Powder Nutrients for Top Feed DTW Coco

OneHitDone said:

CX Hydroponics Coco is a bomb formulation. Just expensive here in the USA and a bit difficult to source.
I have a lab analysis of their A&B I sent out when I ran it so have a pretty good idea why it works so well.
Main thing with coco is runoff

one of the sources i read (manic botanix who seems fairly credible) was pretty adamant that a coco formula by most nute co are superior to a general dwc formula.

i'm not experienced enough in coco to say yeah or nay yet.

I could be wrong, but I'm fairly certain the only difference between a "coco-specific" blend and a normal formulation is a little more Ca and Mg.
I think it's largely a marketing ploy.

could be for sure.

but like i said lucas is 1:2 micro/bloom and h3ads is 2:3 micro bloom and 1 g of epsom. so more P and K for sure and Mg

The 1:2 ratio would have more P and K proportionally than the 2:3 ratio
The 2:3 ratio has more N and Ca proportionally

I've not changed anything nute-wise after switching to coco but I do make sure the initial coco prep is good.

It's not simply the N : P : K ratio and it definitely isn'y "Cal-mag" built in.
It has to do with nitrogen forms

duh. i messed that up. you are correct.

quite a bit different by h3ad's numbers
So... when I was using a modified lucas formula... my nutrient profile when growing in promix was:
N 130
P 93
K 163
Mg 64
S 43
Ca 130

By mixing 8ml/gal micro and 14ml/gal bloom and watering with plain water every other watering...

In the coco, I am now using 6ml/gal micro and 9ml/gal bloom which gives the nute profile:
N 97
P 60
K 105
Mg 41
S 27
Ca 97

adding 1 g/gal epsom salts to the solution changes the numbers for mg and s to:
Mg 67
S 61

When I ran Lucas in hydro rdwc I had better results with the H3ad formula.Closer too the 2-1-2 ratio I think.
Others Ive used were more of 2-3-3 ratio witch caused problems when feeding @ 1.5 EC.

The 6/9 looks pretty good, maybe just a tad low on K
Where I think most get into trouble is insufficient runoff. Things accumulate over time. As along as the media is constantly being leached and maintained at what the nutrient solution contains as far as EC / ph the plant has access to what it needs even if one element is a bit low in the mix since it's coming in fresh constantly.
I know it seems wasteful to be constantly running off but it does eliminate nutrient related problems

The nutrient line concept is the same with powdered nutrients. Look at Mega Crop 2-part, Sweet Candy and Bud Explosion to see the ingredients you need. You are still going to want the control with a part A low nitrogen nutrient base and a part B Calcium Nitrate with Ammonium Nitrate 15.5-0-0. Along with a PK booster and a Vitamins/Extracts product and Epsom should round out the lineup.
The PPM rough numbers I go by along with looking at the plants are :
N 120
P 50
K 200
Mg 80
Ca 110
S 100
Fe 3
Zn 1
B 0.5
Cu 0.25
Mo 0.1
Si 0.1
Mn 0.25

Have not tried H3ad's formula for coco but used Lucas in Hempy's.
My friend who I have been helping with his grow since he started growing is using GH Micro/Bloom at 3/4.5 plus 1 gram Epsom and 2 ml CaliMagic. He was using 6/9 but would get leaf burn bad.
As I said I have been using Canna nutes at reduced rates and I water to runoff in the first cycle and the last cycle get an extra 10 to 15 seconds to insure a good final runoff for the light cycle. Getting very low leaf tip burn and good overall results.

There is a bit different chemistry in a proper "coco formula".
If you talk to the reps at GH they will tell you straight up - if your in a coco based media you could be choosing Cocotek over Flora Series.

Jack's 321 is awesome. I've ran most nutes companies and they are now my favorite. Super easy, super affordable. Ill never change it after this. I used the 321 and gave a lil extra in heavy bud. Also did ful power fulvic acid, recharge and carboload

It seems like everytime I do the bloom for first week of flower it stresses the plants and they turn a light green. Any experience with this?

You dont feed bloom nutes until you have blooms,Little buttons,end of stretch, then switch gradually say 50/50.

Do you know the jacks line cause if not you shouldn't have any input.

There is one week of bloom nutes during bud set and then you go back to the same nutes used during veg.

I saw powdered nutrients, I have 3. You asked why the light green,I answered.

Ill bow out while I tend to my green plants.

Cheers.

There’s no need to run 10-30-20 for one to two weeks like the schedule says. I run Jack’s 3-2-1 start to finish.

Thank you! I have been doing that after I noticed the issues. Do you know what the point is of the 10-30-20?
