H3ad goes Coco

[Thundurkel]

So my nutrient profile with CES Micro Bloom Mag Amped Plant Amp and Uncle John's Blend with GH Floralicious Plus and Florablend Vegan Tea is as follows and gives my a total of 535 PPMs which is pretty low right? Should I boost em up in week 4? I was gonna do was Rez does with a shot of Kool Bloom once a week but would it do better to run it the whole time at a lower dose? Like 1.25ml per gal of Liquid Kool Bloom 0-10-10 or Humboldt Nutrients Ginormous 0-18-16 ?? I want to get the most I can out my girls so let me know what you think bro I think I've come a long way and I'm getting this coco thing down!

N 102
P 70
K 143
Mg 59
S 67
Ca 92

9 days into flower and buds are starting to form so when should I up my Bloom to 15ml from 10? Or should I just leave it?? Thanks again Head my garden wouldn't look this way without ya!

 

[Grat3fulh3ad]

ratios look good to me... if you were planning to do a 'bloom boosting' dose of some type you should be fine... you doing multiple daily feedings?

 

[Thundurkel]

yea since I hand water I'm having to mix nutes 3x a day!! But yea when should I start upping the P&K??

 

[NCS420]

phosphorous becomes more available with lower pH.

Always more than happy to try and help out =].

Yeah figured that I should lower my ph. So i did to 5.6 from 5.8 and no more baking soda. I'm glad you said the same thing that I did. It's always good to get a second or third opinion. lol
Thanks again H3ad. They look great!

If you are going to up your p and K then during calyx building is the time...

 

[robertmarley]

robertmarley I'd up the bloom a bit and see how well that sorts it.

Thanks head, I was thinking of running straight RO and supplmenting calmag, but reading the labels on the micro/bloom bottles it says there's already a good amount in there. I ran DWC for years using lucas formula and never ran anything but that and RO water. Gonna try a 5/10 and see how that goes as i'm already in week 7. (going by what you said doing research it seems im having an overabundance of CA lockout magnesium and K)

Are yellow tips usually only associated with overfeeding N? I read over your other thread (plant nutrition and visual diagnosis) and it seems that not much nitrogen is really needed during the flowering stage.. that more of a 5/10 formula or even less micro would be sufficient

My plants were given more veg time on this run ( my second with coco ) but yet the overall height was shorter than last, could this be from the lock out?

hey head and everyone, just got a coco grow on the go and i am going to try your 6/9 formula. Very excited as everyone seems to be getting great results! got 2x SLH and 2x White Rhino, I will let you know how it goes. Just want to say thanks to everyone, especially head for this great thread, so much good information.

 

[mayorofthdesert]

Last go around (1st grow) I used the 6/9 ratio with AN's Micro & Bloom and had great results with 3 AK-48s which are now revegged, bushy and green & still on the simple 6/9 formula. The plants currently in flower are not doing nearly as well & I'm wondering if it's my introducing MagiCal & Big Bud to the mix or if it's the new strains (Nirvana Super Skunk & Ice) or what. Looks to me (but consider me 100% beginner) like a basic N deficiency & has since before the light switch. - Well, my memory is suspect, but I'm 80% sure the plants had yellowing lower leaves before the switch & addition of BigBud, but it's definitely accelerated since then. One plant has no real leaves left except at it's bud sites. Basically with these plants I've been adding a little MagiCal (2ml. per gallon - about half reccomended strength for use as a continual ammendment, about 1/4 strength if trying to address problem deficiency) and powdered big bud at 1/4tsp/gallon which I think is around 2/3 AN's reccomended strength. I add those two, then use the same 2:3 ratio of micro & bloom to get my ppms between 800 & 1000. I tried a pure RO flush for 3 days and I tried bumping the ppms to 1150 for a week, neither seemed to make any noticeable difference at all. I'm using 50/50 coco perlite, thoroughly flushed before use and an autopot bottom watering system. I shoot for ph 5.8, been making the rervoir about 5.6 & the next day it might be 6.0-6.2. I put it to 5.7 or 5.8 & it might slowly drift toward 6 but it usually stays good until empty then I rinse the revoir & start again.

My question for Head or anyone else who knows - You think the MagiCal &/or Big Bud throwing my ratios off too much or do I have other issues? I've been busy chasing design related stuff with the cabinet & haven't really digested too much about nutes yet. If I don't figure out what's going on I'll probably go back to the bare 6/9 mix next go-around and see how it goes, but that still won't tell me if it's the strains or the nutes since it'll be the revegged AK-48s that did great on 6/9 last time. Thanks for any ideas!

 

[GOOROO]

just wondering what kind of yields people are getting with this method.

My last run of was my worst yeild to date. barely a .25g per watt. now by no means am i blaming this method as there were other complications.

this next run is looking like it will yeild better.
so what is everyone else getting?>

 

[Thundurkel]

GooRoo I can't tell you really yet since I haven't got a full run under HID but it's given me the best results as far as calyx swelling check this out..

Same strain same coco mix and a week apart! The left colorful one is Pure Blend Pro and Kool Bloom and the right one is Cutting Edge Solutions Micro and Bloom 6/10 ONLY!!! I didn't know about dropping the Micro lol or it would've been colorful too but do you see the difference in calyx size? Same shit is happening right now so I know it's the Head formula being coco specific that's giving me better bud. My Oregon Grape bagseed pheno is doing it too

 

[GOOROO]

thanks thundurkel

good to see. yea i'm thinking i should have let them go longer but mites started to flare up at the end. Im guessing that the mites probably accounted for about 25% (possibly more) of my yeild. Next I would say my strains were not high yeilders. but still .25g/w is weak any way you look at it. my worst yeild before this was .6g/w with ebbn flow.

when mites feed they inject enzymes into the plant which retard the flowering process, much like mosquitos inject anticoagulants when they bite...

 

[AceHaze]

How do I avoid micronute deficiency?
Several factors...
first off, like you mention, is the nutrient stored in the plant...
Second, the nutrient cations held by the coco...
Third, the plants don't need loads of micros or nitrogen to swell and ripen flowers...

Arrived at the timing thru Trial and error, and collaboration with others I consider expert GH growers... Leaving the Micro in the mix any longer, I can tell it's still there in the smoke...

Properly flushing necessitates using up as much of the nutrient as possible that the plant has stored, so you have to time the removal of an element based on the time it takes the plant to metabolize all of it's stores...

As far as yield 'losses'... I'd say 10%... but that's somewhat an illusion as well, since I'd much rather have 10% less of a clean burning top notch product, than a few extra ounces of a throat burning harshness...

Hi!
First of all: Thank you so much 4 sharing your knowledge, H3ad!

I Just finished my 2nd run with coco using the canna coco A/B, atazym, rhizo, pk , boost and bio bizz alg-a-mic. Although I flushed for three weeks with tap water (ec 0.6) my buds are kinda harsh and burn to black ashes (some strains more, some less). I couldn´t figure out, what could be the culprit here until I read your post about the micro being noticeable in the finished bud even with a flush of over 3 weeks. I succesfully used the alg-a-mic to deal with cal/mag issues, but now my idea is, that the Alg-A-mic, which contains a lot of micros, might be the cause for my harsh and badly burning buds?
So, Head, do you think think, that this is plausible?

(Feeding schedule: I water every to every other day, with ec from 0.8 to 1.4 at max (50/50 osmosis/tap water), ph is always 5.8/5.9, I use pk for one week during the 2nd and 6th week of flowering, rhizo till 1st week of flowering, boost all the way during bloom as well as atazym during the whole grow till flush)

Thank you for your input

Peace

Ace

Why not flush with RO?
Sure the weed is completely dry etc (not trying to be an ass), maybe it needs a longer cure?

Hey robertmarley!
I must admit, I was too lazy to flush with RO...but I will try it next time! Sadly, it´s not wet or needs a longer cure... My last crop cured for 3 months and the same problems occured!
I´m a little confused because even the alaskan ice, which had a 4+ weeks flush, deoesn´t burn clean!!

 

[robertmarley]

Gotta be the flush.. I had nute burn pretty bad on my first run and the bud came out super smooth.. almost organic, as head would describe. Flushed with straight RO ph'd for about two weeks then took them down

 

[inreplyavalon]

Greetings.
Anyone have any idea what this may be from. It is only happening on the tops and is very yellowish and light green.

The plants have been in veg for about a month now. They receive 6/9 with tap water that has a starting ppm of 100 and ph of 7.5. The PH is adjusted before feeding to 5.7-6.0

It is happening on a number of plants and a few different strains. I am growing other strains the same way with no problems. Thanks for checking it out.

underwatering and/or ph inconsistency(ph shift because of medium drying). if i don't keep my pots watered often, before they even start to dry out, problems like that pop up.

second thoughts would be a mag hungry strain(s) if its isolated to a certain few. but im sure underwatering is the real culprit because once again some strains will be more sensitive and bitchy about the coco drying out

 

[lysol]

h3ad,

When I water I shake it until all runoff is finished running off, to make sure the coco is not water logged, only saturated.

Up to what point can I keep watering multiple times a day before expecting a diminishing effect on results? I have noticed watering more than once a day makes the roots poking out of the drainage hole whiten up, like they do when lots of o2 is available.

You say you decrease the feeding intensity, and increase frequency, to speed up growth. What is the most # of watering you did in a day and noticed no ill effects and do you still go to 20% runoff each time? What possible bad effects can watering "too much" have if there is such a concept?

Thanks in advance

^ great questions.
