m0useanswered grow question 3 years ago Could match the same brand as what you have been using in Veg,
I like dry amendments in growing, different style of feeding and use vs liquid nutrients.
Almost all liquid fertilizers use the same active things things for NPK, but its there extras in them that make them different like PH stabilizers, so they can react to one another like Roberts said.
Down to Earth, Dr,Earth, Gaia Green are a few brands I like.
Best Of Luck!
