The peat based container mix that I use and posted, has a ratio of 5 parts peat, 1 part chicken compost, 1 part perlite and has a tested value of over 600 ppm P, 250 Mg and 180 K with no other amendments. Thats what I was trying to say. If Im trying to make money, I run a peat/compost/perl @ 5/1/1 ratio...If I am working with soil and trying different techniques, I like to use my notill bed. It shows the downfalls of the LOS/no-till system high in EWC.
My chicken compost is stored under roof for 18 months. turned often when fresh, less once well composted. I put a fair amount of bone meal back into my piles.
I no longer use any type of vegetable waste directly in the piles. Everything passes through a chicken first. Helps with the Na and Mg.
No shit! I may never have a compost as time-tailored or well kept as that. I'm looking at lawn clippings and apple cores, if I'm lucky lol.
Before you sent in the Week 10 sample, how long had it been since you properly fed- either a PK boost or Flower base? Lets talk about that lower P number. Had it simply been spent by the plant at that point or is the test leaving something out that we can't see? Your feed should have that a tick higher, no? (available or not)
So in the week 10 soil you really do not want a "PK" boost. You want a soluble P boost. In every grow I see K can start to accumulate quickly in tissue the last 3 weeks or so. And the plant will start storing it in the bottom leaf...it does not need the boost...plus when they ash it for the test it will be blacker the more K it is holding. And excess is a pest/disease invitation just when the plant is at its most vulnerable anyways.
Based on that low NH4 number in the soil you could use some MAP or some TSP.
I do have soil tests for a few of the major cocos. IMO it is pretty useless for anything other than small pots fed hydroponically. All of them are the same...low Ca, high K and worst of all high Cl. Even the so called inland cocos have high Cl.
And if you load gypsum and don't use enough water to complete the cation exchanges you will cause lock outs from the Ca plus you have driven up another anion...SO4, which isn't as bad as Cl but it still competes with P.
It actually gets better over time but nobody reuses it. Makes you a little sick watching all of that carbon getting hauled to a landfill where you know a lot of it is gonna be volatilized into an atmosphere that damn sure don't need it.
Peat is a bit harder to use cause you gotta learn to buffer the natural acidity and you better understand the alkalinity of your water. Building decisions into big grows just makes the possibility of the occasional bad decision more likely
I find myself happier rocking a heavy soil LOS but it aint the future of big weed unless field grows get allowed...hemp though that is how I would go.
No feeds after week 6. I should have hit them with P. The plants that are vegging right now received a 125 soil ppm dose of P watered in after transplant...thats 250 PPA, no a solution number...Solution was probably 4-4500 ppm P...lol They loved it.
The EC has me not feeding like I normally would. This bed is a bitch to flush. No drain in that room.
That last run I gave them the last K at the end of week 5, after seeing the week 4 results. I anticipated buildup. The lower buds don't metabolize the k as quickly unless they are in direct sunlight. Another reason to harvest in succession...
NH4 generally comes from a small does of fresh chicken manure. I put a couple tablespoons at the base of each plant. Still working on that as I don't know the NH4 amount in the fresh poo.
What NH4 number do you like to see at start of flower?
I asked about the coco because I can't stand seeing the dumpster loads going to landfill...I can't believe nobody has set up something to take all that shit in...so much life left in it...
After this run, I am ditching the bed...going back to containers so I can flush them out...
Also wanted to make note... Day 8 plants vegging in the bed, No lockouts...no issues... Fed them with a base flower mix, 95-100-100-40-225. Hit them with a 250 PPA (125 ppm) dose of TSP that was dissolved in water and then watered in. Still need to get the MN up above 100. I will let them veg another week and flip. I think I will just run my flower base mix and a P boost this run. See how she does.
I only hit 2.2/1k last run, lower than usual.
Anybody want to straighten me out on the 13% K that Slowed called me out on? I can't come up with those numbers no matter how I do it, Even if I act like some of those elements don't exist. The only thing that comes close is Spectrums version where they disregard the excess calcium.
In a situation where the base is over saturated, I don't like to just assume the high Ca is magically no longer. Without leaching it is still in the container, still filling electrical charges. A balance of excess is still a balance when an exchange site needs replenished...is it not?
I have pulled samples here in Michigan with over saturated CEC base elements, is this not an occurrence elsewhere?
Hemp is what my plans are in the future for my farm. Unless legalization is a totally different system here, I don't want anything to do with it. A few miles from Lake Michigan coast...230+ sunny days a year...That big lake climate battery makes great late season finishes if the rains hold out.
Good to see you Led05! These last storms have been kicking my ass...hopefully you are fairing well.
Grown with it but not tested. Not impressed. Somehow the heaviest but least dense peat I've dealt with. Other brands I find can get me 14 five gallon pots but I could only get about nine out of the sunshine. Bizarre stuff.
Has anyone tested Sunshine #4?
