.

I am sure you consider yourself a advanced grower with some of the knowledge you have but I think it would be wiser to teach new or beginner gardeners a more standard approach to application. I know and understand various root pruning techniques such as wrenching, box cutting, undercutting..etc but these are done for specific instances such as slowing down a plants growth, higher shoot to root ratio or short denser root systems.

Plus the OP gonna need them roots to help the plant bounce back from the insect/unknown damage.

 

[SeaMaiden]

Neo, that's not what I said. Please read what I said again.

As for what I consider myself, that's another story, but please allow me to point out I've been cultivating and growing many types of living things for quite a while. My experience is hardly limited to cannabis, and in my experience it's just as good to treat cannabis as any other plant, and the literature bears out my experience, which is to give them a head start by opening up the root ball. I do worse than that, and they don't experience problems. I don't see why a person's newness at growing cannabis has anything to do with it the advice I've given.

Every plant I transplant, whether it's a cutting or seed I've started myself, or something I've brought home from the nursery--if it's rootbound those roots are pulled apart. Try transplanting one plant your way and one plant my way, give each 2-3 days, then pull them and see what the roots are doing. IME, those of the plants whose roots have been opened up are already finding their way into the new media--this is my goal--whereas the plants that have simply been dropped into new media show roots that continue to circle for a bit.

In my experience this is even more important to know if transplanting directly into the ground, and even more so if you're transplanting into poor soils.


The damage is clearly Ca-. It is not unknown, it is not from insects.

 

[Neo 420]

No argument on the Ca def but I stated unknown/insect damage because of this pic which is not totally clear...


As far as pulling roots from rootbound plants, yes it can provide benefits but its something I wouldn't of recommended it. (call me ignorant if you wish)
It looks like the OP is using smart pots (i maybe wrong) which shouldn't be rootbound anyways......
