Can you suggest a specific product? My lfs won't carry anything other than excel or the micronutrients - they say it's unsafe to dose macronutrients to a tank that houses fish (I know that's bullocks, as many do it, but it does make me nervous that the lfs has that position - how easy is it to overdose and kill my fish?). If I start using nitrates etc., I'll likely need to order online.

I don't see plants dying when I move them from one set of conditions to another. They just sit there doing nothing for a couple of weeks or longer. Sometimes some of the older leaves fall off, but I can't recall a plant just dying.
Most "aquatic gardeners" dose nitrates and phosphates - probably all successful ones do. And, we all keep fish in our tanks. Tom has demonstrated that you can increase the concentrations of each nutrient well beyond what is possible to reach when using EI fertilizing, and it doesn't harm the plants or the fish. The worries about nitrates and other fertilizers in fish tanks all come from fish only tanks, where there is nothing there to consume those substances. That is why the LFS sales people tell folks what they do.
Another source for fertilizers on line is:
Rex's ferts. The only substances you really need are KNO3 for nitrate and potassium, and KH2PO4 for phosphate. If you don't allready have a trace element mix, which you do have, CSM+B is an adequate one in powder form.
