Second that. That's insane. Spec on tap water. You might be creeping up to 180+ ppm of Ca depending on the water. Granted if Using Reg GB it doesn't have Ca in it. If using the Hydro it's way too much.
I'm not sure where the whole mantra of kushes being
calmg whores comes from. It's one or the other. Maybe mag whores if you normally run it low but I have never seen plants that will take up more Ca then another as long as you are running enough in the first place. Same with Mg really also. If anyone uses
calmg as one nutrient together as a requirement don't listen to them. They prob don't have a good understanding of nutes. Everything likes N in flower minus 14+ week pure sativas with thin 11 bladed leaves which wouldn't be an indoor plant in the first place. SFV, Tahoe ect all ate up over 100 ppm of N in flower for me from day 1. Never adjusted my nutes on kushes. Never needed to. If people run into problems with kushes their mix wasn't that good to begin with. Just being real. Trust me guys running 1000's of plants in a warehouse don't go adjusting feeds for specific plants. Just PPM's/EC and most of the time will find a medium to keep it level across the board. Indoors ofc greenhouses and OD is a diff story and a totally diff game and equipment.
