I have done some testing in this area due to the wide range of opinions about the topic. I asked people who I purchased plants from as it seemed to me that if they were good enough at growing plants to sell them, they must know something. I also tried various levels of FE over a couple of months.
My own results found that .5PPM is best for me. In my tank FE is the limiting factor for growth as I have many fast growing plants such as glosso, riccia, and hydrocotyles. I also found that if I overdose FE the only problem is that staghorn algae starts to appear. This is remedied by ceasing iron for a week and then dosing at a lower level.
Note: Results may vary depending on the type of plants you have.
hope this helps

Having done some research on iron I have a question. The general recommendation is to maintain your iron levels at 0.1 mg/L.
Is this chelated iron or free iron?
The conclusions that I have made based on my reading is that I should be testing for free iron and that I want to make sure that I am getting a colour change indicating that there is iron present and that I shouldn't let it get too much over 0.1 mg/L.
Does this sound like a reasonable way to go?
