advanced nutes schedule.....autoflowering strains ....?..help?

hey im new to growing autos ive come to the point of preflowers on
my big bud/n.l. autos and my little devil (pure lowryder) strains
and im confused as to what schedule to use for my nutrients
i have the 3 part nutes Bloom Grow Micro,B52,Bud blood,big bud,and Carboload
and looking at the schedule on the website it seems a bit confusing for autos
so far i gave them one feeding with the 3part 1g bud blood 1/2g carboload per 2l water
has anyone used these nutes in the past that can guide me these nutrients
sound great but i have to admit theyre a bit confusing ....i was just gonna ease my way into it and
do some hands on learning but i thought maybe someone out there could help drop some knowledge

u fed them micro grow and bloom at the same time?

yes ...the nutrient chart for flowering says to use all three together throughout the life cycle
which to me seemed a bit odd but the additives ,like bud blood and big bud offset the ratio
so i dont know i havent used these nutes before but i got a good deal G,B,M bud blood big bud b52 and carboload for around 80-85$
but anyway thats why i asked ...to get someone with more experience if you have any info
would be much appreciated
