Gonna have to say you are being pretty non specific when we ask you specific questions. Not the best way to get help....also straight up not answering many to. Good luck.
Peace, negative.
I did look at the AG site, and the stock feed looks reasonably balanced. The dosing info was at least partly nonsense though. Revolving around pod count, instead of water volume. With a 50% ramping up of feed in all but one size, where there was non. Which can't be right.

In the reviews, I quickly found people stating the EC they used to make these work, but it was in PPM, so can't be relied upon.


Going into hydro with guidelines like start with 8ml, then add 12ml every two weeks, is a failure waiting to happen. That's the 9 pod, we might be looking at. I'm not sure, as it seems they are all different units now. So how big a 9 pod does the bottle mean? It's not workable for a guy with my brain.

Is the air stone causing enough water circulation in the res? Sometimes roots can block the water movement if there isn’t enough room in the tank



And like @negative37dBA wrote, it’s better if you answer clearly the things people are asking you, so that they can help you asap ..nobody is interested to use their time endlessly helping someone who isn’t even bothered to provide information people are asking ..just saying, mate

Number one thing is the plant needs more nutrients.
You may be right. Like 40% more. I dismissed the idea until other things were looked at first. Looking at the feed though, perhaps he is counting plants, not system size. The data is a little thin, as others have said

They look like the pH is too low and they are starving. i would double what you have been feeding them. Sure can't hurt at this point. Try to keep ph at 5.8.
It's hard to troubleshoot when OP hardly has given us any information about how he operates the system like nutrient strength and reservoir change frequency?

When I asked about preventative measures and sterility he didn't even answer the question? It's hard to help someone who doesn't seem to want to do any work by themselves and disregards questions relevant for troubleshooting?

I agree that pH is on the lower side. It's better to run slightly higher pH in veg to make Ca and Mg more accessible to the plant and later lower in flower.

I love your determination and persistence. Cheese you've been around for a long time and grown a lot of plants. I see you are still avoiding buying an EC and pH meters. I don't know anyone growing cannabis hydroponically that doesn't own or use an EC and pH meters. You are the only person. If you knew what you pH was, you would know if your plant is getting too toxic or starving. You will continue to have problems and try to guess your way out of it until you get some meters and learn how to use them. Good luck.

He can't give you any info because he doesn't use meters.

Then we're back to its hard to help someone out who doesn't want to do any own homework or post any relevant data for troubleshooting?

We can all make guesses and assumptions based on a very thin data sheet but I'm afraid that doesn't help OP out?

Yes.
In soil growing, if you have good and stable water source and you more or less know the pH level, those meters are not needed but when you grow in hydro you just have to get them

I'm not sure this type of Aerogarden are big enough to grow cannabis plants like the one pictured here, it's made for ornemental plants and small seasoning plants but I don't think it's adapted to grow cannabis, that's the main problem here the growing material is not made for being used this way so of corse you run into trouble while using it. In this conditions I would transplant in soil to keep the plant alive, I don't thing there is better option.

If that's the case cheesebuds, I'd highly recommend spending the money on this stuff.
Kinda the first thing to buy before going hydro.

Nowadays there are combo pens for small money.
Dont think about it, just do it. Your plants will love you for it!
If you need help calibrating or measuring,I'm happy to help you out.
Just in case you get one..don't forget the necessary calibration liquids needed!

I'll add this link. I have the smaller unit and it works a treat. Measures faster but still as accurate as the bluelab pH pen.
probe tips can be changed too..win win.

That's in Australian dollars!
Not sure where u are,but i think this brand you can get worldwide.
I'd stay away from the 30 bucks tools. They're usually shit

OP: lemme guess, led lighting?

That plant isnt drinking at phototime, but white roots indicate that the roots are fine. To me that would indicate a problem with transpiration. What is your airtemp/rh? Did you ever see the plant really stretching out the leaves instead of this saggy posture? You can compensate for low drinking by adding some more nutes but only up to a point or the calmag will start locking out K. You need to get the plant transpiring which you see by plant posture; stiff leaves stretching out horizontally instead of sagging.

Led lights dont carry any infrared heat which means you have to tweak the environment to get it drinking properly, basicly a little more heat usually does the trick. Some people solve this by adding a low watt incandescant bulb.

Led lights dont carry any infrared heat
Not starting an argument but that just isn’t true..

Absolutist statements are many times wrong,in this case too

Led diodes do emit heat that we can easy feel on our hand when we put it under the lights. even light out of my led bicycle light feels warn on my hand. They don’t emit it as much as hps lights do but leds do emit heat
Peace

This is true, you can feel some heat from visible/PAR light aswell. This is cause some of the light gets absorbed by your hand, not all light is reflected back. Ive even seen high intensity LED COBs melt wiring, plastic reflectors and even being able to light a cigarette. All electromagnetic radiation can cause heat, not only infrared.

However, there is pretty much zero infrared/+800nm in white LED emissions. Just cause you can feel heat on your hand doesnt mean that its infrared emission. Point is that plants have developed their metabolism and transpiration adapted to a light source which is part visible light part infra red. If your plant is only getting the visible light its leaves will generally not heat up enough to cause similar transpiration as it would in sun ligh or under HID.

No argument here, led light can heat your hand of course, only that the feeling of heat doesnt come from infrared.

Infrared is radiated heat: the feeling of warmth from the sun on your face; the heat from a coal fire, or a toaster. It is even the same form of heat emitted by your own body. It is the most basic form of heating known to man.

What is Infrared Heat? Why does it feel so good?


People who have IR diodes included in their lights have the same led problems as people who’s light don’t have IR diodes. This was figured out already 5 years a go

If you have temps at around 28 C or 83 F and humidity around 60% and your lights aren’t too close to the plant and you don’t have colder air blowing strongly straight at the canopy, then OP’s issues should be something else



His plant was growing under the aerogarden light just fine 3 weeks a go, so i doubt the light is the biggest issue here

Because no growled i ever came across actually have IR diodes, as in +800nm diodes, its just marketing. Some brands call their 730nm Far reds infrared for some reason but they are technically not infra red. And as you say they wont really change the situation, i fully agree here.

As for your definition, well its not exactly right im afraid, try wiki instead of a company marketing blurb. Infra red light is light (electromagnetic radiation) from 780 nm to 1 mm wavelength and is generally very good at heating as it gets absorbed very easily. Any electromagnetic radiation, including visible light, absorbed by an object will cause it to heat up, not only infrared. Visible light is a bit special in that it tends to get reflected (thats why we can see it) rather than absorbed but in no way am i saying its 100% reflected. Its not a matter of if led lights being able to heat the leaf, ive already conceded that happily. Its if it heats it enough, in comparison to the light that a plant evolved under.



I fully agree on the rest, as in pushing temps to around 28C with ledlights (instead of around 25C for a light with real infrared). This is also what i said in my initial post; add heat until leaves are stretching out. If its not feasible to add heat to the growspace then you can add it directly to the leaf with an incandescant. Not sure what youre after here but it does seem like you wanna argue about nothing.

As for the pics in the link: they kinda confirm what im saying, sloppy plant posture means low transpiration, as we both agree OP should add some heat to the grow :)

Edit: sorry, this post sounds a bit bitchy, no harm meant and in the end we agree on what is going on: plant looks hungry. The only point i wanna make is that with this type of very typical led nute deficiencies its better to sort out transpiration first and check how the plant grows before starting to play with more nutes. All the best
