The Official Canna Coco & Nutrients Thread

[nas2007]

the strains that are really showing the purple veins are blueberry. the other three im growing are orange kush. they seem to not be affected as bad as the BB's are. i fed them all anyways. tap water at 200ppm + coco A n B 6ml of each and PH to 5.8. total PPM is around 400. hoping they come back but im sure they will as they just have to be hungry. will keep all udated. thanks for the help. also, how often should i be feeding these guys? it takes about 2 days for them to start to get dry. i read that i should always keep the coco moist. for theses lil guys what kind of feed schedule should they be on. what to look for?

with coco you want to feed with every wattering, start of low with the A and B some where like 0.5ml of a and b to 1L of water, and work your way up from there hitting 3ml of a and b if where u want to get to, but step by step , how many days are they in veg now? and post some pics if you can

i dont have a decent camera. the pics get blurry so not worth showing. i use canna coco and nutes with 2 gal smart pots under T5. temps are 79deg and 60%humidity. i started feeding them with a n b 6ml per gal and rhiz 15ml per gal. they seem to be coming back. tap water 200ppm with a n b and rhiz total out at 400PPM. Ive been giving them that every 2 days as to not over water. it takes 2 days for the top of the canna coco to dry. should i be flooding the coco till i get run off? the plants are small at about an inch tall and second set of leaves are coming out. this coco seems a little tough compared to soil. thanks for all the help, Johnbs8

John,
You may need to add cal/mag too. Also, you want to water when the pot has lost half of it's water weight. And you should get good run off to keep the tds low. I use more nutes than you and the plants love it! But just keep an eye on the plants and see what they need. Some strains can take more and others can't.
Keep it up and remember to look at the plants and read what they are showing you.
Lates and i hope that helps.

Ok, so canna's website says you can use rhizotonic as a seed soak to help promote germination but they don't have any instructions on usage that I could find...has anyone tried to use the rhizo as a seed soak and what were the results? Did you use straight rhizo or a ratio of water + rhizo? Thanks!

 

[puffenuff]

Also, if anyone has used cannaboost as a foliar spray during flowering, how much per gallon do you mix up and how often can they be sprayed with it?

Hi mate jberry gives some good advice about foliar feedin earlier on, way back thou, but some guy made a little grow guide from all the info on this thread and posted it, should only be about 10pages or so back!
good luck!

please can someone help me out...first time grow and im growing indoor with coco. the plants are 16days old and 8 days old. i have been feeding them every 2days 17ml of a&B in 5lites of water. 2.5ltrs per pot. i just read on my nute pack it says to feed 4-6 times daily.................am i doing something wrong??? please help i dont want to ruin my babys

4-6 times daily definitely would not make sense with a normal coco grow. It sounds like whatever you're reading is referring to some sort of flood & drain setup.

ah ok right, so am i feeding them too much if i feed them every 2days 17ml of a and b??

All depends on how long it takes for the pot to get dry. You dont want to let it get 100% dry, but you dont want to keep it soaking wet all the time either. The roots need oxygen. When the pot feels light, feed it till you get a bit of runoff. Remember never to use plain water with the coco. Feed with every watering.

 

[james gordon]

ok great thanks, also how often should i water? i mean it takes about 3-4days for my pots to become dry....also im getting a little bit of purple on my stems what could this be casued from? and am i feeding them to high of a dose with my nutes? they are part a and b from nutrifeild

If it takes 3-4 days for the pots to get dry, then you should water every 2-3 days. Purple stems and veins usually mean potassium deficiency. Make sure your temps and humidity are good too. Never used nutrifield nutes so i cant really help you there.

 

[james gordon]

how can if be deff when its only so young....my temps are constant from 78deg far-82deg far, but drop sometimes to 14deg cell at night.. how should i correct the deficiency? would i be better of getting a nute that i only have to use once a or twice a week? becasue on the back it says i have to feed 4-6times daily with 25ml per 10litres of a and b. but since im only using 5litres of water i use 17ml of a and b. only once every 2days though. so im not sure if im doing something wrong by under feeding them...this is hard no doubt thank you for helping me though i really appreciate it

So i'm pretty sure I overfed my plants on their first 'full strength' feeding in Canna coco using coco A+B.

I've attached 2 pics to demonstrate what this terrible event looks like.

My biggest confusion is I followed the Canna schedule exactly for a normal feeding (8mL/gal Rhizotonic, 10mL/gal A, 10mL/gal B, 10mL/gal CannaZym), this says it shoul produce an EC around 1.7, yet for me my EC was 2.5 !!!

So I watered it down until it was about 1.6, phed it back to 5.8 (the tapwater I use has pH 7.0), fed to runoff and this is what resulted lol.

This was Sunday, I just re watered them at a more dilute dose (of everything, rhizo, A/B, zyme) with EC 1.0 now.

If this brown edge shit isn't overfeeding, well sorry to waste anyone's time lol

Either way i'm a bit miffed at what I can tell will be quality nutes (the plants perked right the fuck up and had beautiful chlorosis except for this brownness that has been getting everworse). I guess I will just feed them by my own measure of EC and not the chart their website produces for you anymore, but thats a shame.

PS: Other info:
Plants are 3 weeks from seed. Small grow dresser of 10 CUBIC feet, 10 x 23W CFLs (which I raised quite a bit out of fear they were somehow magically burning them, causing this brownness. Of course as I expected, they weren't burning my plants). Temps about 75-80 peak end, 65-70 low end, 40% RH.

Medium is just Canna coco, though I did add about 15% perlite to ONE plant (the first pic), the rest of my plants have no perliteetc. just coco

Sounds like you were not using RO water, and your tap water already has a high base PPM. You will probably need to either cut back on the nutes, or get an RO filter. I had the same problem at first since the base PPM of my tap was around 475, but after I got my RO filter, everything was perfect. If you use RO water, you need to make sure to use a cal/mag product as well.

No, my tapwater has the 'average' EC of 'standard water', which is EC 0.4.

I do not want RO water, I am content with tap, and it eliminates my concern for calmag. Thanks for the suggestion, i'm just fairly confident knowing what my tapwater is that its not the cause.

That was a fast as response btw

As long as you've looked at your city's water report and confirmed that a lot of that are good minerals like calcium, and not bad things like fluoride and chlorine, you should be ok on that end.

What about your mixing procedure? Did you mix each nutrient into the water first, and not together? Did you make sure to add Rhizo first, then A/B, then everything else? Did you allow the mixture to sit for several hours before you used it, so it had a chance for the mixture and PH to stabilize, etc?

That's about all I can think of. Maybe someone else can throw in some ideas.

Well, I don't have a city water report, but I offgas my tapwater for like 24 hours before I make my plants drink (so chlorine offgasses)

I would NEVER mix one nutrient with another !!! haha

k, heres what I do exactly lol, I measure into a 10mL graduated cylinder rhizo, pour it in water, pour water from bottle into grad cylinder few times to clean it out of rhizo. Shake for like 1 min. Then I repeat these steps in this order after rhizo Coco A, then B, then CannaZym.
Then I pH it to 5.8 (also I calibrate my pH meter every time I use it, u can call it anal, but I call it standard procedure in my work heh)

The last feeding, which was the one that caused this I did let sit for several hours before re pHing and feeding. Today though, cuz I was in a rush I didn't let it sit for hours, i'm not too concerned, but you raise a valid point.

Those pics to you are def. of nute burn right?
