Could anyone discuss this subject ?
The only K I add comes from TMG and little KH2PO4.
Nitrates come from Ca(NO3)2 and Mg(NO3)2...
P and N are stable from week to week but K is raising.

Thanks in advance !

K is most certainly assimilated by plants. Perhaps your tapwater is
relatively high in K and the additional K from the TMG is too high of a
dose.
