growing outside... michigan.. identified brown spots and blotches as a calcium-or mag deficiency.. i have 3 weeks left of flower.. bought some cal-mag.. i plan on flushing my soil really good before i add.. how strong should i mix it introducing it to the plant? half strength? and can i add it withy fox farm tiger bloom and big bloom? ph water is 6..3 usually.. and for future grows should i add cal mag every once in a while?
