I have been using coffee once a month on two of my neps and it seems to have had the desired effect of making them grow faster but the growth has been a little odd so I'm statring to wonder if I'm using too much coffee. They are probably fine since they are still pitchering and don't show any signs of over fertilization but maybe someone on here has had something similar happen. The plants are veitchii k and black truncata. The truncata is the one that has had the most odd growth. The leaves have taken to flattening out and then curling back up at the ends. Also the shape of the newest leaf is a bit odd and its at least twice the size of the last leaf which was already at least twice the size of the leaf before that. The veitchii has only shown the waviness in the leafs in this last leaf so it may just be a fluke.
