The Official Canna Coco & Nutrients Thread

[Abucks]

I'm growing white widow at the moment. I've read other growers feeding these guys without issue. I on the other hand have had nothing but problems since moving to flower.
Before I started using canna, I had the same questions. Every other nute line adjusts acourding to where you are in the grow. Cannas site has great info on this. I also emailed them about it, and basicly they said when you use their line, it is designed so the plant and coco work together and the coco only releases what the plant needs. They also told me that the coco controls the PH so that it is perfect through the grow. I did weekly 1:1.5 soil tests, and this proved true. Rootzone PH during veg was a constant 6 and during flowering 5.8. I think I remember reading on their site that the starting water should be between .2 and .3, and most of that should be Cal/mag/Fe. If the Cal is off it will interfere with N and P uptake.

What I don't understand about canna A+B is why they always have to be used together. For example, I currently have an N tox problem, but I can't dial back the N without dialing back the P and K. What if my plant is sensitive to too much N but will gladly take more P and K? According to Canna, the plants get the N whether you like it or not.

I used cannas feed chart for my whole grow. Started around half strength light feed schedule, and worked my way up to full strength heavy feed schedule with no burning, or ill side affects. I should mention I run co2 at 1500 ppm so this makes a difference.

Are you using tap or r/o water?

Interesting. I'm using their calculator and when I plug in my values, they get as high 1800. Can you link the chart you're using? Maybe I'm using an outdated one, or worse, a broken calculator.

Is this the one you're using?: http://waytogrow.net/wp-content/uploads/2012/09/Canna-Coco-Grow-Charts.pdf

I'm not using that site for my calculations. Try this ..... http://www.cannagardening.com/growguide

It's directly from cannas website. You plug in how much water you are using, ml or tsp, type of medium etc. Then it calculates how much nutes and additives you should be mixing up.

My base water is from a well, EC .3 and PH 7.2 I mix this with reclaimed AC and dehumidifier water to bring the EC down to .15 then ad Cal/mag to bring EC up to .3 again. That way I know most of the ec is cal/mag/fe. I'm going to invest in a ro system as soon as I upgrade my well pump and pressure tank this summer.

Good stuff, thanks.

Wanted to add an update. I was using the GH PH testing kit instead of a high quality meter. BIG mistake. Turns out my PH was way below hydro range and this explains all the problems with my plants. I got a solid 5.8 with my meter, and the GH tester was 7! So before the meter, I was PH downing into the 4.5 range according to the meter =\

I'm sure most of you experienced guys are golden when it comes to PH, but if any other newbies are reading this, don't skimp on buying a solid PH meter. Spend $60+ if you need to. Also started adding more CalMag to get my water from 90 ppm to 220 ppm before adding nutes.

I also bought the PPM truncheon. Definitely worth the money.

Here is a good resource for conversions if you're the math type: http://www.lenntech.com/calculators/conductivity/tds-engels.htm

Canna and tupur which is a Coco mix and I pull 2-3 lbs a light no problem canna is the shit I have a feeding schedule that's unbeatable

 

[Afgan King]

Here's day 42 of flower

 

[Afgan King]

Ohhhhh ya and I'm running at 2800ppms as we speak for feeding and no issues lol gotta love canna

This grow is my first one with Canna and I'm having significant N tox problems.

Have you had any issues with Canna and N tox?

Also, I've never gone above 1100 ppm total solution!

 

[Afgan King]

Not at all your prob feeding wrong the schedule I use one that has been built over 20 years here in Colorado using canna and Coco mix I use tupur but ya I never have a single issue my schedule is flawless company I used to work for made 120,000,000$ last year with this schedule and run over 60 different strains with the same feed I was one of the 5 who made the last adjustments to it

What lights are you running and your method of veg and grow?

 

[Afgan King]

1000w hortilux, radient 8 hoods, phantom ballasts,clone to 1 gal use mycos on transplant let veg 14 days under 600 then transplant to 7 gallons use mycos under 1000's slowly cranking all 4 in flower room on and starting up slowly then 14-18 days later everything full in their pots and time to flip here's a plant to see actual size next to co2 tank I top twice

Nice but did you run canna nutes and all of its additives? I'm curious because Abucks ran the whole canna line up minus the canna boost with good success.

 

[Afgan King]

I run it all no boost and add sweet raw and protekt silica

 

[Afgan King]

I've met the CEO he was here in Denver visiting the legal grows that use canna on 4/20 boost is nice but not needed

Thanks for the info man. I'll try one round without the boost to see how it goes.

Hey guys hope this is the right thread. Starting a new grow, a few C.O.T.C. Cash Crop autos. I have always used a basic FloraNova regiment.
Stoped by the store to pick up more and the man gave me a free bottle of CANNA start and CANNA A&B. Told me to grow it side by side with my normal setup he was sure it would make a new customer of me.
Normaly I wait quite a while before adding and nutes, so whats the deal? should I just fallow the regular CANNA schedule? How do I properly use the CANNA start. He also told me to use regular tap water. Is this correct or is he just blowing smoke up my ass????

Get yourself a pH pen first off. And an EC or tds meter helps big time too. Depends on how serious you want to get growing dope. The more involved you get growing cannabis....the better your end product gets. At least thats what ive found.

The Canna Start works ok. However, the Rhizotonic is what you really want for the young ones. I normally start them on Rhizotonic (15ml/Gal) until there are true leaves on seedlings, or for a few days on cuts. Then I hit them with 4ml/Gallon of both A and B, and then move my way up. By week two I'm usually at 6-8 ml/gallon and start adding cannazym while cutting my Rhizo back.

Canna Start is basically baby food, but it precipitates really easy from storage. If your starting water is under 300ppm, just use it. If you are not sure, bring a bottle of your water to your local hydro shop and ask them to test it. Canna is still the best nutrient line up in my eyes. The plants grow great and the quality of herb borders on organic with respect to flavor and burn quality.

The majority of greenhouse veggie big time ag growers have a "baby food" formulated. Its a good idea. Its not nesscessary with what we do but its ideal in the plants eyes.

This is what happened to me. I saw a video where a guy had really nice plants and he was hitting them 15ml/gallon every watering so I thought sweet, I'll do that. Turned my plants very dark green and caused all kinds of N tox problems.

I've read from other growers that with Canna A+B, less is more. Some even called for PPMs as low as 400 in flower. I think the chart calls for 1800ish at peak feeding levels. My White Widows are in the 3rd week of flower and even at half the recommended dose, the N tox got worse. Flushed again and then will fall back to 1/4 recommended.

Unless your running a super dialed growroom thats on point with all the fixins....and know your strains like the back of your hand.....please DO NOT give your ladies 1800 ppm of ANYTHING.

Once you use rhizotonic a few times and realize the ouch factor in its cost....you can substitute things. After yer comfortable running the nutrient line....change out Rhizotonic for BioWeed or BioRoot from General Organics. Tell me if you notice a difference.
