I googled for potion recipes for vv3. I found a website,which I forgot. I try made,and the result is wrong. so I google again and found another site. I found out there we can get pink diamond from rose,orchid,and cactus.but everytime I made that potion,its burns.I cant get pink diamond

whats wrong? do most website give me wrong recipes,or there are different way to create recipe on vv3?
