Coco: Tips, techniques, and the facts you will need

[swaggersDlite]

Hey guys having a problem with my coco plants. They hit weight they look Hella frosty , but most of the have no smell . I'm using coco nutes with a few different additives. My soil plants reek , anyone ever have a problem like this ????

They should stink if you rub on or knock them about a little. Once you harvest and squeeze one they will certainly release their stanky aromas.

Try giving them some epsom or K2SO4.

I've harvested 8 already 2 stank but not like usual , and 6 other have no smell, ppl still like the weed , but I don't I need taste

I already have magnesium and potassium in there and sulfates too

I jack em up on sulfur at the end. Helps the taste and smell.
K2SO4 tends to give them more of a citrus profile than epsom.

Anybody know if I can use the liquid lime from Nectar (the ph up) to buffer my new coco? Or how much to use? I have a bottle sitting around and nothing to do with it.

Why would you want to buffer it up?
I use a lot of ph down but rarely need to raise ph.

And if I did want to raise PH, I'd use humic acids or liquid silica.

You're right, I probably wouldn't want to do that, although I don't know what the starting ph is. I just thought maybe I could use the calcium in it for an initial buffering. No biggie.

It's a good idea to buffer your coco with cal-mag but you also want to keep PH down.

Nectar for the gods nutes are different and don't always play nice with other products. I got a bunch for free and have only experimented a little...

Can I ask why you cant let the medium dry? As I've personally run coco for quite a while now at least 2 runs if not 3 (just hit a bowl so kinda foggy) And I let mine dry out beyond all belief I mean bone dry! Leaves are sagging and touching stems dry! I have never looked at my PPM or used my EC meter, the only nute problem I have run into was when the blue dream became root bound because it's a monster! Am I just lucky or are people trying to make it seem more complicated? I have 4 different strains running in coco all get the same treatment just slightly different amounts of nutes as required and I have some really really happy girls right now, Bluedream is over 4ft tall and still in veg! Must admit she is drinking the nutes now so will do a mega cloning and prune and flip her to flower!?

Have posted this elsewhere, but this seems to be a good spot for this.


LESS IS MORE

200 ppm of a + b for veg. is plenty.
350 ppm of a + b for flower is plenty.

CaliMagic/Canna A&B ratio
150 ppm/200 ppm = 350
100 ppm/300 ppm = 400
50 ppm/ 400 ppm= 450

Here is a chart the gives the ratios of Calcium in given ppm of A&B.
This Calcium information is purely based on a Canna schedule, using CaliMagic. Once you hit around 700 ppm, Canna base nutes, you no longer need Cal/mag additives.

This is based on slightly rough math but is very close to correct, in my experience.
A&B
3 ml/gal = .4 EC = 200 ppm with around 44 ppm of calcium
4.5 ml/gal = .6 EC = 300 ppm with around 66 ppm of calcium
6.2 ml/gal = .8 EC = 400 ppm with around 88 ppm of calcium
7.7 ml/gal = 1 EC = 500 ppm with around 112 ppm of calcium
9.2 ml/gal = 1.2 EC = 600 ppm with around 135 ppm of calcium.

I use GH Cal/Magic and I believe the recommended rate is 3.5 ml (1 tsp/5 ml)/gallon. I use Canna Coco's line of nutrients but I back off of their recommended rates, as I feel they are way high. For example, in veg I will add only 200 ppm of A&B and in flower 350 ppm. Now these rates do not give me the Cal ratio needed. You need around 150 ppm of calcium alone.....so even if when I'm at 200 ppm if I only added 100 ppm of Calimagic, only 75 is calcium so I would still be a tad short. In flower, I use RO (55 ppm of Cal/Mag), to this I add 0.75 ml Cal/Magic (68 ppm) and 0.5 grams Epsom (63 ppm) per gallon to bring my #'s to 131 ppm, below the 150 ppm needed, That's without the 55 ppm of the RO, then begin adding the base nutrients. But I have been working with this and it seems ok. I believe it has to do with the 55 ppm of Cal/Mag that is added back to my RO water.

pH of 5.8 and let it drift to 6.0 to 6.1. Drip Clean for the win, helps clean the root system of excess nutes and keeps you nozzles clean.

Hope this makes sense!

Hi

I am new to the world of coco, I've been reading many topics here to try to solve problems that I see I've done

I have made three runs with them and I always have growing problems, and reading here, I see that you have to wash the coco first? before putting the plants, with nutrient solution? if so, once we have washed it to stabilize the ph, do we plant the plants?

 

[JohnDee]

When watering coco, a runoff of 20% is recommended so buildup does not occur...do not top off as a habit.

What did you mean here...top off? Sorry if that's stupidly obvious.

Nice summary. I grow in coco and tend to read stuff about it when I come across it. Never to late to learn. Read once...stretching my memory,...may have been the AN newsletter. That perlite just occupies space...holds no nutes to speak of...andthat it's better to use just coco coir. They also make the distinction between coco coir, coco peat and the really coarse stuff which is harder to find these days. So they said...rinse rinse rinse untill all the really fine coco peat is washed out. You do not want it in the pot.

I definitely do that when I'm re-using coco...but I still use aeration. I use growstones because they leach silica.

JD

Thanks!!!

I see things that I have always done wrong, the first not to wash and prepare the coco,
I use the ugro perlite brand, in theory it is already washed, but it comes with a high ph and in this round I am having many problems and it can be one of the causes ...

According to the web, canna coco is already washed and ready to use? Or do I also have to prepare it? To save me future problems, I would just have to add perlite

I have been using Canna Coco for yrs and I still prep it before I use it. May be redundant but redundancy is a good thing.

Yes it is.

I reuse coco...and reused coco must be rinsed and buffered. So I have everything all set up to rinse and buffer. Mild enough weather here to do it outside.

So I rinse and buffer so all my plants have similarly treated coco for consistency.
