Hi everyone I'm basically using general organics bio thrive gro which obviously contains NPK but have bought some cal mag plus which also contains NPK?? Can I use these together or will it be too much. I'm currently using these at half dose so was maybe going to halve again and use both ?? Thanks in advance Sent from my iPhone using Grasscity Forum
