I am auto-dosing EI ferts, and so a little over a month ago made up 1.5 litres of micro and macro mixes in separate containers using APFUK salts from their ‘starter kit’.
However the macro mix has changed from being completely clear to become very discoloured and has some ‘bits’ in the bottom of the container that could be some sort of precipitation:
I have another bottle of macro mix that I made up a month before this one, and that is still completely clear.
The only difference between them was the older mix used boiled and cooled tap water, and the newer discoloured mix used boiled and cooled DI water, plus has added ascorbic acid.
Should I be concerned about this macro mix, and it possibly affecting the availability of the nutrients it contains? If so I can remix some - though should I omit the ascorbic acid this time if that has caused the discolouration?
