Unofficial Coco Coir Growers Thread

[Kenny Lingus]

THX GM! Yes I'm flowering, and I'll try to take some pics soon. (I just remember the run-off was read incorrectly as I just measured the pit where it goes, and I had been flushing with dilluted nutrient solution for some time before it.

Plants seem very fine, except for a few having narrow dark leaflets that curl inwards under and down, like a claw or fang thing. Could be that I'm too soon boosting PK and bumping the 1,5 already is a little too much I think as my tapwater EC is nil...

Anyway, I'll try to take some new pic and close-ups tonight.

A big thank you to everyone for helping me out. A good flush and now a solid ph and they are growing so dammn fast. Here's some pics for yall. The table is at 8 days of 12/12 and the trees are on day 4 of 12/12. I'm really happy with coco now that I'm getting the hang of it. This shit rocks!!

here's a few more of my first attempt at coir growing (earlier ones back in the thread)-it's day 32 of 12/12. If the pics came out in the right order; the first one should show pots and buckets below the screen where there is one. In the centre and on the left, in bins, are K2 with 3Bubblegums to the right and rear under screens.

a pic looking up at Bubblegum growing through the screen
a wider view of the room
and the last 3 are macros of the K2 leaves and buds

the plants have been a bit underfed and while the Bubblegums have yellowed out a bit at the bottom-the K2s are still deep green all over.

I know when i want to give the plants their pk boost but have been a bit unsure how you do it in coir so have been giving half nutes half pk (to give ec 1.8-2.0) every other watering.

the other thing to remember about pk 13/14 is that there are a few different companies making their own version of this stuff. like we saw on your chart, which i also mentioned, one way is to start adding it in small amounts after 14 days of 12/12 till about week 5 or 6. i suppose a very nute hungry strain will like this way. but for my WW i get better results with a single dose added to about 5 days worth of tank water. i reduce the ec a bit and make it up with the pk so it's only slightly higher then it was. but that's again with my nute shy WW. the other point is that if your grow is not dialed in 100% adding pk will not do much. i have gotten my gpw without adding pk recently. not that i don't think it's a great product, but like you said Bramski, it must be used correctly at the right time in the right amount for a given strain.

when used on a nute hungry strain in the full dose on top of ec 1.8 it can help to make buds like 2 liter coke bottles. but if you give it to a nute shy strain in full dose on top of normal nutes you can end up with miniature buds. specially if you add it at week 2 of 12/12 and over do it.

glad to hear all is going well for you Dalton.

the safest way to use the pk 13/14 with the canna nute regime is to use it between 4 and 3 week to harvest. reduce your over all ec level by 0.2 or 0.3 then add the pk as indicated on the bottle. i add it to 4 or 5 days worth of water. then i go back to normal nutes till the last 5 days which i use to get all the N flushed out of the medium so the fan leaves go yellow before they are cut. it gives you a great tasting product. to keep the flush so short, i pump a whole tank full of water through the system 5 days before i want to cut. then i refill the tank with only water at ph 6.0 and let that run for the last 4 days. the most important thing is not to start flushing a plant that is still in the budding out stage. you want to have mainly milky and one or two amber trichome heads before you even start the flush, else you'll be cutting into your own harvest. never stop feeding a plant too early. unless there is no choice of course.

 

[Bramski]

Just noticed that canna has changed their dosing schedule for pk1314. They now recommend that it's used in the small fruit development stage of flowering, which is roundabout 15 to 20 days into flower for most <65 day strains.

Kinda makes sense when you think about it as the plant needs the potassium and the phosphate for bud prduction.

 

[gaiusmarius]

yeah i know i saw that new plan too. have not tried it out. i have used the other methode many times though. anyway, would be interesting to hear some feed back on the new way that canna is recomending. so now they want you to use the whole dose after 2 weeks of 12/12? seems a bit heavy handed, unless they hve reduced he concentration a bit? but i'd be most interested to hear how well the new way is working for people. canna does normally test these things well before the anounce changes like above. thanks for the info Bramski.

 

[Bongojaz]

i'm growing a very nute sensitive strain right now, endless sky. i hand water. any suggested ml. per gallon that i should use? i was thinking of using 2.5 ml. per 2.65 gallons. i guess from what i've read here that i should subtract that same amount from my regular nutes before adding the pk. hey dalton, looks like you're running out of verticle space. are they still stretching?

 

[EddieShoestring]

Gaius-
thanks for the info on pk application-it's useful.
One thing-i normally run GH Ripen for the last two weeks of a hydro grow-can you use Ripen in Coco? Any input would be apprieciated

not noticed the change in the Canna schedule-well spotted

cheers

 

[SmokeRings]

How often do you have to feed in coco again? And is it neccessary to feed/water to runoff?

 

[Kenny Lingus]

^^^@Bramski!

New Canna Coco schedule also recommends 5-10% runoff opposed to 30% as before.
That's the thing I'm going for, but my strains are usually in at 42-50days, and I start giving 50-80ml Canna PK at beginning of week 4 (when all budsites were established and most stretching was done) I also lower the regular AB-nutes so the total EC is only raised like 0.1, kinda like Gaius recommends (orat least as he does).
I discovered the ph had bumped down at 3,9 after adding a few boosters, so it could've been that fucking the upper leaves a little.

Too bad I haven't got the picctures of my leaves yet.

Jorge Cervantes says in his "Bible" that the dark, downcurling leaves that retracts its leave edges inwards and underneath is a possible potassium shortage and excess nitrogen compounds caused by too high sodium levels. But I've found his "Bible" to be unprecise and a little bit "easy" on the picture descriptions and case-studies.) The canna stuff should contain little sodium so I think this cupping could be my plants Sour Bubble genes combined with a few environmental irregularities. I have other plants that don't show this, and I have seen curling in the specific clones before so I gues I can get a good crop anyhow.)

Gaiusmarius: They have separated the bloom and veg cycle by development and not lighthours so you still use it a little latter than the third week. Depends on strain I think, but I try to count backwards from their schedule and work it from there.

 

[Dalton]

Your right bongojaz. I'm what you call "vertically challenged" They are between 18-20 inches now and I can let them go until 30 after that they will be getting to close to the bulbs. So I'm at day 9 of flower and they are definately still stretching. When should they stop? I was planning on getting some bushmaster as a panic button or maybe I can get away with just a screen. Hopefully i'll make it. They were about six inches after 2 weeks from rooting when I flipped em. I don't know what do you guys think?

 

[Bongojaz]

hey dalton, i just got some of that bush master as a free sample from this place. i asked around and it's supposed to stop them dead in their tracks. they sent me some other samples of the humbolt line. i won't use the bm but may try the purple maxx.

Day 40/PK13-14/5% runoff

Day 40/PK13-14/5% runoff

Here's a cupla pics of my little coco grow at day 40. Have just finished a weeks run of PK 13-14 dosed as per bottle instructions. Nugs have def "hardened up" this last week, have stopped the addition of PK now, will probably take these at Day 55.
From the start of this grow runoff has been 5-10%.

Have a great Festive Season.

Stay Safe. Peace.

 

[Father Time]

Looking great mate,
expext a barrage of questions as i get closer to starting up this grow.hehehe
Kindest Regards, FT

AussieStix: dam nice!!


my first coco run...

 

[Bongojaz]

hey jessee, what up with them bags of coco? is that something new? what sizes do they come in???
p.s.
looking gooooood aussie!!!

 

[Guest]

yah there new... its coco and back in one package... kicks ass!! 2gal

 

[yes_i_cannabis]

hey aussie...what r thoise hps's?600 or 1000??

 

[ICETOKER]

gausmarius, i grow in dirt (all-mix) using the full canna terra range. I am on day 65 of flower and i did follow the NEW canna chart. All i can say that it seems to work as the NL are much fatter this time around. Both yield and potency seem to be better. I fed them pk 13/14 only 2 times over 1 week. I did notice a little yellowing though but it doesent seem to have hurt them.

 

[axel neek]

I've amended my coco coir with about 1/3 - 1/2 EWC.
Can I still water frequently? or do I need to treat it more like soil now?
