my mind tells me that the plants should (and do) show me what they need and if they are happy, or not ... i'll go back to lurking ..peace

The idea is that by the time you see what a plant needs it’s too late... I don’t entirely subscribe to this though as I believe everyone sees things at different points, a deficiency to me or you could show days or weeks apart etc...

Generally speaking though, when you notice something off, you’ve left some on the table

Don’t lurk, add, everyone here adds value

she's a tuff plant for sure ... you would be surprised how badly i've f*cked up in the past with nutrition and still sort of pulled it off in the end...I understand what Ur saying btw ...dont wait till it's too late ...

Azomite

Slow

Throughout this thread I've heard your distaste for Azomite, I get the ridiculously high content of Al but when mixed at such small amounts I'm curious its effects, especially on the scale it's used commercially - herd mentality...?

Do you have testing for this or is it just simply, holly crap, 11% Al, wtf, stay away... ?

I got a 50# bag sitting here, I add it to new beds at a rate of a 1 # / 10 SF and never seen an issue but have never used it in pots, inside or in GH so its' difficult to measure true effects

Thanks

You're OK with adding Molybdenum, but scared of sodium?

You stand a much higher chance of killing things by overdosing the molybdenum than you would from the sodium that comes along with it.

I wonder how many people in this thread have a water softener my guess more than who realize...

does filtration prefer Mg, Ca, K or Na....... read up

If anything molybdenum additives would be helpful specifically for soil health, not more so for plant health.
Where did you see the 1000 ppm toxicity number? That's not accurate. At a thousand parts per million you to have more molybdenum than potassium in a lot of soils and molybdenum is considered a trace mineral, not a macro. I have molybdenum in my greenhouses at about 4 to 5 ppm and I consider that luxury levels. 2 ppm is probably sufficient for most. To get to 4 to 5 PPM it takes very little sodium molybdate to get there so the amount of sodium that comes along with it is negligible.

I think you must have read it wrong. You'll be hard pressed to find any knowledgeable people that wouldn't say you'd be risking toxicity above 5 ppm. The University of Wisconsin, Oxford, Oregon State Ag Dept, Agricultural Canadian Research Station, Graime Said, etc. all say 5 ppm is about the healthy limit in soil. Spectrum Analytics says 1 ppm is sufficient for most crops and most of the rest say around 0.5-2ppm is sufficient for most crops.

And just FYI, you could use ammonium molybdate or molybdenum trioxide also, but I don't know how cheap or easy to find those are. Sodium molybdate is cheap and easy to find.
