The best way is to dose TE when white new growth appears. Extra TE may be toxic to fish and plants. Fe is also a trace element.
This is absolutely the worst time to start dosing more iron. You should dose iron until you no longer see any improvement in your plants --not after the plants start showing signs of deficiency.

The extra traces that we add to our systems have to be dosed very heavily to have any negative effect from experience. I was dosing 20ml Flourish weekly into a 20g (76L) tank, and I had chocolate gouramis swimming around happily in this AND rock hard water (GH 14 or so). I believe water cleanliness is more important to fish health than worrying about too high levels of cobalt or manganese.
