What Is Unsafe For Nitrate?

[Dave Spencer]

Your plants are probably using the fertilisers nutrients and therefore not needing to use as much nitrate. Thus leading to the slight build up you noticed.

This doesn`t make sense, as the ferts are nitrates too.

Plants use more than just nitrates to grow.

For all we know, her light could have diminished in recent weeks causing a loss of efficiency in photosynthesis.

yes they use about 20 nutrients!!!, but if one is missing then it leads to poor plant health, especially considering Nitrate is a macro and needed in higher quanties than micro's (trace elements)

I doubt lights would diminish that quickly, and even still efficiency wouldnt lower, just the rate of photosynthesis. The only time a decrease in photosynthesis efficiency occurs is when there isnt enough nutrients.

I am getting the impression that it is not something I should worry about too much, but what do you think might have caused the spike if not the fertilizer? My Nitrate was at 5 or below for weeks then jumped to 50-60 days after adding the fertilizer and that is the only thing that I had done differently.

I am not sure to be honest. If we take a look at the most popular fertilisers, seachem nitrogen, easy life nitro & Tropica Plant nutrition+
each one adds 2.5ppm, 2ppm and 5.9ppm respectively. Even when dosing Estimative Index which adds the most amount of nutrients is 5-10ppm per day.

Are you sure you have read the instructions correctly?

Perhaps you should post up the nutrient content amounts/percentages of the Ancient Amber here from the fine print on the bottle. I've never heard of the stuff (not saying much since I'm usually more irritated with what the LFS shelves -don't- have than what the colorful bottles are that the -do- have )

Pulling one of my various Flourish bottles from the refrigerator next to me here, there's a "guaranteed analysis" chart that breaks a dose of the fertilizer down into x percentage of many of the various elements (N, Fe, B, etc.) and simple compounds (soluble potash (K2O), Phosphate, etc.) that one expects to find in a fertilizer.
