Hi sllo,

personally, I do not believe in deficiency pictures. There is too many combinations and too many look alike symptoms, it is impossible to list them all.
Usually reading the aquarium water parameters before WC reveal the cause of most deficiencies. We need, NO3, PO4, Ca, Mg, CO2, KH, pH, Wpg, TDS, and how do you dose K and TE Trace Elements.

Hi sllo,

sorry, I didn't see your previous post, was lost in a buffer.

1. keep NO3 at 15 ppm, measured before WC. Calibrate your NO3 kit, see Fertilizing forum FAQ.
2. dose the same grams of K2SO4 as KNO3, this will give you NO3:K 3:4, no need to dose more K
3. dosing Mg without knowing tap Mg and Ca is difficult. Dosing 10 ppm Mg a week is generally good. Lets hope your tap or substrate has Ca.
4. you are dosing lots of TE. What kind of TE is it?

the only TE I can get here are Florena by Sera and Froralpride from Tetra.
Any analysis available?

I have a cheap Fe test kit from sera and I try to keep the Fe around 1ppm.
Fe test kits never helped me with anything.

What substrate do you have?
