For example, I keep about 20ppm nitrate and 2ppm phosphate in my tank and have never had algae growth, but I'm sure if I turned off my CO2 then my tank would be a disaster. I could be wrong through. Anyway, my point is that whether you choose to use CO2 or not, you'll need to setup and operate your tank accordingly.
Once a week flourish comprehensive... if I remember, 2 root tabs for my valls and swords. 14 hours light (I know, it's just the way the schedule goes at home... we like to see the fish in the evening)
0 nitrates, I'm pretty sure that the plants are sucking up what does appear as I did have some a little while ago. I don't check for phosphates so they are minimal I am sure.
You are correct , additional nutrients without CO2 and more intense light would be a disaster, it has to be balanced based on the method that you are using. If I bumped up my lighting, added CO2 and started dosing other stuff... I wouldn't be able to keep ahead of my stems. As it is I'm cutting them in half every week and often see 1" of growth in a day.
I chalk it up to a steady ammonia load in the water. I saw the plants shoot after adding 9 new fish and ammonia levels hovering at what I call "non-zero" levels... nowhere near 0.25ppm but not quite zero.
