Hi my strain is blackberrygum im useing a coco mediam 40ml coco a n b mixed seprate to 10L of water hand waterinng as no resivour useing a ballast with 125w cfl light i i also use a 4inc exstracter i dont see mynproblem as others are ok

 

[Chris Scorpio]

How much nutes is that, meaning % of manuf suggested amount

And what nutes is it

Water pH?

Distance light is away?

Looks like nute burn, could be a pH issue

 

[Stem18]

Ph between 5 and 6 as i use drops to test ph levels i couldnt say exsacly untill i get home wich i could upload a photo. I use these nutrients as too early for pk13/14

 

[Diggler420]

I would just give it ph’d water an no nutes, if it is dry

 

[Chris Scorpio]

Always use less then the manufacturer suggested amounts

After the seedling is established start at 1/4 strength
Then move up to 1/2 strength and stay there

I agree it's to early for nutes yet, pH water for a week or so

Also buy a pH pen, a must for growing


How far away are the lights??

I had a ph pen but it broke so will order a new one should i add another 10L to each mix to weaken ot more? So i have it ready for them

Not sure what that means

What strength of nutes did u mix up, % of manuf recommendation???

I am not sure what the feed ratio is for the coco a and b nute. But 40 ml for 10l seems like a lot. I would fill a jug full of water and take it to your local grow shop. Ask them to ph the tap water and see if they will ph adjust it. Buy a bottle of the ph down and they would probably do this. See how many ml they put per gallon or liter. For me, I add 2 1/4 ml per gallon of gh ph down, to get me at 5.9. Then, when your ph pen gets here you can check it with the 1/4 to 1/2 nite ratio

 

[Stem18]

I thought the same but i guess instructions r just a guideline i use ph indicater and ph up and down and 18hour light 6hous dark

 

[Stem18]

This is how i mixed but not give the plants any yet as im not 100% sure to follow that instruction dilution ratio 1:250

 

[Chris Scorpio]

Never go full strength

I'd toss that and start over in a week or so

Ya need ta do some math

Figure out 1/4 strength or 10ml per 10l..... Or 1ml per Liter

After about week 4 or so, dbl that and never change

 

[Stem18]

Thankyou ill give it ago and ill update you cheers

 

[GrizzWald]

Why don't they say 4ml per lt? What's the ec once nutes are mixed?

 

[Stem18]

What do u mean ec? My set up

 

[SOG001]

You are using the wrong ratio you are using the ratio for Rizotonic not Canna A&B you rate should be 15ml per 10 L
Go to the Canna web site and under grow info you can get the proper feed schedule use a ph meter to insure the solution is in the range of 5.5 to 6.2 with 5.8 being the optimum the plants need to have proper ph'd nutrients to enable them to use them as seen on this chart

if your nutrient are out side of this range the plants are unable to use them
Because your plants are suffering you will need to flush them with plain water ph'd to 5.6 to 6.0
Another thing are you watering to runoff? coco is hydro and needs to be watered to a run off of 20 % you can't overwater in coco you have been to my journal and seen my results using the same nutrients you are using. ge the best ph meter you can afford and an ec meter will take all the guesswork out of how much to mix with a little trial and error.

 

[GrizzWald]

Dont know how I posted that on this thread was early in morning

 

[SOG001]

You in your second grow are you? Black and White... You know it all or do you just like to make statements that you've read?.

Who are you referring to?

 

[GrizzWald]

What do u mean ec? My set up

Electro conductivity... Which means nothing to me but it's the reading of the concentration that the nutrients have been mixed.. lower ec, weaker dilution, higher ec, stronger...
