Calling Weezard - Coco Questions

[ledtime]

Weez,

I think I've had enough with soil. Right now I have three plants that out of nowhere are having what I think is PH spotting. Rust colored spots on the biggest fan leaves. One one of the plants, even after flushing the oldest/biggest fan leaves are dried and curling up bad. I saw some tiny spots this morning on a white widow plant that has been spectacular until now. I think I would like to go coco on the next run.

On to the questions:

1. How do you set up your pots? Hand water or have a drip system?
2. Canna Coco nutes correct? A + B?
3. I have an RO system, so how much Calmag do you recommend I add to the water?
4. What sort of watering frequency should I expect?
5. Is there a particular feeding schedule you could refer me to, or go right off of the bottles?

I've really reached my limit of patience with the soil. Last two grows have had crazy PH problems in flower. I'm very disappointed this round as I was really looking forward to some stellar sensi star and white widow. Doesn't look like I'll get a nice yield at all.

Hey ledtime, I'm not weezard but I'm 3 weeks into flowering my first time growing with Coco and can spit a few things I learned over. We really need a Coco sub forum or something.

How do you set up your pots? Hand water or have a drip system?
I started my seedlings in red solo cups with coco and just watered every day until run off. I poked 5 holes the size of a pen in the bottom of the cups. Nutes were at about 1ml/L of Canna Coco A and B.

I have an RO system, so how much Calmag do you recommend I add to the water?
At first I experimented with RO water but didn't have CalMag+ and immediately after 2 weeks of vegging saw some issues and switched to just tap water + nutes + pH down. I was however told at my hydro shop that I should add about 4ml/Liter of CalMag+ to RO water. Also don't forget to correct your pH.

What sort of watering frequency should I expect?
I water everyday with nutes with atleast 10% run off. I only flushed once in the entire cycle so far and that's because I didnt' pH balance from the get go. I will do 1 last flush during my last week of flower.

Is there a particular feeding schedule you could refer me to, or go right off of the bottles?
If growing with Canna nutes goto: Grow Guide | CANNA UK and end up with something like this:
Then just ramp up your dosage from 1/4 to about 3/4th of what they say on that list. I tried to ramp up to what they reccomend but ended up burning some leaves so I backed off to about 3/4th and things are looking great!

As for my current grow, it started off okay and then got worse but now is looking great. The problem I had was with pH, I never adjusted it. Try to get your pH down to 5.6~6.2 and you'll be solid. I saw my plants perk right back once I got the pH dialed in.

Check my sig for my first grow using Canna Coco and Canna nutes. I'm 3 weeks into flower :hippy:

I'm as well 2 weeks into flower on coco...I love this stuff!!!! I started everything out in solo cups and then moved them into 5 and 7 gallon smart pots (they are made of the same material as a weed barrier in your yard). I am doing a drain to waste as well and I shoot for the %10 run off as well. I think Canna recommends %30, but that just seems a little over the top to me. Also Aquanaut, I was explicitly told not to flush coco with just straight water. Doing this raises your EC and also there is bacteria in the coco naturally that is septic to the plants and prevents disease issues that gets washed away with a water flush. I also water on a daily basis, and nute with every watering. Nutrients I use are Canna a and B, Rhizotonic, Cannazyme, Boost, and pk 13/14 starting next week.

I use coco aswell and I think it is a great medium to grow in. It's nice to work with and I like the ability to control exactly what and how much food your plants get. If you do get nute problems they are easier to correct than in soil. I use pretty much the same watering schedule and dosages as Aquanaut and Jord0713 I am very happy with the results I have got so far.

:jointsmile:

[aquanaut]

Maybe if we make enough of a ruckus one of the admins will make a CoCo sub forum. :hippy:

@Jord0713 - How do you like Boost? I'm currently only using A, B, and PK. Deciding if I want to grab Rhizotonic, Canazyme, and Boost for my next grow. I read mix reviews on Boost.. almost seems like the star line for Canna is: Coco A + B, PK, Rhizotonic, and Cannazyme. Boost just costs so much!

@PhatJay - Howdy!

[ledtime]

Thanks for the info guys. Watering everyday with nutes huh? Seems like you would go through quite of bit of A+B at 10mL per gallon. Is there any problem with mixing and PH'ing these nutes ahead of time? How long can they be mixed before being used?

Oh, I did send a request to the admin to add a Coco section. We'll see if they do it.

[aquanaut]

Yeap, my hydro shop said nute everyday and I have no problems with it. I tried the 1 day on and 1 day off but saw slower growth. As for pH, with my faucet water I need to add 4 drops of General Hydroponics PH Down per 1.75 liters (my water container).

I usually use all my nutes in a day and have little to none left over, which I toss and make fresh again every morning. I add water, ph down, A, and B in that order every morning. Sometimes I add a drop of Superthrive but can't really say it does anything, can't hurt.

:hippy:

[ledtime]

I read somewhere that you need to let the canna nutes sit for about an hour in the water before PH'ing. It lets the the PH buffers stabilize?

Hey ledtime, I'm not weezard .

You'll do, brah!
Great post!

I'll be there.

Howzit LT?

I've never used Canna Nutes.
Jus' some cheap kine Dyna-gro.
Seems to do the job.

1 tsp. per gallon with my tap water sets the PH dead center. 5.5 - 5.6.


You are getting very good info here.
All I can add is.

Use good quality coco. I like Botanicare.
And taste it before you nute it!
It won't hurt you.
If it tastes salty give it a pass.
Flotsam coconuts are cheap and plentiful.
The good coir is made from inland nuts and thoroughly rinsed.

Never let it dry completely, it's not soil, there's no second chance!

Checking moisture is best done by lifting the pot.
Not as heavy?
Time to water.
It is very hard to drown a plant with coco.
I germinate in it, clone in it and bloom in it.
But, I don't re-use it with the med garden.
It goes to the vegetable garden and in the ginger patch.

Welcome aboard. You will be pleased.

Aloha.
