Hello. I'm one week 1 of 12/12 flowering. Using a 110 watt t5 HO set up with 6 cfls. Growing in Fox Farm Ocean Forest with 30% perlite. I have used RO water thru out my whole grow. I will start hitting the nutes steadily during flower. My question is, do I still need to throw in the Cal mag with my fox farm nutes during feeed (BB, GB, TB?) Being I'm using RO water. I Have been using Cal mag bionicaire Plus at about 1/2 strenght every other or every 1/3 watering. I used the big bloom on one feeding last week and that's it. Thanks in advance for your input.
