I would definitely suggest extra FE. To avoid algae spikes add FE slowly adding more each week. Then hold your dosing level when your plants get the desired color you want. If you just dump in a random amount you'll get GSA growing out of your orifices.
It's not necessary with enough trace dosing but my plants personally become rather pallid without strong FE dosing. I just make my own stock solution at the same concentration as seachem's iron formula then dose to their directions.
