Where is the K in the super soil? i see none! why is this?

A K deficiency would show itself fairly easily. lower leaves scorch like a torch was put to them. I must say Subs recipe is so well balanced, in side by side comparisons Subs soil is still rocking with no nutes and i transplanted in april. My other organic mix with chicken manure Has started to fade and show actual def. Now im feeding those with the whole earth juice line. PITA! SUB you rock.

I read someone else make that very same good point. With all of the very particular growers liking the super soil, clearly there's no underestimation of K sources. Or people would have been bitching years ago.

I dont think Kelp would hurt BTW just dont go over board like stated above if the recipe wasn't balanced people would hand me my ass in a hat.

Potassium in Sub's super soil comes overwhelmingly from worm castings. I'm skeptical that the potassium in coco coir is available quick enough or in high enough concentration to provide the plant with all it needs. That's a LOT of lignin and cellulose that needs to breakdown first to make K available. I have no doubt it plays a role, but, like rock phosphate, I don't believe it is bioavailable enough to be an ample nutrient source for short-term container gardening.

Just a thought sub if you want to silence all the nay-sayers , you could get the soil professionally tested.

If I were SubCool, I wouldn't give a shit about the nay-sayers. He's not selling SuperSoil. It was a gift to all of us.

I am digging this answer. I Googled K levels of worm castings, and sure enough, depending on how much high K mulch was in the worm bin (fuit, etc) the K levels of EWC (Earth Worm Castings) can be quite high. Thank you hb rob.

I couldnt get any roots soil so I used something similar and added coco. The rest of the recipe i followed to the T and WOW its def some great soil.

One treatment of Azamax took care of the fungus prob.

My answer to the debate on K is it must be in there you guys have seen my plants and there are no deficiencies that I can see.

I will try some Maxi Crop on the Cheese to see if thats why shes such a bitch in flower but what she does in super soil she does in AN hydro and ever other medium I have seen.

Last years Space Bomb cover of Hightimes yielded 9 ounces theres no way the soil is lacking.

Last years space bomb, Was this a outdoor plant or indoor?
sorry for the stupid question. Just curious.

Outdoor plants yield pounds not ounces silly.

I have some 40 and Back to Back indoors grows with this recipe best meds I have ever grown you guys can debate this or use it or not use it I dont really care. I was trying to share something that works with the world not have a 4 year discussion about every ingredient.

I just want to say since the first time I tried super soil I haven't looked back. It's the easiest way to get superior quality herb consistently without any fuss and I want to thank Sub for giving out the recipe.

It would help so that you don't have to have this argument every 4 years, but hey, do your thang playboy.

if you are willing to follow subs recipe,and let i cool.you will have the best most simple grow ever.ive been using for years .first one then the revised one,subs the man .i had my problems when i didnt let it cool,but then,heaven.ive crossed subs conquistodor with flav,the greatest ever.sub is on top of his shit''''''''''''''''''

I'm starting a SS grow with Plushberry. I'm excited.

Just another vote for the readily available K in the EWC castings of the SS recipe. The SS seems very balanced and has such a long track record on this and other forums I'm not sure why it's even debated all these years later.

For some strains, Roots Organic alone has enough nutes to carry through flowering and have a decent yield. For hungry girls, yields are hugely improved by adding amendments.

The K issue in super soil may relate to the high P myth. Some growers believe that we are using an NPK ratio too high in P and as far as I can tell from experimenting it appears to be true. High levels of P are useful outdoors because P is easily leached out. Indoor organic grows do not need runoff every watering so the extra P is unnecessary. Adding P to Roots Organic soil may increase your yields to a point, but to improve your fertilizing efficiency and ultimately achieve the very highest yields we may have to reduce the ratio of P and increase the N and K. In that case K becomes the most abundant nutrient during flowering.

Organic blackstrap molasses is a great source of K and as Sub mentioned Kelp Meal is also.

If the microlife is active, the amendments will be more available to the plant. So to your good point, Supra, this would increase your fertilizer efficiency.

No it wouldn't. It would just mean he'd have to dig out the report every four years. Don't be obtuse.

It's hard to say definitively, so many variables involved. No one answer works for all. Try testing your soil, each will have slightly different results.
