lol yea watch out for the pH down and up, I bought extremely concentrated forms, if I were to splash some on my eye Id be blinded for life

I just edited my last post so that the formulas would make more sense, but like I said try ignoring any reference to ppm, Ive decided the whole ppm thing should be boycotted lol, its retarded that they have two scales for ppm and usually the product doesnt tell you which scale they are working in. My ppm pen didnt even tell me what scale it worked in.

Thats going to be a really really strong solultion if your only using 1 liter? I guess your just doing this as a practice run?

You should always add the A first and then mix it in, then add the B, even waiting a few minutes between I have heard is a good idea. You will not need to use pH up, the only time youll need pH up is if youve used too much pH down and you need to adjust back up. Your at pH 7 right now, so you need to use pH down to bring it to 5.8
when adjusting pH its not a simple matter of "how much do you use", its a trial and error thing, youll need to start by adding a small bit of pH down, mix it in, see what it does. Then continue to do this until you have your desired pH. When you become familiar with how strong your pH down is youll be able to eyeball pretty quick how much you need to add. I can usually get my pH to 5.8 within three of four trials. Don't get too impatient with this or youll end up bringing your pH down to 4 or 3 and youll have to adjust back up again. It's always better to get it right the first time.

Something I have found extremely usefull for mixing nutrients is a small 10ml plastic medicine syringe. They give them away from free at the pharmacy near me. I pour my nutrients into a shot glass and then use the syringe to suck up exactly the ml's I need

also are you sure 1000 is the max ppm? do the bottles say what the max EC is?
My House and Garden nutes at max strength are 4ml per 10 liters(same as yours) and that gives me a EC of 2.0 or a ppm of 1400
You'll notice that 1400 is 2x700. this means that H&G uses the 700x ppm scale. In this case ppm=700 x EC

But there is another scale which multiplies by 500 instead of 700. In this case EC x 500=ppm. Its good to know what scale your nutrients are in. I just learned this and it has saved me from overfeeding my plants because my ppm pen was reading in the 500 scale and my nutes calculator was setup for 700 scale.

If your going to just use ml measurements then you shouldnt have to worry too much about ppm anyways because you wont be able to actually measure your ppm.

A good way to avoid confusion with the two ppm scales is just to avoid thinking in ppm at all. There is only one scale for EC so if you use that you cant go wrong. Right now you should be at an EC of .5 or .6

It says nothing about it unless you are on about "the ec of canna coco disolved in tap water varies between 1,2 - 2,3 mS (= solution EC + water EC)"
I'm guessing mS is maximum solution?
Any chance of a tip on how much ph up to add as the ph is currently at 7?

Oh, on the bottle it says say 6.0 is 10 times weaker than 5.0 so i was assuming that i would need ph down to lower the acidity by ten times from 7.0 to get it at about 6.. (5.

well then I wouldnt worry about ppm or EC, I like to know about it so I can keep track of my EC when I add other things in like Cal/Mag or Silicate, but for now it shouldnt concern you.
If 4ml is max strength then thats all you need to know. The starting phase for your plants should be 1ml, slowly working your way up to 3ml. You may never need to excede 3ml.

But yeah i had a struggle asked my dad to get me the smallest measuring jug and he got me one that measured in 100mls
so i wen't around town and wen't into a shop called boots which in england is basically a medicine shop and i purchased a suringe for childrens medicine which measured from 1 - 5 ml only cost me a pound bargain i'd say

By using pH down(an acid) you are lowering the pH and increasing the acidity.
if for example you were to start with a pH of 7.7 and lower it to 5.7. You would have just made the solution 100 times more acidic(hense why gotta watch you don't spash that pH down in your eye)

Just give it a shot and see what happends.

Btw are you using a pH pen or are you using a colour comparrison kit?

It's a colour comparison kit which came with the 1litre bottles of ph up and down.
It's temporary as money is a slight problem at the moment depending on how my meeting with this agency goes tomorrow i might get a ph pen straight away but i have tested the forumula and put it under my cfl as that is the light spectrum they recommend i identify the colour of the liquid under and it is light lime meaning ph 7.0 i'm not going to spend a hour or so attempting to get it in orange 6.0 which should be fine untill i get this pen
Yes i will be very careful it's hydroponic ph up and down by growth technology (which im assuming is the company which makes this) and it quotes how strong the formula is saying it will burn my skin, cause blindless etc... all the horrible things i don't really want to read but in my opinion it's worth the risk to bring up my "babies" lol
The canna coco product advises i leave it out in the open (like when leaving water out to remove the chlorein) for a couple of hours after i stur it all in to make sure it disolves properly so i'm going to feed my plants with it at about 11 o clock so in 4 hours, all of them are still looking healthy somehow when i got back this morning one of my plants the ww x bb had not just sprouted a new set of leaves to catch up with the candy kush it over took it but the candy kush it's lowest set of leaves (apart from the 2 round leaves) have not gone yellow but a very slightly dimmed green colour so i am hopeing with these nutrients they would have recovered within a couple of days.
One more question i have a problem with my tap water that the water company has not yet fixed where the water comes out slightly cloudy so i have been boiling the water in my kettle to make the water completely clean and clear then leaving it out for 24 hours, would this boiling of the water remove the natural 150ppm?

no it wont change the ppm but it will get rid of chlorine, which is bad for plants anyways.

Your plants are tiny right now... but I seriously dont think you should try to boil all of your feed water... Youll be needing to use ALOT of water soon enough...
I just fed my plants 20 gallons(80 liters) of solution and they arent even in flower yet. Thats for 7 plants

make sure you adjust as closely as you can to 5.8, feeding your plants with nutrients at pH 7 will be useless to them, the nutrients will not be absorbed by the plants

You mentioned you were putting 1 ml into 1 liter... I hope your not feeding that to your plants because thats 10x stronger than it should be.

I definately recommend a pH pen over the drop test kits. I tried using a drop test kit at the start and then I bought a pH pen, and I check my nutrient solution that I thought was at 5.8 and it was at 6.5
not good at all

How come it is 10x stronger than it should be?
it says 40ml for 10l of water there fore 1l 4ml is the maximum strength so 1ml is about right for my small plants?
please correct me if i am wrong i don't understand what calculation would mean i need to use 0.1ml per l

I have just put ph down in 2mls of it and stired it how long should i wait before testing the ph again? or can i do it straight away

PH is now 4.0 lol so going to attempt adding 1.3ml of ph up and see how it goes

Oh yea sorry I miscalculated that, I thought you were adding 10ml to 1 Liter.

Yea like I said its going to be a matter of trial and error getting the pH where you want it. so you should just add small amounts until you reach 5.8 otherwise youll go too low.

Once you stir the solution it should be a matter of seconds before you can check the pH... Just stir it up real good and its ready.

Sounds like you pretty much got it now, I'm sure your plants will be happy to have their first meal of their life haha
good luck

On a phone call at the moment wow i have a story for you...

Firstly can i ask what country you live in my friend?

I'm in Canada

Well this is a great breakthrough for the UK http://clear-uk.org/putting-peter-hitchens-and-kathy-gyngell-straight/ as currently you can get years inside for even having a plant or two

Secondly a little journal i was writing about my experience trying to get the right PH wow it took forever, i made it to getting the indicator at the colour of 6.5 but a brighter version so it would have been around 6.2

Just added the canna coco a and stired
Added the b then stired


Testing PH of the water
Liquid solution has come out light limeish (7.0)
Need to add ph down to lower the number of the ph so the plant can drink the nutrients in the water


An online friend dillestpickle said i should try to get the ppm of the water to around 400
Meaning to put 1/4th of the maximum strength which would make it 1000pm
1/4th of the maximum strength 250ppm + the natural 150ppm of tap water = 400ppm which is right for small plants
Canna coco says the maximum strength is 40ml per 10l of water so i calculated i am using 1l of water so 40ml divided by ten
is 4ml yet i want to use 1/4 of the maximum so i use 1ml of a and 1ml of b
yet dillestpickle is saying that i should not use it as it is 10x too strong...
waiting on a reply from him now to explain this to me as i believe he is wrong


Added 2ml of ph down + the ph solution wen't to pink (4.0)
Now adding 1.3ml of ph up to see if that will make it 6.0 (orange)


I am aiming to get a light orange around 5.8 as i am using coco but while i am using a test kit and not a pen
it doesn't matter for now i will just aim for orange 6.0


The ph indicator is now purple.. i am extremly confused lol but this is wayyyy to low acidity


Time to try again ph down, i'm going to put 0.5ml's of ph down in as the ph is currently 11.0
CHANGE OF PLAN just read on a forum only drops are needed so i am going to try 0.2ml's of ph down to see what happens.


After 0.2ml's the acidity is now at a ph of 4.0 (pink) AGAIN! so i'm assuming this ph up and down stuff is STRONG
Added literally 4 drops probably about 0.05ml's of ph up and it is still pink
Now i will just have to keep adding a couple of drops at a time i assume this is so hard to do as i'm practicing with a l.


Spent about 50 attempts, ended it easily by pouring id say about 100ml of up in and it reached 7.0 again
i then poured about 20ml's of down and it reached about 6.2 THAT WILL DO! before i go crazy

Just made another solution to feed them as soon as my lights turn on at about 5 and it only took me 5 attempts using little drops of up and down found it alot easier than yesterday thanks again for all the help i don't know if there is any difference in them since yesterday till the light get's turned on so well see i'm hopeful but i did check them before i wen't bed last night just in case they were in stress but everything seemed fine

Hahaha nice journal entry lol funny stuff

I don't know if this is true but I think if you fuck around with the pH adding so much down and then so much up and then so much down and on and on you might actually hurt your nutrients. all the extra acids and bases your mixing in probably arent a good thing, Id try to do it using only pH down and getting it right the first time, if you have to add pH up to fix it, then you know your getting impatient and need to try using smaller amounts of pH down.
Your right though when you try mixing 10 liters at a time its alot easier to get it right because 5 drops isnt so much

What I did was I filled the bottom inch of a water bottle with pH down and filled the rest with tap water, that makes it alot easier to measure out the pH down and not overdo it.

Your last comment you said you used 100ml of pH up!?? wtf? thats alot of pH up lol I would definatly not use that solution even if you ever get it to 5.8

Thats some really good news man! holy shit, whats a little community service really? thats awesome, I don't even know what the laws are here in Canada, I keep reading about all these guys in California who are "legal" and i cant believe it.. or you see these huge million dollar grow ops in videos on youtube, and they are "medical marijuana licensed". I dont really watch the news much, I must have missed something lol. I just plan on not getting caught, that way I dont have to worry about whether its legal or not
BTW you can do ALOT!!!! with 9 plants! haha good news

Yes i know, i was planning on getting a big 4pot drip irrigation system http://root2success.co.uk/index.php?main_page=product_info&cPath=6_64&products_id=935
It measures 79 x 68 cm's when my tent is 120 x 120 cm's so i should be able to fit this http://root2success.co.uk/index.php?main_page=product_info&cPath=6_64&products_id=937 big 9 pot system as it measures 120x 110 but there will be literally no space in there and more than likely no room for the plants that will be a horror trying to get light to the lower leaves

I might just start using huge pots and doing 4 at a time like i am now after this grow, see if i can get a lb of 4 plants that should last me a few months if i pase myself
