H3ad goes Coco

[YosemiteSam]

Dhude...the main thing effecting the strength of solution one can use is lights, way moreso than strain. What kind of lights are you using?

6 is not the best pH to run for coco. It is much better to run in a range of 5.5 to 5.9 in coco. At 6 what happens is that Mg uptake is much better than Ca and when that happens Ca starts accumulating on the coco fibers due to its cation exchange capacity. When enough Ca accumulates Mg gets locked out, i.e. no matter how much Mg you add it will not get to the plant. Running the lower pH will allow Ca to be taken up by the plant along with Mg thus preventing the Ca buildup on the coco fibers and eventual lockout of Mg.

Try running 5.5-5.9 on your next grow and see if that does not solve your Ca/Mg problem. Unfortunately at 6 weeks in it is going to be impossible to solve this problem with your feed water...if it is real bad foliar feeding Mg may be what you need to try.

yeah dhude I have found 6/9 to be too 'hot' especially if I don't flush often. so i started running 5/8 with the flora but i've always supplemented extra mag. ive never had a cal def with it. recently i switched to a/n 2part, same ratios (6/9), but a little lighter, and i don't get overferted.

gl...

sam has a good point about the PH. i let my rez drift from 5.5-6.2

 

[robertmarley]

The only time I ever got any yellowing was if I didnt water daily..

Left for 4 days and everything was good no drought, except for serious nute burn and some yellowing of the leaves from not getting fresh o2 every day..

proof to me that heads watering daily is the best

 

[bob00]

i had problems the first run with this formula plus it was my first time in coco,they looked overfed even backing off did no good and i would get a lot of yellowing.
i ended up at full strength nutes with a bit of calmag but i make sure i get some run off everyday.
the last two weeks they have been on drippers and have been fed 4 times a day with full strength nutes,and they are growing twice as fast now
i read through this thread a few times before i got it right,i think you just need to find what works for you

 

[Bobby Stainless]

I use tap water, 6.5/9, and water with little to no runoff, every other day or so. Ph'd to 5.7ish. I don't measure my PH anymore. I also use battery acid, which is much more powerful than the store bought ph down. MUCH cheaper to.

I have had great results thus far.

 

[Peat]

2 weeks in the solo cups.

Xplanted to 1 gal pots.
The yellowing does not seem to be progressing.

There's a couple more coco clones (& seedlings) behind them.

 

[krushonkush]

well, I will tell you that I really only know what I do...
I use just what is says the first run. b/c its a great base.next time around maybe
change some but really just like a week of 6/12ml before the drop or when I drop.
I'll just watch em if they start to eat leaves right after you drop the micro then you know to run alittle longer next time. I cant tell you to run higher ppms, they will. But I will tell you I feed the min. amount! I hate waste and going to the store!

Made this post last year.hehe I've played around with the mix more and tried Koolbloom. But, for me the good ol' 6/9 is the best. I ph around 6
Some get micro longer, some less. Burns oh soooo clean too
Thanks H3ad!!

 

[Peat]

That's good info, krushonkush.

What kind of water do you use?

No probs w/ Mg def?

 

[greenatik]

looking good peat. are u documenting your grow anywhere?

 

[robertmarley]

Have you guys had any experience with root stimulators in coco and noticed any worthy effects?

The only last thing I would like to work on really is getting quicker root growth if i could, not that its bad, but on my my current run the plants that had slightly more time to establish roots during transplant (solos to 2.5 gal) in veg before flipping to flower are the ones that are blowing up alot quicker then the rest..

was thinking along the lines of beneficials or maybe ewc tea

 

[hilbie]

some of the best looking plants ive seen are from people following the adivce on the bottle itself-

 

[krushonkush]

That's good info, krushonkush.

What kind of water do you use?

Thanks Peat. I use water right from my tap. If I remember right it has a low
ppm like 50-100 I could dust off the ppm meter and tell you for sure if need.
The 6/9 mix should mix around 6ph. Mg and other defs only came when ph was below 5.7 or not watering daily. Most of my ph adjustment is the bloom mix.
Another thing is the drop of the MICRO...this is the "bulker" it has all you need to grow MASS FUCKEM COLAS! You will learn the timing
by looking at the plant. Than the bloom finishes it off with just what is needed. Again I've run a lot of super,sweet,jumbo,mega,bud candy! You
may get it to work good but the pay off is to little for me.

 

[Bobby Stainless]

I am with KonK.

It is something you have to toy with a bit. I run my micro right up to the last 3 weeks, and bloom up to the last two.

I also add a little Bloombastic muhahahahaha.

You're doing it right, bro, and you are right about what you are doing...
Everything the ladies need is in there, in proportions they can easily use, no additives necessary... In fact, I'd be really tempted to call bullshit on anyone claiming some additive or another like a one shot dose of Koolbloom could add a significant percentage to yields, but why start an argument...

Anyone who wants to bother doing the experimentation like krushonkush has, will come up with similar results, and can join him in saying

On an interesting side note... I have moved again, and am somewhere where I have well water and lake water to choose from... I will be running them both using my 6/9 formula, and will keep everyone posted as to the results...

Also thanks to you all for your collective interest in this thread and for doing the experimentation and asking the questions which lead us forward...

 

[MacGyver420]

head thanks for this thread you got me to go coco from DWC
running your 6/9 mix and like you say the ph is right at 6 every time
i have just started this experiment i will definatly update on my progress...

 

[robertmarley]

Anyone else going from dixie sized cups to 2 gallong + pots? how long are you vegging to allow root growth before switching to flowering?

The ones I transplanted from 6 inch containers have done alot better than the ones that went from dixie straight to 2.5 gallong pots, trying to optimize my next run which will be in a few weeks

 

[Peat]

Kick ass!

Kick ass!

A little less than 4 wks since xplant from freshly rooted clone in peat pellet, to solo cup, to 1 gallon pot.
They were flipped to 12/12 around 10-ish days ago.

I've had a Blumat dripper in one for the last week.

 

[caljim]

Wow Peat! If those clones were pretty close at the start the blumat is really blowing the one on the right up.

Keep up the good work brother.

 

[Peat]

Thanks caljim.

To be fair, they were trained differently before they became a comparison project.
If you look close, you can tell the handwatered one has been topped.

Also for the first few days, I was constantly tweeking / picking at the dripper. Over that time, it delivered more nute sol than handwatering.

Lots of unkown variables too, I'm sure.

EDIT:
The main thing is both seem very healthy!

There's a little "clawing"
But, this particular lady ALWAYS claws a little...

And, maybe a little stretching.
They've been shaded by their neighbors most of thier lives.

 

[SirSmokalot]

yeah peat i get that clawing on 2-3 of my strains that dont like to much P early on. it always begins the lockout process i must correct with a good flushing or 2 before more leaves claw in the first 2 weeks on those strains. i give my girls light PK boost at start of flower to begin budset. my indicas love it but the hybrids do not!
i like the lil dripper jug. i want to do that on a couple new strains (sativas) off to the side on their own feeding schedual. looks like works great!
