im not positive since i went with the other one, but yes you should use them seperately i believe. they have both a veg, and a bloom formula. i would use molasses too. then if you need a little nitrogen(during flowering) i would add a little grow formula or some wormcastings only if it showed a defficency in the early stages of flowering, after the 4 week mark id just let the leaves fall when they want too.
