Ok, so let me restate. Too much N and K for that amount of light and enviroment. At a greater rate of transpiration and photosynthesis, those amounts of N and K might be necessary, even not enough maybe. But under these circumstances, if you are unable to increase rates photosynthesis and transpiration, then lower your N and K, because the plant is exesively storing nutrients and not metabolising them.

Excellent point. How do you lower the K? The soup is already made.

exactly, very nicely put

calsil raises pH. in this case i would rrecommend gypsum. i agree with you from time to time.

gotta watch washing out mg to...but that is way easier to fix than too much k salt in the soup.

ultimately i would say fuck bagged soil. make your own based on what is locally available

Actually, pretty sure it is easier to wash out K than it is Mg. Mg is a bitch to get rid of.

Yeah, I noticed that you agree from time to time. Me too! Impressive!

Yea, I'd water to runoff with calcium sulfate (and maybe milk) along with some citric acid, fulvic acid, sugar, and trace; mainly Mn, B, and Mo.

That is probably why I had a touch of K deficiencies near the end after flushing my bad mix to make it livable ha.

The gypsum flush worked much better than plain tap, EC flew down much faster... Bagged mix I'll never do again, maxed out my EC meter fresh out the bag ha.

So here is a question, what can we use besides coco or peat for our mixes?
Adding peat helped with my texture but it was 1.1 EC out of the bag or something like that. The shitload of calcium affected my texture in a good way and improved drainage as the soil particles grouped up into larger pieces but is there a better alternative than peat or coco for mixes?

This is the start of a great series of lectures I suggest everyone here spend the 30+ hours listening to every one - he starts getting into CEC and AEC in soils around lecture 16 and it gets better from there, but you really want the stuff before that is more boring as a base to go by.... Lots of good info about humic and fulvic substances, and what they are and do... But imo watching the Harley Smith classes you'll get all the useful info you want from these lectures in much much less time, especially about fulvic/humic and how to actually use them to benefit your plants.

So many other good lectures available on youtube that are very underwatched.. OOooh look! Cat video has 5 million views SO cute mew!

Call local landscape companies or top soil/fill/rock suppliers and look for a good loamy top soil to start with. Get it tested for mineral content and pesticide and glyphosate residue. Add some aeration and OM, and balance the minerals.

Good question Tony. Let's get the group to participate. They all have much more experience than I in these hybrid mixes.

The peat and coco just tend to make things pretty idiot proof.

As I mentioned previously, I would suggest a CEC of 12 to 15 or so. Lots of airspace. Limestone rock or a good stone would be good. Jidoka say he can make a mix that eats rocks. I wouldn't doubt it. Once this plants goes into turbo root mode, the quantity of roots is amazing. All emitting oodles of organic acids, sugars etc.. Personally, I use half to one inch limestone rock in my couple of plants, peat, rice hulls, WC, compost, triple super phos, biochar from rice hulls and left over soil samples that are real sandy...

I have heard that Oregons Only Nectar of the Gods has a good soil mix, full of calcium. Those guys know the importance of calcium, not sure about their nutritional strategies and their woowoo juice, but they sure know what makes for roots and healthy plants.

Random thought...I recall reading somewhere that most commercial bagged soils purposely keep Calcium around 40% or less. They do this because if these light mixes had high calcium, sitting in bags, on pallets, getting shaken and trucked around the world, the calcium tends to stratify in layers, and this is aesthetically negative to the consumer.

Plan on it, gonna get soil tests before I run anything again and see what its lookin like.
