GH Flora Series Micro/Bloom-----6/9. Humic 12 at every watering from sprout to flush.

your chart confuses me, mind explaining it a tad more?

Sure. I made the chart so a grower can try various combinations (in terms of application rate) of the listed fertilizers to find what they think is ideal for their plants, in terms of elemental ppm, total ppm, ratios of 2 elements and relativity of 3 elements (ex., K|Ca|Mg).

Ex., one could add up say, the ppms from 6 ml GH Micro, 5 ml GH Grow, 8 ml GH Bloom, 2 ml CalMag+, 3 ml ProTeKt and 1 g Epsom salt (or other combinations thereof); and then find ratios, etc. All the fertilizers need not be used; ex., one doesn't have to use ProTeKt or Epsom.

In that screen shot the blue highlighted columns are my current test mix (re application rate per gallon) and the relevant ppms of elements from the fertilizers at the listed application rate. The green highlighted column under "Totals (ppm)" lists the total elemental ppm of my current mix when all ferts are added together. The other green highlighted column under "Ratios (":1" is assumed)" is the the 2 element ratios (ex., NO3:NH4, NO3:S, K:Mg, etc.) as well as 3 element relativity (ex., N|P|K and K|Ca|Mg) of my mix as compared to the same from the pH/Lucas mix. The orange highlighted text/numbers is the total ppm of my mix per element as compared to the total ppm of the pH/Lucas mix per element.

My current mix follows:

• GH Micro 5 ml/gal
• GH Gro 5 ml/gal
• GH Bloom 7 ml/gal
• CalMag Plus 5 ml/gal
• Pro-TekT at 2.5 ml/gal or AgiSil 16 providing ~29 ppm Si (I can do the math for you, if you plan to use AgiSil) or Dutch Master Silica at 7.5 ml/gal -- add the Si source to water first, then pH adjust and add other ferts.
• Epsom salt 0.5 g/gal (use hot water and shake or use blender to fully dissolve)
• Boric acid 0.015 g/gal (you can get human-food grade boric acid at a pharmacy for cheap)
• Fulvic acid at 15-30 ml/gal ("Ful-Power" from BioAg is by far the best, it can be found here and here, etc.)

Did that help explain the spreadsheet?

yes! explained it very well actually! curious why you use epsom with cal mag...

and you reminded me of fulvpower, have to grab some of that today....

and with that amount of calcium, you don't have have phosphorus lockout?

I use Epsom salt to increase Mg and to reach close to my goal K|Ca|Mg of 3|2|1, as well as my goal K:Mg ratio. Also, the extra S is welcome because S can be a bit lacking otherwise.



FWIW, a buddy told me he found the source of GH Flora Series ferts; the company that GH buys from wholesale and relabels under the GH brand. Buying from that company direct saves a good bit of money my buddy told me. I am not 100% sure he is correct about his claim, but I have no reason to doubt him. I plan to call up the other company (not GH) on Monday, and ask if they do indeed supply GH with their Flora Series wholesale. If that is the case I will order Micro, Grow and Bloom from them and have it tested at a lab to verify label claims. I would prefer to save some money on ferts if possible ...

Nope. And AFAIK a ratio of P:Ca isn't too much of a concern in terms of plant uptake; unless you mean by formation of insoluble P-Ca salt? If that is what you mean, I add citric acid to lower pH which will also help dissociate P-Ca into P and Ca (as soluble forms of those ions); as well as help prevent formation of P-Ca in the first place.

interesting.....

i think there cheap enough though, think im getting 6 gals of all three in the $240 range right now, 1 micro 2 blooms.....

compared to other companies like the yellow bottles,,,,,,

citric acid? can you explain, im finding this very informative.....

also, is your chart for all mediums, or what your working with?

 

[spurr]

@ Krunch,

Below are two posts of mine with pics of my current grow (GrapeGod) using that mix. Other growers here have tested my mix, and are testing my mix, and they all have gotten great results, better than via FNB, pH/Lucas and Head formulas. This grow I upped GH Bloom from 5 ml/gal to 7 ml/gal and added 0.5 g/gal Epsom salt, but that's the only change I made; as a test.

(plants in this post got ~39 ppm P)

Sure, but not right now. I'm hungry and got some watering to do. I'll post soon

For now, here is some info on citric aid you may find useful relative to this thread.This is info I have posted at ICmag before: "citric acid"

The chart is for all mediums, yes. It has been tested in ProMix HP, SunShine Mix #4, Coco/Perlite (currently being tested), and my custom soilless mixes with peat, aged pine bark fines, calcined DE, vermicompost, etc.

More later ...

 

[skyspider]

I use
FISH TANK WASTE ...FOR VEG AND BLOOM
FISH TANK WATER ...FOR SEEDLINGS
FISH MIX
FISH BLOOD AND BONEMEAL
ATAMI TERRAMAX BLOOM
BONEMEAL
VEGETABLE FEED
TOMATO FEED
BAT GUANO 'P'
I try to mix the soil first with blood n bone and bat guano ... the fish tank waste and water is added when needed as it is great stuff for getting all the complex micro organisms into the soil ... in the first week or so of 12/12 I do a top dressing with bonemeal , for 'phosphorus' and a half strength mix of bloom nutes ... I find the veg food is great for magnesium Def or Cal def etc

Nice looking profile spurr...

Are you boosting it at all?

What do you think of dropping micro at week 5 and doubling the Epsom?

Thanks. So far at least three people I know about have (and are currently) testing my mix either (or both) as 5 ml Micro/5 ml Grow/5 ml Bloom/5 ml CalMag+/2.5 ml ProTeKt or my current test mix of 5 ml Micro/5 ml Grow/7 ml Bloom/5 ml CalMag+/2.5 ml ProTeKt/0.5 gram Epsom salt.

Nope, not 'boosting' at all and yields as good as anything (and better than most due to inclusion of Si, and some closer to ideal ratios without excess (aka 'luxury') ppm(s)) and the smoke is always very tasty and odoriferous (I also do not 'flush' ... per se)

I for one prefer to use the mix as it is; due to various reasons such as the plants' ability to self-regulate (to a degree) uptake of some elements such as NO3 and P, etc. Dropping Micro is something I would advise against because it's a source of K and Ca; as well as N. If you wish to drop Micro to reduce N, I would suggest you try my current test mix, or my original mix, "as is" first. I have found not dropping N helps yield and plant health; as well as the (so far tenuous) scientific evidence that N levels are (possibly) positively correlated to THC levels.

Also, I try to include greater NH4 than many other mixes (ex. pH/Lucas mix, Greatfulheads mix(es), etc.), so I get a lower NO3:NH4 ratio, which can be important for plants that are grown with enriched Co2 levels. This is outside the scope of this thread, but there is strong scientific evidence plants can make much better use of Co2 when they are given more NH4 vs less NH4, esp. over weeks/months of growth under high Co2.

However, if you do choose to drop Micro and boost MgSO4 I would love to read about your results (I do think a little more S would be fine; so even if you didn't drop Micro, boosting MgSO4 could be worth a try)

where do you get this citric acid? about to run out of ph down....

 

[spurr]

Any beer brewing shop will carry it, only a couple of bucks for like 10 grams (or more). EarthJuice Ph Down is also citric acid, IIRC (but it's more expensive than buying from a beer brewing shop).

 

[spurr]

@ Kruch,

Do you use soilless media or some sort of water culture? (I ask because citric acid as the sole pH down seems to have greater flux in water culture than say normal pH down, ex., P-acid).

running rockwool right now.....
appreciate the info, you seem to know your stuff......
do you use much? with advanced ph down , 5 ml will drop a 50 gal a whole point....

one more thing, what do you think of running gh at 10ml micro and 15ml bloom only? its my current mix and it is seriously rocking...

[darthvapor]

krunch you can get citric acid at any meditteranean store for .99 cents for 4 grams. I use that to make a gallon. I got a bunch. I can give you some if you want to try. Btw your grows are badass, so simple yet genious.

spurr- going thru your threads now. Ive been making my own nutes now for a year. started off with fatmans threads. Lots of good info on there especially from toohighmf, that dude has tried everything on the planet. spurr Your what Ive always wanted to be a stoner scientist. Your posts are more like data.

You guys give me a standard to go by. You guys need a apprentice?? I got weed and whiskey!!
