Here's a simple question regarding fertilizers and dilution.
I have a bad habit of couring too much, so when I mix my fertilizer solutions I double up the water eg. so I can pour in 2x as much.
It's not really a cost issue, but I do use Flourish Iron and Flourish (acutally this bottle's almost out so I'll need to mix a new bottle of CSM)
Can I dilute my flourish iron with water? or is that a definently no-no that would ruin this mixture?
