So i have an aquaponics system and i had a bad potassium deficiency wich i miss took for iron. So now im lost i thought it was iron and added chelated iron spray....nothing changed then i added bannana peels to the grow bed my leaves are still yellow and wont grow and have been this way for a couple weeks not sure what to do.

Everything is checking out my ph is a lil high but not high enough for neutlock out its about 6.8-7. My alkalinity is good nitrates and nitrites are fine. Water temp and air temp is good im at a complete loss. Ive suplemented potassium and iron. And not sure what else cpuld be wrong

How close are your lights? LED's need to placed farther away than most people think. Also, doesn't your PH need to be more like hydro and not soil? That would be 5.7 - 6.2.

Is this some kind of troll account...?

No its not a troll account its a new account. And no fish need a higher ph to survive 7-7.5 plants need 6.5 so its hell finding a medium for both as the medium tends to be torwards the limits of either. And leds are about a foot away not up on it my cfls are closer. My nutes are obviously not being taken up and i need help figuring out why. If u cant help please dont waste my time

LED's need to be around 18 inches at closest if what I've read is correct. I don't use them that's just what I've gathered on this site. As for your PH. Your plants are not going to do good at that PH.
Aquaponics is a neat way to grow if you can do it. I think some plants grow better than others using that method. I don't think cannabis is one of them. Those plants can still be saved but you're going to have to start feeding them some nutrients which you can't do in your aquaponics system.
It all comes down to what you want. Do you want to end up harvesting bud or do you want to spend a bunch of time with a biology experiment? Because I don't see you harvesting any bud with your current setup. Sorry to say it but it is what it is.
Good luck regardless of the path you decide to take.

Thank u for ur help. Thats an answer i was looking for. See my ph like u said is a huge issue because the balancing act that it requirs for both plant and fish is crazy. 7.0 seems to be the medium and thats looking out my nutes ima drop my ph down to 6.5 and see how my fish do if badly i guess ill transform into hydro ponics. Another question xtsho do u think a sump tank would help. I know my system is small but perhaps i could add one to kindof bridge the differance like adding in potassium magnesium and iron which are the main three nutrients that lack in aquaponics. I just really want it to work as once one is up and running. Its a self sustaining system which would be my ultimate goal. Basicly other than changing to hydro do u see any other options i could fix to make this system work

It has been pointed out before that it is most cruel to do aquaponics unless your really good at both growing plants and keeping fish, both of which your not impressing with.

The grow was over the second those plants burnt up, the welfare of the fish one can only hope....

I'm not very knowledgeable with aqauponics. I looked into it years ago but then got tired dealing with my 55 gallon tank and gave my fish and everything away. The thing is, those plants are unlikely to make it without changing grow methods. They don't have enough time left for you to get aquaponics dialed in. I do know that it can take awhile to get your system ready for plants. Cannabis needs lots of nutrients so you'll need lots of fish making lots of poop. I don't know the size of your tank, amount of fish, or how long you've been preparing the system. Those are important variables. Some plants like lettuce and herbs require much lower amounts of nutrients and do well. I would take a step back with cannabis and aquaponics and grow with a more traditional method that will give you guaranteed results. In the meantime you could experiment growing lettuce or herbs using aquaponics. From there move up to tomatoes and peppers. If you can get your system to support tomatoes and peppers successfully then it will be ready to try again with cannabis. One step at a time.
Sorry I'm not more help.

Well arent u a special kind of rude. For one this is my first time at aquaponics wich is diffecult to stabilize but once stabilized i put my first 6 harvest on the fact that it will do better than ur hydro. Again if ur not here to offer helpful advice why dont u try keeping ur damn mouth shut. Im bout positive u wouldnt talk like that in person so why dont u show some damn manners. And most cruel my ass. Once balanced it is completly healthy and kinda how nature intened. I dont pretend to know everything as that is why im asking for advice to help solve the issue. Unfortunatly only two people have offered helpful advice. As for the last coment. I have two 55 gal drums filled and holdin a total of 20 goldfish. Some shubunkins some comets but there goldfish wich i chose because of there resiliency to infection and tollerance of water quality. My only guess is that nobody on this site has experiance in aquaponics much less aqua-aeroponics. So i think im on the wrong site to be finding this info. My fish are stocked according to the info by the pet store. I havent lost a single fish so im not hurting or killing them they swim around and are loving life and minus there dislike for pellet food everything is fine with the fish. Just never mind im deleting this accou t

There is an aquaponics section in one of the forums i think, you cant delete accounts though, waaaay not allowed, something about democracy and crap site rules idk. Before you run your plants through your fish tanks maybe try to hit certain set points for nutrients and water quality as well as a tried and tested plant system, you want to hit the ground at least with a stride, better if you start running.

There are some great additives for aquaponics, a google of some threads will yield you a ton of knowledge and especially ideas and fixes to your problems than we every will, at least in the short term.

Im sorry you dont like the advice about the fish and plant health, its quite well known amongst some here and been brought up that the animal welfare is numero umero priorite. As you havent shown this but only some very sick plants and a blurple light i have not really said anything apart from the recommended spiel.


Of the top of my head aquaponics systems are not as productive due to a heavier management of the nutrients and vastly more complex system/s. It is reasonably unheard of for cash croppers and big yields, more something sustainable with a view to world food shortages and modern technology unlocking redundant farming methods. Certainly the Chinese like to culture fish for market in their rice paddies and other cultures have made their uses of aquaponic techniques, not so reliant on the fish as growing plants in man made tanks as you are trying to.

Your problems overall seem to be that the environment and nutrients are waaay of, those plants have had issues since germination, it would be far too technical a stab in the dark to bring that down to any one or few single issues.

Good Luck :mrgreen:

Ideal pH for aquaponics is 6.4 to 6.8

If tap water is used, you'll have enough calcium, otherwise you'll need to add that too. I do have Gypsum on the side for backup.

I get most of my phosphorus from my fis feed, but also keep Rock Phosphate on hand.

I use Epsom Salt for Magnesium, Potash for Potassium, and FeEDDHA or FeDTPA for Iron.

I feed with Aquaorganic brand fish feed.

I recommend duel root zones to help with buffering out deficiencies. I use a combination of soil and aeroponics in my system, ...and newly fogponics with soil, but in the past I used hydroponics with aquaponics.

If you have any questions, I'm here to help..

I've been growing cannabis in aquaponics on a large scale for a few years now, and currently get 1.5gpw consistently.
