The unlabeled bag is Mega Crop, that's the plant food you use all the way through. The others Carbo is just a carb booster used in week 3-6/7 Big Up is the bloom booster also used in week 3-6/7 once a week and Rock Steady is a K booster only used around week 6/7 but only when flushing as it's 1200 ppm at 1gram/1L
There should have been label on the bad maybe I forgot it or it fell off. Keep that bag closed when not in use as its hygroscopic and will absorb moisture and bacome a brown sticky mess in a couple of days.
