Epsom Salt and Sulfur Supplements

[Eledin]

Epsom salts has always been a terpene hack here... (I've recently slowed down on that idea) I saw it on a Mr Grow it podcast with Brandon that some phenos have either a positive reaction or a negative.. so your milers may vary? Also to much Magnesium can block Potassium... so another thing to think about.

Basically too much of one thing can fuck up any other nutrient yes, its just a matter of watching how the plant reacts and acting fast when you see the first symptoms in my case. Epsom salts are also great at dissolving accumulated salts if youre using mineral fertilizers. Flawless finish from AN is basically magnessium and sulfur at the same ratio than epsom salts so... pink epsom salts with water! Hahaha. It will also increase nutrient absorption thats why I dont recommend using epsom salts when youre loading a lot of nutes, you can burn them, I usually add epsom salts when I use only water.

 

[Eledin]

My last assumption is also backed by the fact that AN warns you not to mix flawless finish with nutrients, which makes sense if what I read is right. Its suposed to dissolve salts into available nutrients again and increase absorption so the plant cleans the plate (pot) basically.

For DIY lactobacillus there's plenty of tutorials in youtube. Its really easy you only need rice, milk and water.

For water soluble calcium without resorting to comercial calmags which might result in nitrogen toxicity since theyre all high in nitrogen, I have a guide here. Its cal-mag-sulfur:

Fast absorption calcium from egg shells.

I wanted to post an update. You can do the same with dolomite lime which also contains magnessium if you dont wanna use eggshells and epsom salts. Or if you have some dolomite but no fast absorption calcium. Or if the plants are showing signs of N toxicity and you dont wanna use a calmag. The...

Fermented plant juice well... pretty straight forward hahaha you just need to google which plants are best fermented for weed. You can use your previous grow stems and leaves but you cant abuse it or you will saturate the soil with chlorophyl degradation byproducts (or at least Ive been told that, never tried to go an entire grow with just fermented plant juice).

@Natep I have a question if you dont mind, what should be the ratio of calcium to phopshorus for optimal intake? I use bat guano, I think I put enough, but maybe I could use a bit more.

I have no idea. I use my wsc at 1000:1 ratio same with my wscap. To make wscap cook bones till they turn black and flaky. Then desolve in vinegar.

i got some calcium sulfate for late flower to lower N with masterblend formula.but i havent tested it yet.it desolves really slow in water soo i dont know how good its gonna be but it should be a sulfur bomb with epson :D

I use carbonaria from New Millennium, and it’s a ferment of lots of different plants, but it works really great whatever plants are in it ha ha ha.

It’s so pulpy

If you want less nitrogen and more Sulfur. Why not reduce the Calcium Nitrate, and use more Epsom Salts?

Also might look into Langbeienite -0-0-20. Its high in Sulfur-Magnesium, and Potassium.

well didnt i just write that? okej soo masterblend is a 3 part nute.base nute has all the micro shit and small amount of n and p or k i forgot.
then you have epson salt aka magnesium sulfate and then you have calcium nitrate he gives you 80% or 90% off all nitrate the nute has. insted of him i get calcium sulfate plant gets her calcium but loses huge amount of nitrogen.

only problem is it can take days for it to melt in water. not a problem if you prepare your water few days before i hope.all what i have tested soo far is that it does drop around 20% in the first hour.now is that because the water got saturated or they are not melting fast enough no idea.

i cant remember if i tried low calcium but i think she wants to eat the dose she has now.

The increase on smell youre noticing is not terpene related but rather a sulfuric compound that weed has similar to one found in skunk spray that gives it that funky, skunky smell. Its not a terpene but it certainly increases flavor and stank!

No. Weed smells like carboxylic acids. Sulfur does nothing. Who told you this? The amount of S needed for thiols is absolutely miniscule. Every fert on the market has plenty from cheap trace mineral sulfates. Thiols get their S from Cysteine, exclusively. Which is a protein synthesized from nitrogen. So the point is moot, when pot growers pay zero attention to protein metabolism or transcription factors.

All your weed forum theories are nothing more than people mocking you and wrecking your weed. I hope you know that. I hope you know grow forums were the worst thing to ever happen to weed.

\/ How amazing do you imagine this weed was? \/

My client says he threw it in a dumpster, so I imagine it was pretty bad when he came to me for help, after the internet forums ruined his crop with literal sabotage. This is what happens when you listen to gurus and dump on a bunch of potassium sulfate "for da terps". Your weed goes in the trash and now your soil is overloaded with sulfur and makes mineral balancing a nightmare for 99.99% of crop consultants.

I’m looking forward to seeing the results I hear sulfur will dramatically increase your skunk factor.

Tell us who spreads this nonsense so we can stop listening to their lying ass and kick them off whatever stage they've glued themself to.

Magnesium to Manganese ratio determine malevonic vs methyl erithritol 4 phosphate pathway activity. In the fake pot expert lingo that would be "Manganese for monoterps, Magnesium for medicinal terps" yet no fake pot experts can seem to get that out.

3-methyl-2-butene-1-thiol is not a terpene who said anything about it being a terpene?. You need to update yourself mr "forums are way below me but Im still here". Studies from 2023 and 2024 have identified 3-methyl-2-butene-1-thiol as a major aromatic in weed, specially in tropical like strains.
You wanna get sciency? Okay lets go, I get my information from google scholar so we can exchange plenty of studies. Lets start with your 3-methyl-2-butene-1-thiol comes from cysteine hence adding sulfur is useless, thats wrong:

Abstract​

In plants, cysteine biosynthesis plays a central role in fixing inorganic sulfur from the environment and provides the only metabolic sulfide donor for the generation of methionine, glutathione, phytochelatins, iron-sulfur clusters, vitamin cofactors, and multiple secondary metabolites. O-Acetylserine sulfhydrylase (OASS) catalyzes the final step of cysteine biosynthesis, the pyridoxal 5'-phosphate (PLP)-dependent conversion of O-acetylserine into cysteine. Here we describe the 2.2 A resolution crystal structure of OASS from Arabidopsis thaliana (AtOASS) and the 2.7 A resolution structure of the AtOASS K46A mutant with PLP and methionine covalently linked as an external aldimine in the active site. Although the plant and bacterial OASS share a conserved set of amino acids for PLP binding, the structure of AtOASS reveals a difference from the bacterial enzyme in the positioning of an active site loop formed by residues 74-78 when methionine is bound. Site-directed mutagenesis, kinetic analysis, and ligand binding titrations probed the functional roles of active site residues. These experiments indicate that Asn(77) and Gln(147) are key amino acids for O-acetylserine binding and that Thr(74) and Ser(75) are involved in sulfur incorporation into cysteine. In addition, examination of the AtOASS structure and nearly 300 plant and bacterial OASS sequences suggest that the highly conserved beta8A-beta9A surface loop may be important for interaction with serine acetyltransferase, the other enzyme in cysteine biosynthesis. Initial protein-protein interaction experiments using AtOASS mutants targeted to this loop support this hypothesis.

Second of all, being condescending to everyone in the forum who tries to share knowledge, be it wrong or not, is not gonna get you far so I suggest you get off your high horse and stop calling people names because you think you know a lot more, which might be true but ever heard of staying humble? We all had limited knowledge and gave mediocre advice at some point based purely on flawed observation due to lack of studies in the past. So you dont like bat guano during flower I assume? What a same. Also nobody said that saturating your soil with sulfur will help, but the extra sulfur from epsom salts does help along with the magnessium to assimilate the remaining nutrients faster. Maybe it is new to you but thats the reason why so many commercial growers flush with espsom salts. Lets see whats in the formula flaweless finish from AN which improves the final flavor... hmmm wow its sulfur and magnessium, oddly at the same rate as epsom salts... is as if they are selling you a flush and aroma enhancer which is basically liquid pink epsom salts! But hey I bet you know more than brands too. You do do Ill stick to my updated studies.

 

[Eledin]

I wonder why sulfur deficiency during the last stages is so prevalent if you dont add enough too towards the end... can you explain that for us with something else than your word? Is probably the most common deficiency alongside mineral deficiendies due to high ph. We dont need more sulfur at all right? There's plenty and you say that with a straight face without even going into detail about the soil. Is it ammended for transplants? Is it a light to start from seed?

 

[Eledin]

Also sulphur plays a major role in protein production aswell as aminoacids, enzymes and vitamins. You wanna talk about protein metabolism whie saying sulfur does nothing? Well not without sulfur. Also duh, again, too much of ANYTHING is bad, I think you dont need to be Einstein to know that and I think nobody here told anyone to buy potassium sulfate right? We are talking about epsom salts towards the end of the cycle... and who told you I use synthetic fertilizers? My sulfur comes from bat guano mostly and them some with epsom salts towards the end.
And no, 100% I can assure you that the soil I buy doesnt have NEARLY enough phosphorus (or any major nutrient for that matter) to get from start to finish because I buy light soil and ammend it myself.

 

[Eledin]

Also now that Im ranting (sorry op I took this personal as I dont like people coming trashing everyone). You cannot create sulfuric compounds without sulfur, and guess what, if the sulfur in your soil is depleted you can add all the nitrogen you want, no sulfates without sulfur, basic chemistry right there.
EDIT: Sorry for the non involved people, Im pretty chill most of the times trust me hahaha

 

[Eledin]

Forgive my mind fuckery as Im a ittle bit too high, I think I might have used phosphorus when I meant sulfur and probably also viceversa. Hopefully you can still get the idea because Im not reading all that again and I cant edit it hahaha. Bat guano is rich in phosphorus and sulfur, aswell as other minerals if I confused anyone with that, I think its my main source of sulfur but not the only one, worm castings have too. Also forgive my typos, english is my third language and when Im writing fast it shows.

What bat guano for flower? Mine is 7-3-1 is that to much nitrogen? Also what about seabird guano?

Your bat guano is probably mixed with seabird guano, check the label. My pure bat guano has 10% phosphorus, 1% nitrogen and 0,1% potassium. Usually when bat guano has more nitrogen than phosphorus is because its not pure bat guano. Seabird guano I dont use because for NPK I have alfalfa meal, kelp meal and neem meal.
I would say that your guano has indeed too much nitrogen for flower, I always reduce nitrogen after third week of flower.
My top dressing PK booster for mid to late flower is basically bat guano (phosphorus) with palm tree ash (potassium)

He is literally the guy who goes to a party to complain about how much he hates parties
Im pretty sure that some bad advice has ruined weed but whenever Im told something I dont know I fact check it. I think it should be common sense to not trust strangers just because theyre in a weed forum. Its so easy to fact check with google instead of fucking your plants...

Lowest N bat guano is happy frog cavern culture at 1-12-0. Where do you source your gua o from?
