Coco Growers Unite!

[jberry]

my apologies if this was covered already (and i do need to go back and re-read this entire thread) - when flushing at the end when using 100% coco - how many times and how far b4 harvest?

also though - what if you wanted to go for the tops/upper canopy first, and then let lower stuff get another, say 5 - 7 days - would you just taper off nutes ike Zen suggests about 7 days out?

thnx

It is kind of a preference as to how well you want to flush the medium and how faded/deficient you like your plant to get before harvest.

One Time Flush:
It typically takes 3 times the volume of the container to completely flush the medium... So if you were using 1 gallon pots then you would likely need 3 gallons of water run through each container to remove all of the salts. This should ideally be done within a 10-20 minute period to qualify as a typical "Flush".

Multi Watering Flush:
When you spread the flush over a several day period then it is going to take several days longer to achive fading and it will likely take even more water... ie, you would likely need to water with 4 gallons of water over a for day period (1 gallon a day for 4 days) to get the same results as you would have if you used the 3 gallons all at once. Also, the coco wont truely be flushed until the forth day.

Once the coco is completely flushed then the plant will start to fade and become deficient over the next few days... it is up to you how faded you want the plants to get before you chop them.

You should also avoid harvesting right after watering. It is much better if you can let the plants get to the point where they
would normally need another watering and then harvest.

More and more people seem to be swearing by a ripening method where you leave the plants in the dark for around 36 hours straight before harvesting... The usually claim is that it increases oil/resin production (thc) like crazy. I could definitely see it causing some last minute stress which in turn helps ripin the plant and possibly increase resin production since it is in the dark period that the resins are formed as a protictive sunscreen for tomorrows rays... I'm not soo convinced it makes a huge notible difference but it probably can't hurt anything that late in the game and it seems possible that it may have some effects on the plant.


I typically take about 4-7 days for the entire proccess depending on strain and the ripeness of the plant at the time... I know your rockin Blue Dream which is one that I likw to flush/cure well or it can hold some hay smelling qualities... I would say a solid week and a slow dry for the dream.

Peace, -J

For rooted clones anywhere between 250 ppm to 650 ppm seems to be fine but just keep an eye out for deficiencies or overdoses at adjust as needed. These are all just basic guidlines and it is always recommended to do a little experimenting to see whats best for your environment and strain.

For growing in coco coir rough guidline:

Grow: 1.0 if using RO Water / 1.4 if using typical Tap Water

Grow/Bloom Transition: 1.8 (RO) / 2.0 (Tap)

Bloom: 2.0 (RO) / 2.4 (Tap)

Thanks again jberry once I get these jillybean out the way and I'm able to clone this Grapegod I have going from seed I will be starting a journal I hope you and anyone else who has experience with coco stops by.

JBerry, I started to flush my ladies using water boost and cannazym as directed by the canna grow guide. I submitted a few pics to fdd and he suggested they need another 2-3 weeks. So I re-introduced coco a & b, must of overdone it slightly as oneof my plants leaves have gone all clawed.

A buddy has told me to just use bloom and boost for the next few weeks, although, I'm not sure it's that clearcut with the canna coco range. I don't think coco b is the bloom nute.... Or is it?

I think the plant is clawing because of a N overdose, bearing in mind I have about 2 weeks to go, what solution would you say is best from here on in?

GH came out with an organc line......not sure about too much but look into it......think its new....

Hi guys!

Bit of a newb question here but i thought if anyone could help out it would be you guys. To cut a long story short im currently growing in canna coco with biobizz nutes. The water is phd to 5.8-5.9 and im currently running Ec at 1.6 with biogrow (as of last watering). The plants have seemed to be growing at a slightly slow rate and are now displaying some signs of deficiancies such as yellowing leaves and slow growth. I was very careful not to overfeed and started them at 1/4 recommended dose and upped this slowly. Only reason im feeding now at 1.6EC is due to the deficiancies.

Do you guys consider this to be a result of low nutrients or poor uptake? Also I did consider whether to supplement with cal mag due to the tap water EC being only 0.1? Ive been advised by a friend that humic acid may help the plant to uptake more nutrients and that cal mag supplement is a good additive is this a possible solution?

I would really appreciate any help with this matter. Ive posted some pictures of my babies below.

hey man what up? i dont know if this helps or if you even want to hear it, but in my own opinion i think you neeed to use the coco as the nutes you have or vice versa. i had to mix my canna nutes with b'cuzz coco because the store was out of canna coco and it was really time for me to transplant. well long story short pretty much the same issue slow, poor growth. i think, and this is just me that the companies gear, or buffer, or whatever their coco to have the best result with the same brand of nutes. just my opinion. now if thats all youve got i tottally understand, we all know how it is and how it can get. but i think you need to make a decision either your biobizz coco with biobizz nutes, or your canna nutes with canna coco. hope that helps, but i told you you might not want to hear it.

also by the looks of the edges of leaves(curling up), you might need to make your nute solution a bit lighter.
this for example is my nute stregnths for my canna nutes.
seedlings/clones .25ml per liter for entire two weeks
2 weeks veg gradually increase from .25ml to 1.5-2 ml per liter
first six weeks flower gradually increase to 4ml per liter
last two weeks decrease down to 2ml per liter(somewhat of a flush).
you can adjust it to suit you, but of all the different ways ive tried, ive found that it works for me.

Btw i generally increase or decrease by .50ml at a time.


PEACE!!!

make a decision either your biobizz coco with biobizz nutes, or your canna nutes with canna coco. hope that helps, but i told you you might not want to hear it.

man i completely understand, thanks for your help. TBH im a bit pissed off with these companies not including all the shit the plants need in their nutrient solutions. If Biobizz are saying its cool for people to use their nutes in coco then they should specify which coco. Ive tried to do this grow organic but ive now had to use an artificial calmag solution and fulvic. I just dont understand why they dont include this shit in their solutions?

This has really put me off growing in coco i must say. I think its a great medium to grow in chemically but until they tailor it correctly i dont want to be spending$$$ on different additives because the nutes are lacking.

also by the looks of the edges of leaves(curling up), you might need to make your nute solution a bit lighter.
this for example is my nute stregnths for my canna nutes.
seedlings/clones .25ml per liter for entire two weeks

Ireally appreciate the advice zen and ive beent trying to increse the nutes slowly, its just when i saw the yellowing leaves i thought this may be a N deficiancy so upped the feeding. Ive since thought that this may be a magnesium deficiancy as the plants seem to be displaying all the typical characteristics of mag deficiancy (Upwards curling leaves, yellowing at tips etc) I think this may be due to the lack of microherd in the soil.

Next time im really contemplating just using allmix/lightmix with biobizz nutes for an organic grow or canna a&b with the canna coco like you say. Im 100% with you that these are specifically tailored to the soilless mix

Thanks for shedding some light on this for me Zen

 

[jberry]

you should be able to mix the brands of coco and coco nutrients, but 100% organic coco grows can be a little finicky and biobizz coco is way overpriced and well known for high EC and even toxic levels of salts... But for the most part all the brands of coco should be buffered in similar ways, with a similar EC, so you should be able to use any brand of nutes as long as it has the NPK that you want to use and they are designed for Hydro, not soil.

 

[JRTokin]

Hi J,

Thanks for the info, Yeah im finding out very quickly how finiky this grow really is. Its absolutely crazy, ive got some strains showing deficiancies, some showing signs of overfeeding, its really been a nightmare trying to judge what the plants want because the environment is so unpredictable.

In your opinion would it be possible to change nutrients at this stage to something else more suited to the coco grow? Ive had nothing but problems from day one with these plants. Slow growth, discouloration of leaves, leaves curling etc... I just want healthy plants!

Im quickly finding out that biobizz nutes + coco = bad idea!

Is there anything i can do to rescue this grow?

 

[JRTokin]

Ok well as a little update i managed to take both the EC and Ph for my four plants run off today. Id previously been treating this medium like a soil grow and watering every third day but i think i will be watering every day to waste from now on instead as the PH and EC both seem very high. EC is between 2.1 on the utopia haze to 3.2 on the g13 haze. Ph is between 8.1 - 8.2 on all four plants.

I know this is rediculously high at the moment. Is there any ways which you could reccomend that I could rectify this problem?

Im sure this is due to the fact that i have been watering every third day and not run to waste. If it comes to it and i have to flush the medium what is the best way to do this with coco?

Ok sorry guys just read your previous posts on flushing! Doh!

Thanks
JR

hey guys ive notived that when my girls start flowering im getting yellow tips on the end of the leaves and the new bud leaves.

i use the whole canna line up except boost. i also add budmiester which is like gravity it shorten internodal stretching. i feed 3 times a day Ph 5.8 and im growing in 30 gal pots.

 

[JRTokin]

Grow: 1.0 if using RO Water / 1.4 if using typical Tap Water

Grow/Bloom Transition: 1.8 (RO) / 2.0 (Tap)

Bloom: 2.0 (RO) / 2.4 (Tap)

So i take it the 1.6 i was previously running at with the biobizz was overkill? My tap water is at 0.2 EC does this count as RO or how should i alter nutes fr this EC?

Oh and ive ordered the Canna a and b today. Bit pissed with the biobizz range. May use it for a soil grow

 

[edsthreads]

I love Coco, I'm currently on approx my 5th grow using it & am recycling the Coco after each grow with great results..
Wish I had started using it earlier! it's a very versatile & forgiving medium

 

[JRTokin]

Having looked around online im beginning to get the feeling this may be nute lockout due to high patassium levels.

If i understand correctly coco alreay has a lot of naturally occuring potassium. Could it be that im overfeeding these ladies way to much potassium and limiting their nute uptake (im thinking specifically Magnesium and Calcium)?

The biobizz grow formula comes in very heavy on the potassium at an NPK of 8-2-6. This is double the K which is in the canna range!

Having flushed im now really tempted to use the nutes i should have used in the first place instead of trying to reinvent the wheel

So until Biobizz sort out their nute formulas I cant see how this can be a safe option in coco.

 

[jon blaze jr.]

yeah coco! recently made the switch with great expectations and pretty descent results. Great quality (not complaining about) but the quantity was mediocore. I'm using canna coco straight with the canna cogr nutes a+b, rhizo, cannazym, pk but not till week 5-7 (good? not good?), a touch of big bud and some bloombastic sprinkled in. I am also foilaring the boost every other night at lights out. I am only watering once a week in flower and maybe every week and a half in veg. The ones in flower are in 5 gal the veg range from solo cups up to 4qt to 5gal. All of them seem to never need water or feed for that matter. They grow great in veg, look good in flower but not getting the yield. 8 plants per 1000 watt. temps are good. i veg for 45 days transplanting into the five gal after 21 days. I was told get bigger pots (more root more fruit) but i think the guy just wants me to buy more media from him. U know how that goes. Anyway i guess my question is what can i do to get the bigger yields? The pumping of the waterings more then one time a day seems like a waste of nutes especially if u are draining to waste. Can u reciruclate in coco? I read most of the thread but damn after 50 pages my head started spinnin. If these awnsers are in here sorry for the double question. Thanks again if anybody can help J berry especially

Hi all,
I am preparing for my first grow and I have been reading about coco. Unfortunately canna is not available in my area. There are several hydro shops near me and one has a good brand of loose rinsed and buffered coco coir. My concern with going with coco is the cost of the nutrients.

Background: Things are still settling a bit on design, but this is where I am now. 3x3x5 grow box with 400w HPS with possible CFL supplement. 2 white rhino and 2 snow white. All for personal use. I would like the best, fastest, easiest crop I can get and coco seems to fit that.

I have not priced the coco specific nutrients, but from my reading in this thread it sounds like I will need quite a few and it could get expensive.

Any rough guesses on costs?

Any tips on sources to save $$?

Peace

 

[down by the river]

Ok, I priced the following online:
Canna Coco Nutrient A & B - 1 Liter
Canna PK 13-14 - 1 Liter
Canna Cannazym - 1 Liter
Canna Rhizotonic - .25 Liter
I can purchase these 4 products for $100 shipped to my door from Green Coast Hydroponics.

Should this be enough for 4 plants?

Missing anything?

I have read about not mixing nutrients from one company with coco from another. but if I purchase a quality coco coir (sorry forgetting name right now) I should be able to use canna products right?

 

[LeeroySlim]

it would depend on how long u vegged for, and how big the pots are.

 

[down by the river]

Ok. If I use 4 3 gallon pots and veg for 8 weeks (these numbers are off the top of my head-please let me know if I am off), then would I be ok?
