MAX concentration before nute fall-out?

[RMCG]

Does anyone know at what concentration a two-part nute will start to fall out?

I am looking to build an auto-doser/fertigation unit that utilizes a single 5g bucket full of premixed (2 part) nutes.

IE 5g water and 200ml of A&B or can I get up to 500ml/1L?

I suppose I can start adding equal parts of the nutes in a 1 gallon jug until I see precipitate/fallout, just hoping someone knows off the top of their heads?

Not that it should matter much, but Dutchmaster Gold would be the line.

I know this isn't exactly what you are looking for but...The answer to this question is really dependent on the specific nutrients and each manufacturer (more specifically, each product line by said manufacturer) will be slightly different.

That being said, I believe at 200ml ea a&b you will be fine. 500ml of each may be pushing it with chemical nutes but should be just fine with organic based. We have done evaporation tests on res'es (never to 1/4 physical volume but close) and have not seen fallout beyond 12% with chemical nutes at roughly 1/5 volume.

Write DM and ask them what is minimum dilution ratio necessary to avoid precipitation. I am sure they will answer rather quickly, they seem to be very good at CS.
