Discoloured macro mix . . .

Excuse me, being a stranger, what is 'APFUK salts'?

Aquatic Plant Foods UK ... a company here in the UK selling fertiliser compounds in sensible sizes, at sensible prices. Unlike a lot of the UK chemical suppliers

Hope you don’t mind me reviving this thread…
But I was wondering whether you resolved this issue? I have the same issue and I use rodi water with ascorbic acid and potassium sorbate.

Sorry @plantnoobdude I completely missed this post. Yes, as @Hufsa says, I just omitted the unnecessary ascorbic acid and have had no further discolouration of any macro solutions.

No worries, thanks for the response. I am remaking all my nutrient solutions, so I will be trying this.
