I found Brightwell Florin Axis contains-Kelp, Fulvic acid, Humic acid, Magnesium sufltate, hydrolysate
When I run out of iron fert I will be trying it.
I have used Excel with Vals just dose 1/2 of normal dosage.
I another item I am experimenting with to decrease use of Excell is Hydro Peroxide. I will posting results under Hydro Peroxide experiment in a month, if it works.
