So if my tap water is 188 ppm I should add 1012ppm then the following week 1112 ppm and so on and so forth? What about big bud? Should I back off the bloom a+b to half and make up the difference with big bud? I really appreciate your help. The lants look lime green and the lower fans are yellowing. A little soon IMO only going into third week of flower. My ppm with 188 ppm tapp water now are 1039ppm.
