I agreed with Roberta. Maybe too much of everything, even company. Draculas like to be alone, very quite and no disturb. I don't even use fertilizer one s months, 1 mother I drop some shelf and 1 very carefully no too much 1/4 of the indicated 20.20.20 and drops of magnesio-calcio. Anything stronger will burn the roots and leaves. Also, the temperature is really important a significant drop at night.
