narnia Posted August 24, 2017 Share Posted August 24, 2017 Not sure if this has been around for a while, but quite a useful spreadsheet: https://hydroponic.co.za/detailed-dosage-breakdown-element-ppm-npk-ratio-hortimix-andor-ehg/ Quote Link to comment Share on other sites More sharing options...
Jimmy-z Posted August 28, 2017 Share Posted August 28, 2017 Would've been better if it included the EHG ripener. I'm using that for extra magnesium, phosphorous & potassium during flowering. As it is, I'm eyeballing the measurements for my first grow Quote Link to comment Share on other sites More sharing options...
narnia Posted August 28, 2017 Author Share Posted August 28, 2017 Jimmy-z[/member] Ya, agreed. They should plug all their stock in there. You should be able to just stick the ripener weights into the spreadsheet and mess with any needed formulas. I've been meaning to do so for the silica am using. Bit of a potassium bump there. (EHG Ripener)Contains: Phosphorus P 22,6g/kg Potassium K 38.5g/kg Magnesium Mg 14,9g/kg Quote Link to comment Share on other sites More sharing options...
alemo Posted August 28, 2017 Share Posted August 28, 2017 It must contain sulfur too. Surely... Quote Link to comment Share on other sites More sharing options...
narnia Posted August 29, 2017 Author Share Posted August 29, 2017 I would've thought so too, but not according to Horitshop site, neither any S in the Bloom formula, only the Grow. Anyone have a bottle of Ripener on hand? Quote Link to comment Share on other sites More sharing options...

narnia Posted August 29, 2017 Author Share Posted August 29, 2017 I'm using it now in my flowering stage. I have no clue what the effect will be. Lol (relative to bloom) No N - the major benefit, Small Mg boost, Slightly less K, - therefore slightly higher P ratio Can you confirm the labeling on the Ripener corresponds to what's listed on Hortishop (as posted in this thead) Neither Bloom nor Ripener contain any S, based on labeling, so none in feeding schedule from beginning week 3 onward.

Jimmy-z Posted August 29, 2017 Share Posted August 29, 2017 I can confirm there's no nitrogen or sulphur in ripener. Will get the amount of the components later when I'm home. I'm mixing all 4 for my feed. So they're getting a full complement of minerals Sent from my SM-N910C using Tapatalk Quote Link to comment Share on other sites More sharing options...
alemo Posted August 29, 2017 Share Posted August 29, 2017 So p,k and Mg. How does the mg get added??? MPK makes up the PK no problem, but the Mg? EDTA Mg? Quote Link to comment Share on other sites More sharing options...

Gnome Posted August 29, 2017 Share Posted August 29, 2017 So p,k and Mg. How does the mg get added??? MPK makes up the PK no problem, but the Mg? EDTA Mg? Magnesium carbonate probs? I'm thinking more magnesium sulphate Quote Link to comment Share on other sites More sharing options...
Jimmy-z Posted August 29, 2017 Share Posted August 29, 2017 So ripener is P 22.6g/kg K 38.5g/kg Mg 14.9g/kg. What I'm seeing is some type of salt coming out of solution if I mix all 4. But that's only if I let it stand for a day or two Sent from my SM-N910C using Tapatalk Quote Link to comment Share on other sites More sharing options...
alemo Posted August 30, 2017 Share Posted August 30, 2017 I don't think so, but I could be wrong. Wat is the pH of the stuff? Quote Link to comment Share on other sites More sharing options...
alemo Posted August 30, 2017 Share Posted August 30, 2017 So p,k and Mg. How does the mg get added??? MPK makes up the PK no problem, but the Mg? EDTA Mg? Magnesium carbonate probs? You mean chalk? I doubt it. Unless it is highly acidic. Quote Link to comment Share on other sites More sharing options...
Totemic Posted August 30, 2017 Share Posted August 30, 2017 If I were to add my Mag phosphate might be used here too. And would account for no sulpher. Definately not lime or gypsum. Quote Link to comment Share on other sites More sharing options...
narnia Posted August 30, 2017 Author Share Posted August 30, 2017 You mean chalk? I doubt it. Unless it is highly acidic. Lol ya, fair enough, chalk. What do you make of there being no source of sulphur from end week 2 with the EHG feeding schedule? GH Flora Bloom (which I thought EHG was loosely based off) contains sulphur and therefore fed all through flower, whether 3-part or Lucas. ....would it be stupid to wonder whether the S is left off the labeling of both the Ripener and Bloom?

alemo Posted August 30, 2017 Share Posted August 30, 2017 There almost has to be sulfur or something else. Else how would the Mg get mixed in? Most brands, GH included, use MgSO4. Quote Link to comment Share on other sites More sharing options...
narnia Posted August 30, 2017 Author Share Posted August 30, 2017 There almost has to be sulfur or something else. Else how would the Mg get mixed in? Most brands, GH included, use MgSO4. Ya, for sure. Magnesium sulphate or nitrate, as far as I'm aware. EHG Bloom *could* be explained as magnesium nitrate, Ripener obviously cannot given the major point is no N. Totemic[/member] kindly pointed out magnesium phosphate, just now which you may have missed as the thread stretched to pg 2 now. Ripener aside. With EHG Bloom / three part; it's pretty odd that a feeding schedule would contain no sulphur from beginning Week 3 of flower onward, isn't it? Logically I'd assume there'd be sulphur in the schedule, especially with hydro nutes. They list sulphur content on Grow labeling, why omit it from Bloom (or Ripener for that matter.) If not an omission from labeling, can one get by with no sulphur for that long? Quote Link to comment Share on other sites More sharing options...
alemo Posted August 30, 2017 Share Posted August 30, 2017 Which one? There are a few structures, none of which are soluble in water, only a solute, meaning the P needs to go somewhere? Quote Link to comment Share on other sites More sharing options...
narnia Posted September 6, 2017 Author Share Posted September 6, 2017 Update on this: EHG Bloom does contain sulphur @ approx. 12g/kg Quote Link to comment Share on other sites More sharing options...

narnia Posted September 6, 2017 Author Share Posted September 6, 2017 alemo[/member] Hortishop say they'll update the spreadsheet soon. Didn't query Ripener but presumably the same S to Mg ratio, or thereabouts, would make sense. Quote Link to comment Share on other sites More sharing options...
alemo Posted September 6, 2017 Share Posted September 6, 2017 Yes. Epsom salts. MgSO4. Magnesium Sulfate. Unless they use Mg chelate in Ripener, it will be the same. Quote Link to comment Share on other sites More sharing options...
