leads me back to the nutrient ratio or water source

something is out of balance or something "caustic" is around

Could try to increase you're floragrow ppm slightly, see what moe and aqua say

Pathogen?

freakin shenanigans i tell ya!!!

thats why i started to foliar spray the smaller worse looking one to see if anything changes over the next couple days.

i haven't put up the Aqua signal yet... was hoping it would be something dumb that i was doing and wouldn't need to bug him.

Pathogen?

bird flu... idk...

 

[Observer]

If you're foliar spraying the ones that look bad, and they get better they might need to increase the ppm?

Which doesn't make sense though because smoke is flowering big plants in 400ppm but that's because they are sitting comfortable with their health(?) and the available nutrients are right there when needed though.....

Leading me to think again ratio or something caustic

if not to raise but to change, that foliar spray is great for deficiencies and lock outs. i call it my foop oops fixer!! and if it gets worse then i didn't waste a lot or hurt both plants trying.

and on top of it he's on a 700 scale!!

it's def not out of the equation. and if it's either one a dumping and cleaning is in order. it wouldn't be that hard to do.

thats important, maybe, 120ppm difference. and the way its measured

What's new Stoney? Any changes?

What's new Stoney? Any changes?

still the coarse, slowly growing, still curling, and still burning. both ph and ec have slightly dropped over the past week.





do you think it's time for drain/clean/remix new solution?

 

[moe.red]

Any potential for contamination in the water? Any chemicals or herbicide or anything you can think of? PVC solvent? Chiller disintegrating? Did you do any work on the system?

Coco is pretty wet netpots are not touching water?

I’ve seen nute imbalances cause a lot of weird shit but not like this. This feels like a contamination or pathogen. But I’ve been wrong a lot just ask my wife. Easier to count the times I’m right.

Can you feel heat if you place your hand between the heater and plants?

there's a possibility on the chems.. from when i bombed/bleached/sprayed for like a month straight. i didn't flush or sterilize after that. i covered the buckets and bombed... it's possible some got in, the lids weren't perfectly sealed. i had hoped since the air stones were going nothing could get in.

i want to carefully dig back on the coco more and make sure i'm not dampening them off or choking them out somehow. i didn't pack it in there but they seem to be almost showing those symptoms.

about the only other thing i can think of

this is where it at by this point i think.. so many other bases have been covered.

like i said i just want to carefully scoop back some coco and get a good look at the stem down to the root base.

and if nothing looks odd i think it's time for the solution swap.

no, when it's on you can put your hand right in the fins and hold it there, i'm guessing 90° right on the metal.

The air pump would have actually drawn the air into the water if the pump was in the same room as the bombs.

Root issues could definitely the issue. See if these guys suggest H2O2 or the like [Hydroguard].
I think the coco could hold more moisture than the clay balls do.

the pump was in the lung room but that still doesn't guarantee some bomb cloud didn't get in or was completely purged out.

i'll dig a bunch out and take some pics of the tap root. i'll give it all a good whiff too.. sometimes root problems can be smelled.

""This seedling was being grown in pure perlite, which is not a suitable growing medium for cannabis, and as a result the roots were not getting the proper levels of air and water. This seedling needs to be transplanted to soil or coco (or even into hydro) in order to get better"

this is just straight false though, ive grown plenty in pure perlite with no issues.

i dug out the best i could till i saw roots and didn't want to break any.. i don't see or smell anything foul..





i noticed the top of my elbow had gunk on it that wasn't there before. not sure if that means anything,, i felt the bottom and the rez and it was squeaky clean, no slime.

 

[Stoneyluv]

like the poor plant below (this was caused by poor drainage and plant was overwatered, leading to a pretty severe case of root problems):

that looks kinda like mine^^

could mine be lack of O2 or excess of co2 in my rootzone?
i'm going to turn my bubbles up...

 

[Stoneyluv]

i also just learned that my water temp probe is off a few degrees. i used a trusted probe and it was 74.6°. i lowered it three degrees along with turning up the air bubbles.

Don't think it would hurt, and can't rule that out yet either

If this cycle continues after that, rezSet (?), after reading about all the bug bombing you did lol

That does not look like root rot to me.

The junk on the elbow looks like bits of coco fell thru the pot. Can you identify?

That is plenty of bubbling. But I agree lack of dissolved o2 will cause lots of symptoms just like overwatering soil. I’m just not seeing how with that much bubbling and pumping going on.

Is it just me or is that water dark as root beer?

What we have here is systemic failure. Many different symptoms. Something that is poisonous to the plant could do this. Lack of an essential element like o2 or co2 or inability to move water up the stalk could cause this. Roundup kills by stopping protein production for example.

If you do not have root rot
If you have good water chemistry and good do
If the environment is correct
What’s left is some kind of contamination or pathogen stopping one or more plant process needed to be healthy.

If there is contamination and it is still happening swapping out the res is not a long term solution. If the contamination is not happening any more it might help.

Lets get @Aqua Man and @smoke in on this.

Ok read a bit and pics give me a few initial thoughts, the leaves curling that tight and far up the petiole kinda say russet mites but its lacking the total canoeing of the rest of the leaf.

Root infection or damage can cause a very similar ration in leaves. However they physically look fine and have 0 concerns of root rot.

Heat/light/wind combination stress will absolutely show these signs.

What is the actual leaf temp?

What is your fan placement and is it blowing directly on plants?

What is the ppfd of that blurple that is 18” away? Also how many watts and what power setting is it at?

100% Environmental conditions sound good if accurate. Using leaf temp for VPD?

Has anything been sprayed on the plant? In the room? Or anywhere that can be introduced through the intake? Eg cleaner like windex, pledge etc

 

[Aqua Man]

Its definitely not environmental like co2 (will cause drooping and transpiration issues) as will VPD. Those are good.

Unlikely its nutrient related (if it was magnesium only the serrated tips would spike but thats not the only thing that causes that)

Definitely not root rot but possibly the roots may be getting beat up by sprayers or to much flow/agitation although very unlikely without seeing physical damage and infection set in

 

[steamroller]

In short we are considering the water source possibly being contaminated when the room was bombed.
Stoney how does the same genetic in soil look now for compare?

Possibility… how ling ago? If longer than a week unlikely as the damage would show decay and definitely a noticeable shedding of roots or damage.

If very recently then definitely possible but will also show decay soon if its the case.

That blurple is my number 1 concern as of now with or without possible combined wind stress

 

[steamroller]

Bombed before the grow was started.
In my head I kept remembering that blurples are much more 'powerful' than full spectrum lights.
I think we even have a thread about PAR differences of the two, but Stoney has used these lights for long time.

100% where my concern is right now brother. And direct wind will exacerbate the heat stress it causes at the leaf

 

[Aqua Man]

Ok tried to find the light and i think its a california lights works 550.

If so these babies are being cooked. Manufactures recommendations are always too high and here is a chart they give.
