Have always used promix hp , and have experienced potassium and magnesium deficiency’s that starts mid bloom leaves dying from the tip back. My plants grow excellent during veg. I can ph my water wherever I want, when you check run off, its 5.5 no matter what. It seems to cause problems during bud development. I’ve read other people have had ph issues with promix.. I use gh flora series, moderate strength.
