i didn't vote because i haven't used enough lines of nutes, but i can say that after switching to jack's classic for bloom (from ff) the results were very similar. in fact, with the jack's my leaves stay greener longer, so it might have a bit of an edge there. i paid less than 10 bucks for a 1.5 lb tub of jack's which is sure to last me close to 2 years. the ff trio costs around 50 bucks, doesn't last as long, and due to its liquid form it can go bad after some time. i do like the ff big bloom, though. it won't sustain a plant on its own but it's great for plants that may be sensitive or overnuted, and if you do the flushing thing it's a good product to use for the last couple weeks instead of the heavier chemical stuff.
