chemical burn?
 

so i think my nanner may have gotten chemical burns from some mg fert, opinions?

Re: chemical burn?
 

What was the fertilizer and what was the dosage?

Re: chemical burn?
 

cant find the exact fert, and i think i left it at the old place when i moved, but something similar to this: Miracle-Gro® LiquaFeed® Tomato, Fruit, and Vegetables Plant Food - Scotts Miracle-Gro
it came with a measuring spoon that you screw on to the bottle and the mxing instructions were 2 spoonfuls per gallon so for 4 gallons, i did 8 spoonfuls.
i went down to a local hydroponics shop and told them about it, and they said it was most likely chemical burn due to using a fert meant for soil for buffering qualities in a hydro set up. they had me get a quart of botanicare aquashield and gave me some general hydroponics florabloom with mixing instructions of 2 tsp fert and 1 tbs aquashield per gallon (although the bottle of aquashield says 1-3 tsp per gallon, i think the email she sent me may have been a typo. i am currently using 2 tsp per gallon) until it comes back, then go to the proper mixing. i am only using 3 gallons of water at the moment.

With nearly all plants in the hydroponic environment, the fertilizer must be urea-free.

Re: chemical burn?
 

This means that urea burns bananas in a hydrophonic environment, what about in soil?

When urea is applied very close to the p-stem?

Is burning? Is this an urea issue? Does this problem also exist with other nitrogen-sources?

Re: chemical burn?
 

so are we thinking urea burns? if so how long for it to heal? or is it doomed?

Re: chemical burn?
 

When you use regular fertilizers in a hydroponic set-up it is alos easy to over-fertilize and this can cause nutrient lock-out where the plant will no longer absorb nutrients. I did that once and most of the plants died (Colocasias) but a few survived. I removed all the substrate from the roots and soaked them in regular water and planted them without any fertilizer and eventually they grew the tiniest bit and amazingly over-wintered in the ground as tiny plants (basically zero growth all season from starts) and they grew fine the next year.

Re: chemical burn?
 

how long did you soak them for? and did you plant them back in hydro or in soil?

Re: chemical burn?
 

You must be joking, right? Surely you didnt plant your banana in pure non- organic fertiliser?? Maybe that medium showing is a new American product that Ive never seen, please tell me!!

Re: chemical burn?
 

I have seen urea used as a grass/weed killer.

Re: chemical burn?
 

it was roughly 1-2 tablespoons per gallon, the medium is hydroton, or expanded clay. its meant for hydroponic growing.

Re: chemical burn?
 

Steve, I think you should try again but make sure that for hydroponics you use a fertilizer that is labeled "Urea Free". If in doubt, look at the "analysis" section on the label where the Nitrogen components are listed. If one of them is Urea, then don't use it for hydroponics.

On the other hand, urea (which is made by extraction from the atmosphere) is an excellent nitrogen component for many types of plants growing in soil.

Re: chemical burn?
 

will do, how long do you think it would take for it to come back?

Re: chemical burn?
 

i was able to look at the mg breakdown, it was a 9-4-9 with 9% urea under nitrogen

Re: chemical burn?
 

Outdoors in soil about 6 weeks. In hydroponics -- depends upon several details of your setup.

Re: chemical burn?
 

OK sorry, I`m not into hydroponics, but I thought they were only good for vegetables or tomatoes etc? I dont see how a banana plant can grow under such conditions for any length of time, they are such " free spirits" of the plant world!

Re: chemical burn?
 

I know of several successful hydroponic growers of bananas. Most of them are outdoors or in arboretums where the cost of lighting is insignificant (or zero).

Re: chemical burn?
 

first guess

what is PH Alex?

what is yours?
I'd bet with (did you say 8tsp in 4 gal?)
WOW !
and by WOW I mean RIKES!!!

I'll bet your PH was 4 and the PPM was 2000 (or less and more)
why not mix that solution again and post back the PH results... unless you don't have a test kit.. ooooooohhhhh
go on ebay and get the GH PH drops kit don't mess with the electronic ones

You should VERY seriously consider a new media because the first time that nanner tips over you'll spend the next 3 years cursing hydroton every time you step on one of those hard *&^#@! marble like rolling around *^W&E#( little balls
Imagine tipping over a 5gal of marbles LOL

Don't get ripped off at a hydro store, those places are for potheads who are too stoned to do math (low analysis anyone?)
Get with Richard about some soluble nutes.

Re: chemical burn?
 

not sure what my ph was with the mg, but now its right around 6 with the correct mixture and hydroponic nutes. the store i go to is a full on garden store, but deal primarily with hydro stuff, theyre not stoners, some of their clients may be, but i trust them.
