Liquid Fluid Chemical compound Service Health care

Multi-micro combi from multinational fert company Haifa.
Iron 7.5%
Manganese 3.3%
Boron 1.3%
Zinc 1.3%
Copper 0.3%
Molybdenum 0.2%
EDTA chelate for Cu, Fe, Mn, Zn.

Haifa website gives different percentages so I think our retailer adds some stuff by themselves (or lie)
What Haifa claims this product to be:
7.1% Fe, 3.48% Mn, 1.02% Zn, 0.76% Cu,
All as EDTA chelates
0.485% Mo as ammonium molybdate.

They don't sell CSM+B where I live and this is what people use to make their own trace ferts.
It works well with most plants, but I did have problems with some sensitive plants like macrandra.
For macrandra I had to go very low like 0.005ppm Fe....or below. (To be honest, not dosing traces had exactly the same results. I do use aquasoil.)
As far as I know this is common issue with generic chelated trace mixes on Lythranceae no?

Anyways would be fun to hear what all those fertilization pervs think
For now I am trying out un-chelated micros with gluconate and citrate and fulvic acid and all those wierdo stuffs.
