Nute mixing ratio

Im currently using Cal mag from TPS n Mega crop Part A, I also got a Bloom booster from TPS i want start using since i flipped to flower the otherday, jus not sure how mix so Should i add Cal Mag, Booster then Mega Crop?? if some1 could help that be dope.

Also with the mega crop 2 part it says add Part B first which is the cal mag, but im only using Part A n Organic Cal Mag from TPS which i always add before MC, i notcied when the nutes are all mixed up the water looks cloudy is this right or have i been fuckin up??
