Cloudy Macro from EI salts

[Simon Cole]

I've just mixed up my last batch of macro using the same old EI salts and deionized water. The mixture has turned rather turbid, usually it goes clear.
Is this something I should worry about before dosing? Will it still work as fertilizer? Has it knocked out anything? Do I need to change the order that I mix the salts together?

Hi all,

The mixture has turned rather turbid, usually it goes clear.

You could try warming it, or diluting it with more DI water, if it goes clear you've exceeded the solubility limit of the solution.

You can think of it like continually adding sugar to a cup of tea, eventually some will remain undissolved. If you started with tea made with salt water (strange I know, but bear with me) you would be able to add less sugar before the same thing happens.

Which salt is undissolved (and unavailable) would depend upon their solubilities and the common ion effect.
