does it replace just Flouish Trace or does it also replace Comprehensive? If it doesn't replace Comprehensive what am I dosing for that. I have run out of trace and iron. Soon I will be switched over to all dry ferts. yay!
Comp also has some NPK and some others, granted not much. Trace is just the micros I believe but has higher concentrations of them than comp. You can check what each has...
If you are going to switch over to dry ferts buy them all at the same time. Paying for shipping multiple times is going to kill most of the cost benefits of dry ferts
You don't need Flourish Trace at all. Look at what's in it and how much is in it. Heck, it isn't nothing but water. When you finish your bottle, you shouldn't buy any more.
Flourish (comprehensive) is what is comparable to CSM+B, but Flourish (comp) has more ingredients in it than CSM+B.
