Stinky i have a simple question that's sooo simple i have no idea how to find the bloody answer...

I put my plants onto 12/12 2 days ago,they were eating CHEMPAK No2 HNF 25+15+15 and they thrived but now (after hours of searching) i'd like to know what you'd advise me to move them onto for the Flowering stage...I was thinking of using the CHEMPAK No4 which is 15+15+30 and realy after all this waffling would like to hear what you'd use..Edit:Use as in ?+?+? (Is is called the NPK table ? Nitrogen/Phosphate/Potash)

Thanks in advance..
