wondering if u have to or if u even can flush organic nutes.. like bone meal, considering thats what i am using..

You can flush some organic nutes but not bone meal. Bone meal is not water soluble and provides primarily phosphorus, which is not a mobile nutrient, so flushing has no effect on it. You should still flush your other ferts out though.

I have just searched for "soluble bone meal" and found about 3 diff threads wherein you point out that bone meal is not water soluble....but...prorganic ( I just ordered this ) has a liquid bone meal inwhich you are to dilute one ounce with water...this is what started my search in the first place

Is this liquified bone meal still going to take the 4-5 weeks to break down into absorbable nutrients???

Also;sidebar; is it bad to smoke weed that was harvested while the bone-meal"s phosphorous was in action???(since you stated it is unflushable)

Thanks for your answers

If the phosphorus in a liquefied bone meal product is water soluble, it means that it shouldn't need very much time to break down, if any. Anything water soluble is generally regarded as instantly available, the only question is if there is also some insoluble P contained in the product that would become available over time.

Check the NPK of this product. By law, listed NPK values of fertilizers indicate what is immediately available, not the total amount of a nutrient. For instance, rock phosphate is typically up to 30% P, but its NPK is listed as 0-3-0 because only 3% of it is available at any one time.

Also, I believe Brindie is mostly correct on this subject, but I do think that at least some of the available P in the soil should be able to be washed out, as it needs to become soluble (via break down) before it can be absorbed by the plant.

Left over nutrients in the plant aren't generally regarded as dangerous, but they can contribute off flavors and other generally undesirable effects.

Thanks, O. Can you explain why my dry bone meal says it's 0-12-0? It doesn't seem like it could have 12% immediately available P. How much does it have altogether?

I hadn't really thought about liquefied bone meal because I hadn't read much about it until the last few days.

organic

Y'know, that same question was bugging me as I was writing that, and I don't have any answers, only guesses. My guess is that maybe there is a relatively short time frame involved for the nute to become available.
