gypsum will most prob help with the N Clawing.. and sure extra sulfur will help boost resin production... i have only been using it in soil for a couple of weeks now and its great.. it kinda resets everything and brings it into balance... plants shine after about 2 weeks when it kicks in..

In what amount do you add it?I'll use some if I can find the time to go get it.

She got about 5 more weeks I think ,from which last two will be without feeding.

it will definitely bring out the magic.. id add it to all plants...but test on 2-3 first, then for your next round mix it in at 1 pound per cubic foot.. about 150gr for a 10L pot

Syd when you get the time, you should grab the Epsoma Gypsum and Lime Bags of them Pelletized.. ITs some of the best if not the best quality of those specific products, the price is also better then 99% of the other companies that sell those, and its the same amount.

I like the gypsum, one of the main reasons is because it doesnt have magnesium in it as well.. Everytime I found A product whether liquid or dried that was for calcium, it always had magnesium in it as well.. I personally ran into straight calcium deficiency issues, but then I used Cal&Mag and had Magnesium Toxicity.
That happened one time and was the 1st plant in that group to show the calcium deficiency. I had 2 more plants that needed calc but no mag, and I used the Gypsum on them but also topdresed with 1/4 dose of Oystershells.

Besides the crushed/lightly ground/powdered OysterShells. But Im pretty certain that it would take much longer to become available compared to the Gypsum pellets.

150 grams per 10 liter pot??



Me add one tea cup on 200 liter of soil and it get balanced and buffered,this your amount
looks like mighty overload.. there could be PH issues for plant if too much lime is inside
mix.

Also you "burn" your soil faster,there is a saying about Ca that "fathers" will celebrate but "sons" will suffer... and this saying is specifical for those that add too much lime,
its harder to revive this soils,they go dusty over course of a time,you need to use
more organic matter to made soil again proper bio active as this Calcium burns
more than you wish... its a death circle for soil life and organic matter..
 
Overload on the organics? Water plant well with pure water and let it be happy with some ph buffering. Wet-Dry-Water properly with pure water.

Hi friends. I try to deal with low feeding this week but plants isn't happy at all especially Larry King og but Amherst urkle dog respond good and like low e.c. I played with cal mag trying to help them but not much improvement. Dropped cal mag and start adding epsom nothing changed. Finally yesterday up basic nutes and plants perk and greener. Will see how they respond after few days. I prefer to keep e.c lower because I grow without run off but if plants want more what can I do?
Heres few pics from today.

Hey D,
im still new to gypsum and lime, like i mentioned,
but they are not the same thing!
what you are describing is about lime.. but gypsum is nearly the oposite
Gypsum does not change the PH!!

http://calciumproducts.com/component/k2/item/201-difference-between-lime-gypsum

Lime, or calcium carbonate (CaCO3), is the naturally occurring mineral used to improve an acid soil. When the soil pH is less than 7, acidity exists as an accumulation of hydrogen (H), and aluminum (Al). Aluminum, which is toxic to plant growth, is soluble when the soil pH is less 5.5. When hydrogen accumulates on the outside of a soil particle, or exchange site, their presence is measured by a pH test.

When lime is applied to an acid soil, the carbonate molecule (from lime) & hydrogen combine. The end products from this reaction are H2O (water) & CO2 (carbon dioxide). Calcium is now attached to the exchange site. Because the carbonate liberates the hydrogen, the soil pH will improve (become less acidic).

Gypsum, or calcium sulfate (CaSO4), is a naturally occurring mineral. It provides calcium & sulfur, both essential nutrients, but does not affect soil pH. It is a neutral salt (pH is ~6.7) & has a salt index, or osmotic potential, of 8. It typically has 20-22% calcium, & 16-18% sulfur. The sulfur is in a plant available, or sulfate (SO4) form. In addition to providing needed nutrients, the calcium in gypsum is soluble, even at a pH that is >7. This can be very helpful in improving soil tilth, reducing soil compaction, & improving aeration.

i picked this up in the Cec Thread, i might have made a wrong calculation, but they call for 1 lb per cubic foot..
1 cubic foot = 28 Liters
1 pound = 450g
~30L /3 = 10L
450g / 3 = 150g
10L=150g
correct me if im wrong..

anyhow im giving it a try and so far they are loving it

CaCO3 is what I use... makes a lil higher the pH, great for peat.

Ups.. you are right bro,i talked about agro-lime and you use
gypsum,its a different things,i agree..

Excuse me,was think everybody here use agro-lime for buffering.

Thanx for info,good to know this facts about gypsum... very
interesting indeed.


:tiphat:

no problem amigo...
as i say im still learning soil...
and you can teach me some things for sure...
i really like that you dont use aeration and 30% EWC..

i fucked up my first mix adding a fish meal that had some fungi..
it was a new box.. the lid wasnt closed 100%... it must have gotten wet some time in transit.. as it was one big block when i took it out of the 5L tub..anyway... i took only the bottom 1/3 as i thought there wont be any fungi in there, it looked normal...
wwwellll i was wrong big time... after letting my 600L mix sit for a week.. i saw white mycel growing, i thought ok.. prob Trichoderma from the coco..
i then potted my plants and after a few days the mycel was covering the surface of the soil...
at that point it dawned on me that it must be from the fish meal..
anyway to cut a long story short... i fucked up a ton of plants...
now after weeks of treatments they are starting to look better and growth is normal...
basically i made a perfect breeding ground for the mycel to spread in the 600L mix... lesson learned!

BRO... WTF :whee:

Killer!

39 days... she is going to yield big time by the looks of it.

Thanks so much T!, means a lot coming from someone like yourself...

Yeah I hope so!, she's hooked up to a hydro halo a long with the Amherst Urkle Dog getting fed 4 x a day.
