me personally id go with week 1-2 then right to week 2 in bloom but thats me.and yeah you can use molasses throughout the grow.its more of a flower additive really but its great all through it especially if you dont have a cal mag supplement which ya should have.start small and less is more with autos.a good rule to not over do it to start with.thats what I did and most do when following base schedules.
and for autos.lets say the feed right now was 10 ml per gallon for example.Id use if you were gonna feed soon something like 3 ml per gallon,or maybe 4 but you have other things to add so again,less is more when combining things to start with.thats a good rule thats served me well when I fed from bottles.but im not really familiar with that brand,sooooo.hope that helps man.
