When flowering started i was using only tiger bloom at about 1 tsp per gallon. when i got the big bloom i gave them a full 2 tbs dose but no tiger bloom. now i am using just as the ff feeding schedule says: 2 tsp tiger bloom and 1 tbs big bloom and i mix them in the same gallon of water. my ph meter is a piece of shit so i have only been ph-ing the water i have in my grow room.(i keep all my grow h2o in a big rubbermaid trash can in my grow room so it is all room temp.) i don't ph the fert mix, i just give the ladies some powderized garden lime about 2 times a month, great calcium 1 tsp per gallon. as u can see i think they like this very much. just be careful when feeding, start with less and add a bit more every time until u get it to where u want. good luck to u man:thumbsup:
