Question about Canna Coco A + B

[treedup]

Hi all.....I am hoping some users of of the Canna Coco line can help me figure out what I am doing wrong.

I have been using the Canna products for a few weeks now and I seem to be having an issue with my PPMs coming in real low.

I am mixing 3 gallons of RO water at a time:

15 ml / gal Coco A
15 ml / gal Coco B
2 ml / gal Rhizotonic
5 ml / gal cal mag

and this is giving me a 368 ppm reading

Now the A + B bottles say to use a maximum of 40 ml of each per 2.65 gallons so why would it be so low???

I am using the Hanna PH EC combo (HI9829) to take my readings and it is calibrated. .....But there is a little confusion regarding the adjustable conversion factor and beta (??) feature.

But when I take a reading of my tap water it comes out to around 500 ppms which sounds about right.

 

[treedup]

I am reading some of these other posts on Canna Coco feeding schedule and it sounds like 15ml per gallon is too high....but then why are my readings so low????

this is frustrating

Hi,

I can tell u that it can be impossible for your ecmeter read only 368 ppm with all that nutes...

I use 2 ml of A and also 2ml of B per liter...
And only for these my ec meter,hanna too, relieves about 800-900 ppm...

The reason can be:

-or your hanna ec meter is a chinese creap,or it is simply broken,(but u have already sayd that it is also calibrated)

-so I guess that the only reason it's that your canna nutes are out of date...(I hope that u understand what I'm talking about,sorry but i'm italian)...
So if it will be,the number of elements in the bottle are slowly coming down,disappering...

Hope I have help u...

I certainly hope that isn't the case. I just bought these a few weeks ago. The only thing I can think of is this ec meter isnt set properly. my EC reading is 686. shouldn't it be like .6 something???

 

[sketchy]

No, you are reading in part per milion
so your 686 are 0.686 ms and it is too low anyway...
My is 0.9 with low nutes than yours....

I think that the only way possible can be the old nutes...

You must to control the date that is written in the bottle...
I've bought months ago some soil nutes that my grower shop has sell to my like "fresh" but these was old like mine grandfa ass

Check the date...Hope the problem will be these and not the ecmeter...

Hi, 'night!

[treedup]

Thanks a lot for responding. I'll check the nutes....

but my plants are getting nute burn so I would assume I am overfeeding. I wasn't having this problem when I was using the Foxfarm nutes.

sounds like your meter is fucked up. take it to the store and ask them to test it there. if he says it works get a refund and buy a milwaukee

 

[treedup]

okay so I just mixed up some foxfarm nutes and the ppms are where they should be so I am thinking there is a problem with my Canna A + B.....

If I switch back to FoxFarm will this have any negative impact on my crop??

 

[eman]

are you mixing them right? first put part A into the water and mix it up and then put part B into the water. The 2 parts should never mix unless theyre in water.

 

[treedup]

yeah I am definitely mixing it right.....that shit is no good. I am not happy with my first run of the canna line....but I am willing to give it another go before I completely give up....

 

[NorCalFor20]

sounds discouraging to me i might stick to something like my foxfarm with a dripper.....

never had an issue with canna coco a/b
RO water is the way to start....

have you tried feeding them anyways with the solution you mixed?
as long as its PH'd properly i bet everything is kosher.

was the EC reading below 0.5 to? I always check both and multiply the EC x 700 to cross check the ppm reading but i watch my plants leaves primarily to tell me when they are getting too much....

speaking of low ppm reading though I have a friend using RO water and dumping in everything AN and his Nutridrip Tri Meter (or whatever it is) tells him at max hes pushing 800 ppms but no way - either his plants are hella sensative or he's pushing a lot of shit down his plants throats and the meter isn't reading it because they look burnt/over fed to me everytime.

maybe blinding your eyes to the ppm and jst using "the force" and watching the leaves isnt a bad idea??

My EC said it was 686 which makes no sense to me. I think I was all high one night and changed something on my meter. Is there a way to get the default setting on those Hanna Combo PH / EC waterproof meters?? I haven't been able to find much on how to use those things correctly. This is my first grow doing 100% coco so this is really my first time using a tds meter. I PH between 5.6 and 5.8 always

My plants were dying a slow and agonizing death. I have 4 master kush x sour diesels and 1 White Shark that are on their eighth week. The first 3 weeks I started with FoxFarm and everything was okay. When I added 8 new plants 3 weeks ago, I decided to go with Canna and like an idiot I switched my other plants also. Now I don't have a single healthy fan leave on the older ones and they are slanting.

I thought, at first, I messed up my meter because I changed the conversion factor. It really had nothing to do with that. It was the nutes all the way.

How fucked up is that?? I thought Canna was supposed to be the best stuff??

Still...I see how every so often you can get a bad batch....I am going to check to see if it is the A or B that's bad.....

My meter is reading the ppms just fine now with the FoxFarm. My last batch was at 1036 ppms with their recommended 9th week feeding schedule (without the additives).

 

[treedup]

And for the record, I am definitely going to give Canna Coco another try when I start my next round. I read nothing but good things about it in this Coco forum and I refuse to believe this current situation is a reflection on the over quality of the product line.....

...but if it happens again...

I got to 1.6EC with 40ml+40ml in 10L of 0.11EC tap water, so that's 16ml/gallon.
When I mix 20ml+20ml, half the above, I get 1.2EC. Funny eh?
40ml A&B Seems A LOT, and with this rate I'll be runnin out of nutes before harvest...
1L of A+B cost me 20€. With GHE micro and bloom cost would be the same, and running H3ad's 6/9ml per gallon or 15/22.5ml per 10L I'd be using so much less it seems more sensible...
I see peeps runnin much lighter with canna, I tried it and fucked my shit up. Enlighten me here please!

hehehe


canna can NOT be held responsable for this i think. i been using canna line for soon 7 years - thats a hell-a-lot'a bottles and i never ahd an issue.

there is only 2 options here, and trust me on this.

1 - your EC meter is gone to the heaven of electronic devices. if not so;

2 - somebody opened those bottles and mixed the nutes with RO water.

lol

i think its the EC meter if anything. if and when nutes go bad its possible to see sedimentation in the bottom of the bottle. i seen this happen before with hesi products after leaving a bottle for about 3 years opened in hot conditions. i mean i opned it and put the tap back on but i definetly contaminated it.

the break-down time usually is quite long.

but the funny part is that even when you ec meter is saying you got low nute dose you plants are getting burnt.. so this once and for all proves it can not be the NUTES - since if they would have gone BAD there should be several signs of NUTRIENT inballance - with a lot of lock-outs and ect.

its really no need to speculate.

its the EC meter

hope you got it sorted soon mate

hehe


sweetINC - HOLD ON! dont water your plants with that unless they are TOMATO/chile plants or something of similar characteristics.

Canna COCO is not ONLY made for cannabis - so the bottles state a possible EC range WAY PAST what is good for our Girls. some plants CAN handle it - but really you are feeding continously too much N and sooner or later you will have trouble. even if you have a monster outdoor plant that can handle the higher nute doses - i think its better to go a bit low not to charge up the plants with too much N.

deep green plants will allways give a bit less potent nugs. Nitrogen and THC production is not a good combo.

dont use more than 20ml A+B per 10 liters - - but have in mind you CAN give higher doses every now and then.

 

[Lazyman]

I had a meter once that would only show the last 3 digits of a PPM number, so 1368 = 368 on the meter! Just sayin it can happen, I think that one was a Hannah too, but it was years ago. Take a sample of your solution and dilute it with half RO water and see what it says.

keep it around for futre garden use, switch over to House&garden you'll be much more satisfied, there products aren't as diluted as canna's.

Thanks for that!
I actually backed it up to that yesterday (1.2EC) as I got to thinking that somehow the mix reaches a point of saturation where more nutes don't register on the meter... Really dunno, but half less nutes is the way to go, since 1.2EC is still in the comfort zone. I've been upping the nutes for two weeks, giving much lower doses periodically.
I sorta had to, N def drove me to it. Everything is cool now, though, growing like mofo!

NEW Q for anyone wiser than myself:
I flipped to 12/12 two days ago, any feeding changes needed? Only running A&B and pk13/14. I'm wondering since a&b have a high N compared to P and K. Will coco counter this cuz it holds on to 'em?

 

[bonecarver_OG]

what?? are you giving PK13-14 after 2 days of 12/12?

thats not the idea.

during stretch the plants pretty much use same as veg nutes, but a slightly higher dose can be given to let the plants have some extra N for stretch.

PK 13-14 i dont think its a good idea to give untill the plants have well developped budsites.

giving PK to early can definetly mess things up big time. wait untill 4 weeks or so..

peace
