Plants can always surprise you that's the fun part anyway...

The following specs are given just as information on how lean a tank can be run:

My tank water is just a little above 7ppm Ca2+ and 1ppm Mg2+, GH about 21ppm. NO3 hovering around 0,5 to 2ppm max. (calibrated kit). Tank with ADA soil Amazonia. Fertilization daily: small amounts of KNO3 as the sole N source plus KH2PO4, MgSO4, Brighty K, trace and lots of CO2 mist. Stable param's and no stunting or curly leaves for months now. Not the fastest of growth which may be due to medium light of around 2WPG. So, you can definitely go that low. I presume this is not too far away from ADA's water values...

Kekon, thanks again for taking time and replying.

Best regards,
Detlef
