I only water to run off once every 4the watering to make sure the bottoms are staying damp. (Deep breath) soooo... what your saying is I probably have enough mag in there and probably enough sulfur also so when I add the gypsum that will add calcium and in turn will attach to the mag and sulfur that already,in educated theocracy, exists and supply's the plant? You lost me at Epsom salt on my crusty bag. Are you talking about the calcium attaching to...what salts exactly if I don't use bottled nutes salts from like say rabbit piss? ...and leeched out you mean flushed out the bottom? Which would in turn be a good thing. Apparently I'm not advanced as much as thee, respectably. I just got lost.


Sooo... let's just say this...guy I know... waters twice with epsom salt to correct a sulfur issue that was actually a calcium issue that was causing a sulfur issue and then said guy top dressed with 1lb of gypsum per 5 gallon container as directed on package and watered with ACT... do you suppose my friend would be on the right track? Thanks for your patience?? Lol so to much calcium may stop k uptake or at least appear that way?
Most likely Mag is locking out your K and not Calcium.
Watch this video esp around 4:00 a few times to understand how to lower Mag with gypsum.

Doing this with epsom salt will not work.

@Johnny-mariseed This kind of depends on the make up of your soil, the pH and whether you water to run off. The gypsum will dissolve and the calcium becomes freed up for the plant, while the sulfate (-- anion) will usually bond to another (++ ion) like magnesium and create epsom salt (magnesium sulfate) which will then leach and form crust on your bag. If you have high amounts of salts though, I think it would prefer to attach to sodium (++) and then can be leached out in the same way. If none are present, it could rob your Potassium however, but most soils have enough mag to not have to worry about this.
I topdress once the plant gets about a foot high and don't reapply.

I have finally given too much sulfur to my plant, but it only lasted until the plant got to about 24 inches and I saw no signs of the excess. (burned copper teeth on leaves margins that I thought was K)
So I just got around to watching this video due to bad cell service. The light finally clicked, after a week of bouncing back to this thread and finally watching this video. Thanks man this was just what I needed! I appreciate your help. I see you also are in the 207. I'm a Med. patient up in central.

You add lime for the total amount of mix, not just the peat. *I* prefer dolomite lime since it covers both cal/mag and pH buffering. Oyster shell flour isn't bad, just extremely expensive to ship. I've also seen people who mistakenly get chicken scratch oyster shell which is totally useless in a soil mix due to particle size.

useless yea, but I use it in every mix I have cuz it's puuuuurdy
i'm actually not kidding, I love that shit, it's super cheap and works as aeration too

I've had this excess sulfur issue before as well! Was a pain to diagnose I had to get a soil test to figure it out.
damn dude!
that's hard to do
I've used a LOT of langbeinite in my mixes and haven't seen that yet
course I think its a slow release sorta thing
but I love me some sulfur!

I wasnt even playing with Langbeinite yet! It was during an older run, I had made some mistakes with the mixing ratios. Amateur mistakes lol.

Annnnd, it just might help with pH buffering in 4 or 5 years time. LOL

Hmmmmmm ... Never considered it as aeration. Super cheap here also, just heavy as shit. Maybe I'll snag a bag when my kid is around to hump it for me.

I literally 100% use it just cuz it looks cool
I admit that's a lil weird, but it was an impulse buy years ago at the feed store
and ever since I just like the way it makes the soil sparkly
it actually does work well though, for the aeration anyways
