N and P. Are these forbidden to fertilize the water column in an Apisto planted tank? Which are the best strategies to do it?
No, you can add fertilizers. Nitrate (NO3) isn't toxic to fish (even at quite elevated levels) when it is added a salt (from KNO3) rather than being the "smoking gun" of previously elevated levels of NO- and NH3/NH4+.N and P.

That sounds like a nitrogen deficiency.My duckweed and Pistias are showing some kind of deficiency. Probably N. They are a little yellowish, pale growing, but I am adding regularly very little K+, Ca2+, Mg2+ and micros. I was afraid of using it as KNO3 in my apisto tank although I do it in my planted tank
Yes, you want to remove the NH3/NH4+ and NO2- as rapidly as possible. I like high levels of oxygenation and plenty of plants. If you can ensure that the oxygen supply always exceeds the Biochemical Oxygen Demand (BOD) then you have nitrification covered.as Apistos are said to be sensitive (I suppose they are then sensitive primarily to NH3/NH4+ and NO2-).
