Just overly fortified to begin with. Those NPK numbers on the MG bags are decieving because of other stuff they "miracle-ize" their products with for most average growers who will be outdoors or in some kind of sunlight and thus get the usual watering transpiration from.

Indoors under non HID lighting - you gotta be careful how much Nitrogen (castings) you use.

Any simple pH mistaken target over 6.4 or so will get us nute lock with those castings - every single time - indoors - and under non HID lighting.
