Hi guys, I know flourish is a more complete fert, but the price is way more expensive. Plus its so low on iron you would have to add the flourish iron to cover. I was wondering if anyone has used the flourish and the combined with the CSM-b mainly for the iron? I found the 2l flourish bottles for 20 bucks, so I am going to try it and mix it with the CSM-b, i just want to know the mix %.
