And that is exactly my point...even without a so called "N" amendment one can still end up with very high nitrate that is certainly going to affect the plants health.
The crop will look fantastic, but it will be susceptible to pest and disease without the grower necessarily knowing it. Theoretically even with no N inputs if you overstimulate nitrogen fixing bacteria you can end up with high N.
I have gone 3 grows without adding a single N amendment, including compost, and my nitrate levels are still too high. Quite amazing what microbes are actually capable of.
