I have been fertilizing my paphs about every two weks with a weak solution (currently of Hauserman's Fertilaide Fertilizer liquid 15-5-5). Unless they are in bloom or spike. I use mostly dehumidifier water, with the occasional drink of local tap water, which is pretty hard. Prior to using the Hauserman's liquid fertilizer, I was using dilute (quarter-strength) Peter's balanced fertilizer. Copuld I be doing better? I haven't killed anything yet. Should I be fertilizing while the plants are blooming? Thanks for any advice.
