nice, what about coffee treatment?

for my place, I have a northiana in pure burn soil(big pieces), once I watered it, it will remain wet for a long time, which is around 5 days, causes the old leaves to have same effect of my repotted n. campanulata, after reducing watering, it shows sign of recovering, but pitchering inconsistently as some times it does grow 1 cm pitcher, some times none...
