I have 3 discus that I feed 5 times a day (automatic feeder with flake food
4 times a day), and beefheart 1 big piece a day...
so I have enough nitrates and po4...


sometimes I have lack of NO3, bellow 5 ppm, in those times I put some KNO3
to achieve a level of 5 ppm. (this is extremely rare)

PO4 is non existent on the water (it's what my test says ), but my plant
stick fertilizer that I use ... sometimes...have a big ratio of PO4 versus
nitrate.

Regards!

I forgot to mention my tank parameters
KH-3
pH-6.7
GH-6

250 liters (66 gallon)
300 watts MH.
DIY CO2 (3 bottles of 2 liters)
10 ml of TMG

How much nitrate are you adding to that tank? There's none in TMG, if I
recall correctly.
