The Official Canna Coco & Nutrients Thread

Most brands of coco ate shit bcuz they do not properly rinse before selling and it has way too much salt.
If u buy any coco coir besides Canna then test the run off ppm... It should be around 60ppm... But I've seen other big name brands have as much as 2000 ppm, and then they say coco sucks... Wrong.. Buy Canna or test your coco ppm for excess salts.
I use canna coco and line with ro. Last run I used 5ml a gallon call mag always every watering. I got awful lockout and potassium and mag were locked out. I figured from too much cal? This run I'm using no cal mag and hitting a slight mag def. I hear cannas made for ro then cal mag to 200. Shits killin me

I'm gonna go to 100 of cal mag and try to find the balance if this isn't it then idk what else. It alwAys starts a cpl weeks into flower also.

Then I would try 150.. maybe it was something else that caused your lock-out before? Or maybe your strain is sensitive to fertilizer... Try cutting back your base nutes a little bit... The coco should be able to handle 150 ppm of calmag as long as there is sufficient runoff... Just my 2 cents

I'm at 1.2 ec and on third week flower. I always get plenty of runoff. Whenever I try to go any higher I get mad high runoff. I'm used to flood and drain where I feed 2.0 in flower. Should I up my base? Idk why I'm having such problems. I really appreciate the help as well bro

Sky rocket and jberry answered right after your post. Start with a base of cal mag 150-200. And yes a and b thru veg and flower. In flower use boost and pk as well. I use big bud at beginning of flower. Hope that helped bro
Thankyou i understood the most part of it, would i use a cal mag product from start to finish? And do canna sell every one of these products and if so could you tell me the pacific names? Like i said i am still pretty new so im abit confused over certain things.. cheers dude.

I am in us and can not get canns cal mag products. In europe n uk I believe the canna has cal mag products. During veg plants use cal and mag and during first part of flower lots of cal and during last half mag. I just use general hydroponics calimagic. The coco retains calcium so you have to fill up its need for calcium before your plant can get what it needs. There's a happy balance somewhere in there.

Im in the uk anyway, i did hear cal mag was especially important if you're using soft tap water in coco, im sure ill figure the balance out on my own. Cheers dude much appreciated

It sounds like u may be getting a nutrient deficiency during the 3rd week of flowering everytime, and not a nutrient lockout.

Use the calmag... I assume you know that the calmag MUST be added (and mixed in well) to your water BEFORE adding your base nutes / additives.

Yes, adjust your base nutes because 1.2 ec is far too low for a plant that old... Also, once a plant is forced into bloom and starts going through the stretching stage, it is growing at a rapid pace and needs extra fertilizer (the highest EC of the entire grow should be used during the stretching faze), followed by a big dose of P-K (large PK dose around weeks 4-6, but cut back base nutes when using powerful PK fertilizer)

* You said your runoff is really high if you increase your ec, but how high is it... It goes in at 1.2 and comes out at what ec?

** TIP:
When everything is dialed in just right, then you will be feeding with "X" amount of PPM's and the runoff comes out at 50-100 PPM's less...
EXAMPLE:
I water with 1200 PPM and my runoff is 1100-1150 PPM's.

Whenever I get around 1.4-1.5 I'll start getting runoff around 1.7-1.8. I irrigate with droppers once at lights on and right before lights out. They are in 100% coco with hydroton at bottom. Maybe the buildup was excess cal mag bc I was using 5ml a gallon. I started adding 2ml last night upped to 1.4 and runoff was lower for once. Do you do any routine flushes like entering flower or anything?

I only flush if there is a toxic build up.
If u do flush.. then u should flush using a light cal mag solution... Like 60 ppm of cal mag followed by a light feeding.
The coco needs to fed with cal mag before it will release any calmag to your plants.. Canna already adds this buffer for you but it can be washed away with a big flushing and that can cause its own problems.
Wish I had more answers for u, but Im honestly not positive what's going on.

Couple of quick thoughts... It would be beneficial to wait for the lights to be on for 20min. - 2 hrs. before watering... And your last watering of the day should be 2hrs. before lights go out.. it's not beneficial to water right before lights turn off and may even cause problems.
Keep upping your EC , because I fear that low of ec during this rapid bloom growth could also cause u problems and effect your yield... PK timing is critical because if u miss the "PK window" then u can't really make up for it by adding a bunch at end of the blooming stage.

Fyi, Canna boost is sugar water derived from sugar beets , along with some unknown hormones that Canna won't disclose... But there are only so many hormones that it can be and definitely not worth the money unless money is not a factor.. I recommend using it as a foliar feeding 90% of the time if u end up buying it.
Peace
Canna Boost does not use sugar beets at all. Boost starts as a metabolic product from sugar cane with additives to stabilize the product, but they are not hormones. Over a 7 month process the boost gets fermented and broken down.

They must have changed their sugar source so they can make a bigger profit ... all the gallons of it that I bought years ago said it was derived from sugar beeets right on the bottle.
I think the main point is that it is a $500. bottle of sugar water.
No more hormones just means it is truely just sugar water and I bet using Cain Sugar saves them $$$.

From Canna Website:
Some of the active ingredients of CANNABOOST are derived as by-products from the production of bio ethanol and yeast, through the fermentation of molasses from sugar cane or sugar beet and palm. These by-products are called carbohydrates.
