I've been using medina hasta grow fertilizer. 6-12-6 through the veg and I'm now 2 weeks into flowering. As I understand it... would be better to lower N levels and increase the P-K? I was hoping for recommendation on a organic fertilizer for flowering. Just 2 cents... I've found the Medina fert. to give pretty good results. Only comparison is with GH 3part. I would say it was much easier and results are very similar.
