Thanks for the input my friend, but that's not what I asked at all. I think you missed the part where I wrote I finish the plants with full strength Masterblend, which is the same as you. You just told me how to make stock solutions. I'm a little passed that working with salts, making my own nutrient blends specifically for coco. I use more cal nit in a single rez, than your stock solution contains.I've used master blend 3 parts for a long time, it does do a good job if you mix it right, give the base and Epsom salts enough time to dilute before adding calcium nitrate. A lot of times I would get some sediment in the bottom of my buckets which means some of the nutrients were falling out. For me the best way to use it is take 3 1 gallon jugs and make a strong solution up. You will have three jugs
A- for base.
B- for Epsom salts
C- for calcium nitrate.
After doing it that way my reservoir stays crystal clear with no sediment at the bottom. I would mix 120 grams of Base to jug A
Would add 60 grams of Epsom salt for jug B
And add 120 grams of calcium nitrate
For jug C.
So if you wanted to mix up a 5 gallon bucket at full strength of master blend you would just add 360 ppm for jug A
And add 115 ppm from jug B
And last add 360 ppm of jug C
For a total of 835 ppm using RO water and you don't get any sediment in bottom of bucket stays crystal clear and there is no fallout from nutrients.
Do you have any input about my initial post? I don't think your understanding the point of this thread. Especially while giving advice on masterblend with that pic of that over fertilized plant you posted.If you want to stick with master blend 3 parts, you know you cut back on the calcium nitrate, and up the magnesium with epsom salts, and people use flower fuel in the flowering stage. You might want to look into it.
That's an awesome link! Thanks for that. However, this study was in DWC and not coco. Shouldn't their optimal numbers be different then? If potassium doesn't significantly affect yield, it might affect potency and terp content.Potassium is not an element that significantly affects yield in cannabis. It's definitely not a bloom booster. This is science not an opinion.

Then why do nutrient companies make coco specific nutrients that contain less potassium, to make up for the potassium it gives off as it decomposes??Coco doesn't contain a significant amount of nutrients. Especially not potassium.
No, it DOES matter to me. And if you were paying attention to my initial post, you'd understand I'm making my own blend of nutrients from salts.Because nutrient companies often mislead consumers in order to sell their products. You should ask your nutrient company how much K coco "gives off" as it "decomposes". Then ask them to provide proof to back up this dubious claim. If you were paying attention to the study I posted, you would know that the amount of K provided to the plant can vary quite a bit while getting the same result. Doesn't matter if its hydo or coco. So you are worrying about something that doesn't matter.
Could you cite a few examples where bottled nutes have a higher (than unusual) K and the manufacturer explicitly states this is due to decomposing cocos?No, it DOES matter to me. And if you were paying attention to my initial post, you'd understand I'm making my own blend of nutrients from salts.
So basically your saying all the coco growers are getting the correct nutrient profile with coco specific nutrients? And everybody else is getting ripped off by the nutrient manufacturers because there is more potassium in the nutrients? Highly unlikely or the manufacturer would cut costs and make ALL nutrients with lower potassium if that were the case.
