Yo! I have two plants out of like 20 that look like this. I’ve since quarantined them outside.

I pulled one of them out, shook off all the soil and looked very carefully for larva of any kind. Nothing.

Looked at many leaves under a 40x and 100x microscope, old and young leaves, no mites that I can find.

Plenty of information about how I grow that I could list, but does anything jump out at anyone before I do?

I’m not attached to the outcome of the plants. I’d just be happy to figure out the cause.

 

[LoveGrowingIt]

It doesn't resemble any deficiency I know. I thought about zinc deficiency, but probably it isn't. I also considered over watering, but no, that's not likely. Then I decided it might be an infection because the pattern is irregular. That's my best guess.

 

[budsofgeorgia]

overwatering with some light stress/burn

 

[Rama777]

100% not overwatering. Light stress/burn perhaps is involved, but only as a result of a greater health issue that would lead to that vulnerability.

I have been thinking infection. Any idea what kind by chance?

 

[Captspaulding]

That is def a fungus/virus issue,
As well as a bit of professor x kinda plant.
Interesting growth.
Also, I’m fairly certain that dirt, is very hot in something,

 

[Rama777]

Well damn. I don’t plan on using this new dirt that I tried on the last bunch of plants..

Virus, fungus, insidious..

I took the two plants out. I see one plant that has the tiniest bit of these pitying symptoms on a single small leaf. Think I should pull the leaf and monitor the plants?

Toss every plant, spray the tent down with nasty chemicals and start all over?

Not really sure about the severity and sucks not knowing what species I’m working with..

I run hepa filters on all my intakes damn it!

It’s not fungus or light burn. Looks to me to be a bit over fertilized. Water with plain water for a week or more and the new growth should be healthy. Foliar feeding with some calcium and micros will help too.

I haven’t fed any of these plants but as captain said, the soil does seem hot in something..

I already scrapped the plants. I don’t need them enough to justify the risk.

I also agree that a fungal pathogen is not likely. I’d point to viral or bacterial as potential culprits, all of which are contagious and freak me out extra indoors..

 

[BB22]

The leaves with the yellow edge look like the pic some potassium deficiency.

I’ve heard/read LED lights can cause this. But I’ve only being growing for a year and a half.

Hey so I could be wrong here too homie,
But as far as the mag issue, I don’t think this is light driven, I think this is a nutrient surplus in medium causing uptake issues.
Mag generally does not cause leaf distortion, just discoloration, also the pitting on the leaves. That’s not run of the mill nutrient tox, or deficiency I’ve ever seen. And if it’s only one plant out of a group of the same strains and it’s the only plant throwing these issues, it’s a bit more than a bitchy pheno I fear.

Well one thing is for certain. For my produce starts, I never run with super soil type mixes. I do 50/50 blends like almost always. I’m going to apply that to pot plants going forward. That way if shit gets out of balance, I can more easily blame myself instead of wondering about the soil..

Eliminate as many variables as possible.
Infiltrate destroy and rebuild better.

Bog, the most clairvoyant cartoon stoner pup of the farm, that 8 ball is waaaay better in his hands, than up this schnoz.

Chop me out bog man!

 

[HappyHarvestHaze]

It could be a light burn; you might need to adjust the distance or intensity.

 

[KeyFingerFlying]

I'd say Zink and Magnesium, but those dots can be a result of an infection, check the soil and roots, check water, it is something internal, not the light and not the temperature

 

[Rama777]

So, I am doubtful that this is a deficiency, rather a lockout and more than likely from an infection. But since I still have these plants isolated somewhere..

What are these new leaves deficient in, regardless of the cause?

 

[Thatoneguyyouknow_]

some of your pictures look just like the way some plants express potassium deficiency, others look like a mosaic virus.


Sorry for being late to the ballgame here lol.

Lol, well, I nursed those plants back to perfect health almost immediately with a flush. Must have been a bad batch of soil, coupled with sensitive genetics.

I have since changed my soil approach. For now I’m copying mikedin’s mix.
