YES, do exactly what the feeding schedule says, i use foxfarms nutes with great successs, the fuckin big bloom is real nice shit man, you can practically pour it straight outta the bottle on your plants it is so weak, but in hindsight don't mistake how weak big bloom is for how important it is. the plants simply love it. just pray that your soil mix is good and free of any time release funk nutes, cuz that will leed to complications come late flower, believe me, been there, fucked that up... but now i got my soil in check and i am using FF and cal mag for my grow and there is no signs of overfeediong at all. it says to use straight water for every other watering, but I substitute that with 3tsp big bloom and 1/2tsp calmag. then when it comes feeding time i blast them with all that they need. it's working awesome for me this way. also, you should invest in the open sesame,beastie bloomz, and cha ching , (they are part of the flowering schedule in conjuction with the nutes you alrdy bought) , i know they are fuckin pricey but hey, they will last ya a long fuckin time. outta the whole lineup big bloom gets used the most. for every quart of grow big and tiger bloom used, i would say i go through a gallon or two of big bloom........ big bloom is good stuff bro, dont be scared of overdoin it with big bloom cuz you will have a hard time, use caution while administering all the rest though cuz they are quite a bit more strong and could hurt them gals a lot more than the big bloom ever could. all in all i am very satisfied with foxfarm nutrients though... they work
