Help! What am I doing wrong here?? Leaves browning/drying

[rugby]

I'm growing these in an Aerogarden Farm Plus... I used their fertilizer liquid... but this is what is happening to the leaves. Anyone have any suggestions on how to fix this??
Thank you!!

First thing I'd say is major nute burn. I haven't tried growing in an Aerogarden, but I'd suggest stopping the fertilizer and see if she recovers.

I would guess this grow medium is inappropriate for cannabis plants.

Aeroponics can be difficult. Much easier to mess up than hydro, and way much easier to mess up than soil.
What are your water temperatures like? Notice any slime on the roots?

[Qwertywill]

Whats your pH?

[Cali]

In my opinion your not growing natural. Trying to reinvent the wheel don’t work sometimes. I think nutrient burn and heat stress

[Scarletwhitewidow]

it probably nut burn and starting damage the roots.put in fresh pot or palin water let it heal roots and try a again setup up correctly.That obviouly messed up

[SoOrbudgal]

Never used that setup by the looks of it I never will. I'd toss that plant. Sorry for your loss

I've grown before in the aerogarden before and gotten great results. I think I overdid the nutes this time. I will toss the sad looking pups and start over. Ya live and ya learn!

That said, do most of you add nutes at the very beginning or wait a bit?

Thanks!

[Cali]

I wait until they are one week old atleast. Well I used to lol now I just worry about keeping my soil moist that’s all.

Whats your pH?

THe pH level if I am reading the device correctly is 7.96 . It's Paris tap water.

Fascinating... if I run it through the Brita filter it comes down to 6.26 . Is that possible???

[Toker1]

Ph is way too high. 6.5 is the maximum. Should fluctuate between 5.5-6.5 for best results.
How do you keep your water temps in control? Is the room it’s in AC controlled?
Yes, filtering water can have an effect on PH. As well as other factors.

[rugby]

@Toker thank you. By filtering it it's at 6.26 more or less... The room is not AC-controlled but it doesn't get very hot here... maybe in the 70s during the day and 50 at night.

[Toker1]

Yeah, you want to hit the range from 5.5 to 6.5. Consistent 6.2 will lead to deficiencies in elements that get absorbed at the lower ph levels.
70F with the pump spraying water around can lead to heat issues in the water itself. Water temp fluctuations will also cause other ph issues.
I use a small aquarium chiller in my aero clone machine. Really helps with those types of problems.

Toker1 what is the ideal pH then? I was at almost 8 before the Brita filter!

I was surprised... when I changed the water which is like 2 gallons (?) it was VERY warm... like 100F warm... what the heck?

[Toker1]

The pump heats up 2 gallons very quickly.
For PH...I try and hit 5.5. Then let it drift up to 6.5 before I adjust it back down again. Think about it like you want to hit a range of numbers, rather than a specific one.
