Anyone know whats wrong with my leave

Looks like much smaller pots. Maybe you should give the 20L pot a little time to dry out after your next feed.

Canna doesnt publish their ratios but i found this a while back. If this analysis is to be trusted, it looks like their A/B line has plenty of calcium in it already. That said, I can not personally verify the accuracy.

Where Is Canna Hiding Their Calcium?(the Truth Behind Canna Nutrients)

Hello fellow cultivators, Something has been bothering me recently, where is the calcium in Canna's Coco line? Every major article and research paper I've studied has emphasized a minimum of 1.5:1 and a common maximum of 3:1 or 4:1 ratio of Calcium : Phosphorous. Based on Canna's 'Guaranteed...

Ye if read and been told old that a few times, you read all sorts off opinions tho, but that pops up a lot in forums it's ment to have plenty,
It is for coco so would make sense, and you can get canna for soil, so the coco nutrients shouod be enough for coco I suppose

Why I add calmag is because about a year ago I was having bad problems with cal & mag deficciancys, but also I was new to coco and was ovwr watering as they say you can't over water coco even in the seedling stage well u bloody have many tiems lol
So maybe it was the over watering causing cal & mag and other defficcanys, and not actually lack of cal & mag

The 3 in my small veg tent whwre also on cal see andni 1.2e.c for a good while and went down hill and the stayed to get to dark green so I tried then without calmag 4 days today and they lightened up a tad not so dark green and started really growing fast, they whwre growing and drinking slow they not now tho

So I'm gonna hit these 8 in my big tent 1.2 with no calmag and wait till i get quite bad cal mag deficciancys if i do I'll then add it sod it, if done a few grows with calmag and only adding thst 0.2 of it, but always late flower the get N overdose even if I drop the base feed low, but in the last 2 week's flush the always explode in growth.

Also I seen this site before by canna
You can pick your water type see

Grow guide | CANNA Gardening USA

www.cannagardening.com

But if also read on other canna sites to take your water to 0.4 with calmag the telling you 2 diffrent things


That flush took bloody ages I had to use straight from the tap and use hot and cold to get water temps right then ph and I don't about 10x10L of water flushing them mad.
And I had to use a pump to drain the trays ad it's not drain to wast it's auto pit tray, ow what fun haha

I just finished flushing then about 40 mins ago I'm just about to go hit them with 1.2 top Feed no calmag and leave then dry a bit then as the been drowned lucky the quit big as the should drink it, if the where small that be a bad over water I bet.


I'll update you in a few hours or tomorrow sometime, Tomorrow night maybe as they had about 24 hours to dry a tad then


Fair play tour stick with me all way through , thanks :)

This flush did did it thus last year's e when I had bad problems, a guy off this forum called ( THCfarmer ) told me to it to reset the coco becuase god knows what's going on in the medium so fresh starting
He's knew his stuff he did



I'm gonna hit 1.2 because i would ve on that now in soil with a plant that size and I know in soil it be fine so shall see

 

[Ph 007]

A year or so ago I change from soil to coco, I changed nutrients and changed from hps to led and from auto pit to drain to wast was so much new stuff lol

 

[jguit]

Yea, 1.2 EC isn't terribly high at all.

Here is the back of the bottle and all the stuff in it see

It appears to have plenty of calcium.

 

[jguit]

This is calculated at their full strength recommendation of 10ml per gallon.

I'm running just about the same calcium/nitrogen ratio with Jack's 5-12-26 and PureCal CalNit without issues.

Lost me a little bit
Do you mean 5-1.2-1.6 not 5-12-26 im looking at the chart, guess that chart is your nutrients label off bottle?

So you mean your using jacks base feed and calmag and that comes to the same ratio as my a&b without calmag?
Or you mean your base is about the same ratio and then your also adding calmag on top with no problems?

What's cal nit?


I fed them 1.2 Out was just 0.4 I would of like to run 1.2 through them till out is the same but it's bloody hard work getting in their with a pump to drain the wast from the trays.
Do you think it be ok ,or would you run 1.2 through them till out was 1.2?

 

[Ph 007]

I think I'm slowly getting their lol my base nutes contain 2.4% magnesium
And 6.3% calcium so my base it's a has more than yours and your adding calmag and its workout about same as mine a&b without added calmag
^
Hope I'm right or I'm gonna look stupid;)

On mine their also another % next to them I don't know what what on that myself lol

5-12-26 is the NPK ratio of the dry salts i'm using (Jack's)

So you mean your using jacks base feed and calmag and that comes to the same ratio as my a&b without calmag?

I am using Jack's 5-12-26 and PureCal 15-0-0 CalNit (18% Calcium) and the ratios of Nitrogen/Calcium at the ratios i run them at are about the same as your base nutrients without additional calmag. (Jack's 5-12-26 (A) plus CalNit (B) is a base feed, just like your Canna AB)

Or you mean your base is about the same ratio and then your also adding calmag on top with no problems?

I do not use any CalMag suppliments.

Short for Calcium Nitrate (Dry salts)

I wouldn't have flushed them with the .2 EC tap water as you did. I mentioned above that this would happen! haha.. You stripped (flushed) all of the salts out of your media. You'll have to run your 1.2 EC input feed until runoff equals 1.2 EC

Your feed has 4.5% Calcium. My fertilizer are A/B dry salts not unlike your liquid feed. Same stuff, just more economical. The Calcium Nitrate contains the calcium (and nitrogen). I do not use a CalMag supplement.

Hope I'm right or I'm gonna look stupid;)

This stuff gets confusing. It took me a bit to get a decent grasp on it.

Gutted maybe I could feed 1 hight e.c in like 1.8 once and 1.2 day after think it will work? They gonna be yellowig soon then

Is it ok thanks that helps me a lot, I'll leave the calmag out then, I didn't out calmag in my 1.2 feed can't remember if I said or not.
Are your using is it RO water?

 

[jguit]

I would advise against feeding high to compensate. Get your runoff to match your input feed.

im running RO water.. correct!

Hay

Look ok today not a great deal diffrent only 1 day lol, they do look a smudge better, but they deffo drinking a little faster,

In just top fed to some run off in 1.3 out 0.4-0.6 lol,, should be same or 0.6 max init, but gonna just keep at this, I dropped room temps a hours ago to test them on 78-80f again for few hours

I wanna flick to 12-12 soon they are a week or 2 overdue they gonna be to big otherwise ;)

 

[ComfortablyNumb]

Led grow, temo is 80-82 humidity 60-70% strange uh it in range I think for the led temps

Use a no-touch thermometer and get the leaf temp, not the air temp.

 

[Ph 007]

Today looking much happier now
They been on room temp 80-82f and the leds dimmed to 75w and leds 50-55cm away from the plants since last night and all day today

Just a moment ago I just raise the lights to 65-70cm away and turned them up to 150w
and again I'm playing with room temps haha can't decide between 78-80f or 78-80f

I have been tracking leaf temps for a for a few days And 80-82f the leaf themps are about 77-80ish max if checked at this temps now about 5 Times on diffrent days or diffrent times of day and always the same
And if also checked leaf temps a few times on diffrent days at room 78-80f and theb leaves are saying about 75-77 and the odd 78
I also have a small veg tent with a T5 Cfl light and the are very happy and the leaf temps in them are also about 75-77 so my hun must be accurit, so I'm gonna keep at 78-80 in my led room for a few days now and go off them leaf themps and see if the look even better or not in 2-3 days
But the looking much happier now, well so far anyway, cutting the calmag out and thst flush I did
:) fingers crossed no more problems as the whwre flicked to 12-12 yesterday

 

[Ph 007]

Here are 3 in my small veg tent lights are t5 clf

They have been off calmag for must be a good 5+ days and been in canna fewd nutrients feeding 0.8e.c + my 0.2e.c tap water total 1.0e.c ph 5.8-6.0
And I must day this is the best growth iv ever had in coco to date no funny leaves no dark leaves like n over does and drinking well and roots have really taken off :)

I think the coco gods might have actually helpwd me out as shit is looking up hope I get no more problems as the last year or so has been strss full very stress full i hace gobe more bald im sure from the stress
