What's your reccommendations LeighMo - w.r.t. which type of dosing is best ?

I've never tried Flourish Nitrogen, but I'm curious about it. (They claim
"Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources.
It provides nitrogen in both the nitrate form and the plant-preferred ammonium
form. However, no free ammonia is released because the ammonium in Flourish
Nitrogen™ is complexed and unavailable until utilized by the plants. Flourish
Nitrogen™ also provides nitrate for those plants that can readily utilize
nitrate as well." Probably just marketing B.S., but I want to try it anyway.
:-)

Right now, I use plain old potassium nitrate, bought from a chemical supply
house. Being too lazy to mix up a solution, I use the Tom Barr method: I just
dump the dry powder into the tank, a quarter teaspoon at a time. I also use
Jobe's spikes and root tabs that contain nitrate.
